4. (Paragraph 2) This type of learning, however, is called conditioning. The animal simply learns that when it performs a particular behaviour, it gets a reward, usually a fish. Many animals, including rats, birds, and even invertebrates, can be conditioned to perform tricks. We certainly don't think of these animals as our mental rivals. Unlike most other animals, however, dolphins quickly learn by observations and may spontaneously imitate human activities. One tame dolphin watched a diver cleaning an underwater viewing window, seized a feather in its beak, and began imitating the diver---complete with sound effects! Dolphins have also been seen imitating seals, turtles,and even water-skiers.  According to the passage, which of the following animals is most likely to learn by watching another animal perform an activity?

Explanation

The passage states that dolphins are able to quickly learn by observation and may spontaneously imitate human activities. It gives an example of a dolphin imitating a diver cleaning an underwater viewing window. Therefore, dolphins are the most likely animal to learn by watching another animal perform an activity.

5. PARAGRAPH 5 The answer, in one word, is aggression.  Chipmunk species actively defend their ecological zones from encroachment by neighboring species. The yellow pine chipmunk is more aggressive than the sagebrush chipmunk, possibly because it is a bit larger. It successfully bullies its smaller evolutionary cousin, excluding it from the pine forests. Experiments have shown that the sagebrush chipmunk is physiologically able to live anywhere in the Sierra Nevada, from high alpine zones to the desert. The little creature is apparently restricted to the desert not because it is specialized to live only there but because that is the only habitat where none of the other chipmunk species can live. The fact that sagebrush chipmunks tolerate very warm temperatures makes them, and only them, able to live where they do. The sagebrush chipmunk essentially occupies its habitat by default. In one study, ecologists established that the yellow pine chipmunks actively exclude sagebrush chipmunks from pine forests; the ecologists simply trapped all the yellow pine chipmunks in a section of forest and moved them out. Sagebrush chipmunks immediately moved in, but yellow pine chipmunks did not enter the sagebrush desert when sagebrush chipmunks were removed.   8) The word "encroachment" in the passage is closest in meaning to  

Explanation

The word "encroachment" in the passage refers to the act of gradually invading or intruding upon someone else's territory or space. It implies a slow and persistent takeover rather than complete destruction or excessive development. This is supported by the context in which it is mentioned, as the paragraph discusses how chipmunk species actively defend their ecological zones from neighboring species, suggesting a gradual invasion of territory by one species over another. Therefore, "gradual invasion" is the closest meaning to "encroachment" in this context.

Submit
6. Now answer the question.

Explanation

The statement "It takes a lot of time to evaluate a piece of art" is the correct answer because it is the only statement that directly relates to the fact that the person will assign 12 pieces of art to evaluate. The other statements about organizing a class trip to the art museum and students being able to evaluate art quickly are not directly related to the task of evaluating 12 pieces of art.

Submit
7. The word "hazards" in the passage is closest meaning to

Explanation

In the passage, the word "hazards" refers to potential dangers or risks. It indicates that there are certain things or situations that can cause harm or be unsafe. The word "objects" does not convey the same meaning as hazards, as hazards imply a level of danger or risk. Similarly, "species" and "debris" do not accurately capture the meaning of hazards in this context.

Submit
8. The word "concentrated" in the passage is closest in meaning to

10. According to the passage, why are the studies that conclude that dolphin intelligence is "somewhere between that of a dog and a chimpanzee" not correct?

Explanation

The passage suggests that the studies concluding that dolphin intelligence is "somewhere between that of a dog and a chimpanzee" are not correct because the human method of drawing comparisons is not relevant to animal intelligence. This implies that using human standards to compare animal intelligence is not appropriate, as different species may have different types and levels of intelligence. Therefore, the studies' conclusions based on such comparisons are not accurate.

Submit
11. Why does the woman tell the man about her own experience as a student?

Explanation

Submit
13. In paragraph 2, the author indicates that a large variety of chipmunk species exist in western North America because of

Explanation

The correct answer is the ecological variety and extremes of the West that caused chipmunks to become geographically isolated. This is supported by the statement in paragraph 2 that mentions the ecological variety and extremes of the West as the reason for the existence of a large variety of chipmunk species in western North America. The author implies that these ecological factors have led to the chipmunks becoming geographically isolated, which in turn has contributed to the development of different species.

Submit
14. According to the professor, what did a 1920 telescope allow astronomers to do for the first time?

Explanation

A 1920 telescope allowed astronomers to reject the dust theory of nebulae for the first time. This suggests that prior to the development of this telescope, astronomers did not have the capability to gather enough evidence to disprove the theory that nebulae were composed of dust. The 1920 telescope likely provided new insights or data that contradicted the prevailing belief, leading astronomers to reject the dust theory.

15. (Paragraph 5)  Studies by Park, Burgess, and other Chicago-school sociologists showed how new groups of immigrants tended to be concentrated in separate areas within inner-city zones where they sometimes experienced tension with other ethnic groups that had arrived earlier. Over time, however, each group was able to adjust to life in the city and to find a place for itself in the urban economy. Eventually many of the immigrants moved to unsegregated areas in outer zones; the areas they left behind were promptly occupied by new waves of immigrants. The word "they" in the passage refers

Explanation

The word "they" in the passage refers to the new groups of immigrants. The passage discusses how these new groups of immigrants tend to be concentrated in separate areas within inner-city zones and eventually adjust to life in the city. It also mentions that these areas are promptly occupied by new waves of immigrants once the previous group moves to unsegregated areas in outer zones. Therefore, "they" refers to the new groups of immigrants who occupy the areas left behind by the previous group.

17. (Paragraph 3)  Given the seeming intelligence of cetaceans, people are always tempted to compare them with humans and other animals. Studies on discrimination and problem-solving skills in the bottlenose dolphins, for instance, have concluded that its intelligence lies "somewhere between that of a dog and a chimpanzee." Such comparisons are unfair. It is important to realize that intelligence is a very human concept and that we evaluate it on human terms. After all, not many people would consider themselves stupid because they couldn't locate and identify a fish by its echo. Why should we judge cetaceans by their ability to solve our problems? The word "tempted" in the passage is closest in meaning to:

Explanation

The word "tempted" in the passage is closest in meaning to "inclined". This means that people are naturally inclined or have a tendency to compare cetaceans with humans and other animals due to their seeming intelligence. The word "tempted" suggests that there is a strong inclination or desire to make these comparisons.

Submit
18. The word "outermost" in the passage is closest in meaning to

Give yourself 20 minutes to complete this practice set.  CETACEAN INTELLIGENCE  We often hear that whales, dolphins, and porpoises are as intelligent as humans, maybe even more so. Are they really smart? There is no question that cetaceans are among the most intelligent of animals. Dolphins, killer whales, and pilot whales in captivity quickly learn tricks. The military has trained bottlenose dolphins to find bombs and missile heads and to work as underwater spies.  This type of learning, however, is called conditioning. The animal simply learns that when it performs a particular behavior, it gets a reward, usually a fish. Many animals, including rats, birds, and even invertebrates, can be conditioned to perform tricks. We certainly don't think of these animals as our mental rivals. Unlike most other animals, however, dolphins quickly learn by observations and may spontaneously imitate human activities. One tame dolphin watched a diver cleaning an underwater viewing window, seized a feather in its beak, and began imitating the diver –complete with sound effects! Dolphins have also been seen imitating seals, turtles, and even water-skiers.  Given the seeming intelligence of cetaceans, people are always tempted to compare them with humans and other animals. Studies on discrimination and problem-solving skills in the bottlenose dolphin, for instance, have concluded that its intelligence lies "somewhere between that of a dog and a chimpanzee." Such comparisons are unfair. It is important to realize that intelligence is a very human concept and that we evaluate it in human terms. After all, not many people would consider themselves stupid because they couldn't locate and identify a fish by its echo. Why should we judge cetaceans by their ability to solve human problems?  Both humans and cetaceans have large brains with an expanded and distinctively folded surface, the cortex. The cortex is the dominant association center of the brain, where abilities such as memory and sensory perception are centered. Cetaceans have larger brains than ours, but the ratio of brain to body weight is higher in humans. Again, direct comparisons are misleading. In cetaceans it is mainly the portions of the brain associated with hearing and the processing of sound information that are expanded. The enlarged portions of our brain deal largely with vision and hand-eye coordination. Cetaceans and humans almost certainly perceive the world in very different ways. Their world is largely one of sounds, ours one of sights.  Contrary to what is depicted in movies and on television, the notion of "talking" to dolphins is also misleading. Although they produce a rich repertoire of complex sounds, they lack vocal cords and their brains probably process sound differently from ours. Bottlenose dolphins have been trained to make sounds through the blow-hole that sound something like human sounds, but this is a far cry from human speech. By the same token, humans cannot make whale sounds. We will probably never be able to carry on an unaided conversation with cetaceans.  As in chimpanzees, captive bottlenose dolphins have been taught American Sign Language. These dolphins have learned to communicate with trainers who use sign language to ask simple questions. Dolphins answered back by pushing a "yes" or "no" paddle. They have been known to give spontaneous responses not taught by trainers. Evidence also indicates that these dolphin can distinguish between commands that differ from each other only by their word order, a truly remarkable achievement. Nevertheless, dolphins do not seem to have a real language like ours. Unlike humans, dolphins probably cannot convey very complex messages.  Observations of cetaceans in the wild have provided some insights on their learning abilities. Several bottlenose dolphins off western Australia, for instance, have been observed carrying large cone-shaped sponges over their beaks. They supposedly use the sponges for protection against stingrays and other hazards on the bottom as they search for fish to eat. This is the first record use of tools among wild cetaceans.  Instead of "intelligence," some people prefer to speak of "awareness." In any case, cetaceans probably have a very different awareness and perception of their environment than do humans. Maybe one day we will come to understand cetaceans on their terms instead of ours, and perhaps we will discover a mental sophistication rivaling our own.  Directions: Now answer the questions.  Paragraph 1  We often hear that whales, dolphins, and porpoises are as intelligent as humans, maybe even more so.

Submit
27. Why does the professor mention that drought is often blamed as the cause of the Dust Bowl?

Explanation

The professor mentions that drought is often blamed as the cause of the Dust Bowl to emphasize that the Dust Bowl resulted mainly from soil erosion. This suggests that while drought may have been a contributing factor, it was the erosion of the soil that led to the severe dust storms and environmental devastation of the Dust Bowl. By highlighting soil erosion as the main cause, the professor is likely emphasizing the importance of sustainable farming practices and the need to prevent future ecological disasters.

Evidence also indicates that these dolphin can distinguish between commands that differ from each other only by their word order, a truly remarkable achievement. Nevertheless, dolphins do not seem to have a real language like ours. Unlike humans, dolphins probably cannot convey very complex messages. The word "spontaneous" in the passage is closest in meaning to:

Explanation

The word "spontaneous" in the passage is closest in meaning to "unprompted". This means that the dolphins are giving responses without being prompted or taught by the trainers. They are able to communicate in a natural and unplanned way, showing their intelligence and ability to understand and respond to sign language.

36. PARAGRAPH 3  Most ecologists believe that ancient populations of chipmunks diverged genetically when isolated from one another by mountains and unfavorable ecological habitat. These scattered populations first evolved into races - adapted to the local ecological conditions - and then into species, reproductively isolated from one another. This period of evolution was relatively recent, as evidenced by the similar appearance of all the western chipmunk species. The word "diverged" in the passage is closest in meaning to

Explanation

The word "diverged" in the passage is closest in meaning to "separated" because it suggests that the ancient populations of chipmunks were isolated from one another by mountains and unfavorable ecological habitat, leading to their genetic divergence and reproductive isolation. This implies that they were separated from one another and developed into different races and eventually species.

41.  Directions: Read the passage. Then answer the questions. Give yourself 20 minutes to complete this practice set.  A MODEL OF URBAN EXPANSION  In the early twentieth century, the science of sociology found supporters in the United States and Canada partly because the cities there were growing so rapidly. It often appeared that North American cities would be unable to absorb all the new-comers arriving in such large numbers. Presociological thinkers like Frederick Law Olmsted, the founder of the movement to build parks and recreation areas in cities, and Jacob Riis, an advocate of slum reform, urged the nation's leaders to invest in improving the urban environment, building parks and beaches, and making better housing available to all. These reform efforts were greatly aided by sociologists who conducted empirical research on the social conditions in cities. In the early twentieth century, many sociologists lived in cities like Chicago that were characterized by rapid population growth and serious problems. It seemed logical to use empirical research to construct theories about how cities grow and change in response to major social forces as well as more controlled urban planning.  The founders of the Chicago school of sociology, Robert Park and Ernest Burgess, attempted to develop a dynamic model of the city, one that would account not only for the expansion of cities in terms of population and territory but also for the patterns of settlement and land use within cities. They identified several factors that influence the physical form of cities. As Parks stated, among them are "transportation and communication, tramways and telephones, newspapers and advertising, steel and construction and elevators–all things, in fact, which tend to bring about at once a greater mobility and a greater concentration of the urban populations."  Park and Burgess based their model of urban growth on the concept of "natural areas"–that is, areas such as occupational suburbs or residential enclaves in which the population is relatively homogeneous and land is used in similar ways without deliberate planning. Park and Burgess saw urban expansion as occurring through a series of "invasions" of successive zones or areas surrounding the center of the city. For example, people from rural areas and other societies "invaded" areas where housing was inexpensive. Those areas tended to be close to the places where they worked. In turn, people who could afford better housing and the cost of commuting "invaded" areas farther from the business district.  Park and Burgess's model has come to be known as the "concentric zone-zone model" (represented by the figure). Because the model was originally based on studies of Chicago, its center is labeled "Loop," the term commonly applied to that city's central commercial zone. Surrounding the central zone is a "zone in transition,"  an area that is being invaded by business and light manufacturing. The third zone is inhabited by workers who do not want to live in the factory or business district but at the same time need to live reasonably close to where they work. The fourth or residential zone consists of upscale apartment buildings and single-family homes. And the outermost ring, outside the city limits, is the suburban or commuters' zone; its residents live within a 30- to 60-minute ride of the central business district.  Studies by Park, Burgess, and other Chicago-school sociologists showed how new groups of immigrants tended to be concentrated in separate areas within inner-city zones where they sometimes experienced tension with other ethnic groups that had arrived earlier. Over time, however, each group was able to adjust to life in the city and to find a place for itself in the urban economy. Eventually many of the immigrants moved to unsegregated areas in outer zones; the areas they left behind were promptly occupied by new waves of immigrants.  The Park and Burgess model of growth in zones and natural areas of the city can still be used to describe patterns of growth in cities that were built around a central business district and that continue to attract large numbers of immigrants. But this model is biased toward the commercial and industrial cities of North America, which have tended to form around business centers rather than around palaces or cathedrals, as is often the case in some other parts of the world. Moreover, it fails to account for other patterns of urbanization, such as the rapid urbanization that occurs along commercial transportation corridors and the rise of nearby satellite cities.  Directions: Now answer the questions.  (Paragraph 1) In the early twentieth century, the science of sociology found supporters in the United States and Canada partly because the cities there were growing so rapidly.

Explanation

Both Olmsted and Riis were presociological thinkers who advocated for improving the urban environment and making better housing available to all. They both wanted to improve the conditions of life in cities, which is evident from their efforts to build parks, advocate for slum reform, and invest in improving the urban environment. The passage states that their reform efforts were greatly aided by sociologists who conducted empirical research on the social conditions in cities, suggesting that they were focused on improving the living conditions in cities.

Submit
44. What point does the professor make when he mentions that good topsoil takes thousands of years to form?

Explanation

The professor's point in mentioning that good topsoil takes thousands of years to form is that it was wrong to believe that land could not be damaged. The fact that it takes a long time for topsoil to form implies that it is a finite resource that can be depleted or damaged if not properly managed. This challenges the belief that land is invincible and can sustain unlimited exploitation without consequences.

45. According to the lecture, how did distant galaxies appear to eighteenth-century astronomers?

Explanation

According to the lecture, distant galaxies appeared to eighteenth-century astronomers like small clouds. This suggests that astronomers observed these galaxies as faint, diffuse objects in the sky, resembling the appearance of small clouds rather than distinct points of light like stars or moons of planets.

Submit
46. Which of the following statements is supported by the results of the experiment described at the end of paragraph 5?

Explanation

The experiment described in paragraph 5 supports the statement that the habitat of the yellow pine chipmunk is desirable to other species, while the habitat of the sagebrush chipmunk is not. This can be inferred from the fact that it was easier to remove yellow pine chipmunks from their habitat compared to sagebrush chipmunks. The difficulty in removing the sagebrush chipmunks suggests that their habitat is less desirable and potentially more suitable for their survival, as they may have adapted to the specific conditions of their habitat.

47. (Paragraph 2)  The founders of the Chicago school of sociology, Robert Park and Ernest Burgess, attempted to develop a dynamic model of the city, one that would account not only for the expansion of cities in terms of population and territory but also for the patterns of settlement and land use within cities. They identified several factors that influence the physical form of cities. As Parks stated, among them are "transportation and communication, tramways and telephones, newspapers and advertising, steel and construction and elevators–all things, in fact, which tend to bring about at once a greater mobility and a greater concentration of the urban populations." Which of the sentences below best expresses the essential information in the highlighted sentence in paragraph 2? Incorrect choices change the meaning in important ways or leave out essential information.

Explanation

The sentence states that the model created by Park and Burgess was intended to explain the growth of population and territory in cities, as well as the patterns of settlement and land use within cities.

49. (Paragraph 7)  Observations of cetaceans in the wild have provided some insights on their learning abilities. Several bottlenose dolphins off western Australia, for instance, have been observed carrying large cone-shaped sponges over their beaks. They supposedly use the sponges for protection against stingrays and other hazards on the bottom as they search for fish to eat. This is the first record use of tools among wild cetaceans. The word "insights" in the passage is closest in meaning to:

Explanation

The word "insights" in the passage refers to the knowledge or understanding gained from observing cetaceans in the wild. It suggests that through these observations, researchers have gained a deeper understanding of the learning abilities of cetaceans. Therefore, the closest meaning to "insights" in this context is "understanding".

50. PARAGRAPH 6 The most aggressive of the four eastern-slope species is the lodgepole chipmunk, a feisty rodent indeed. It actively prevents alpine chipmunks from moving downslope, and yellow pine chipmunks from moving upslope. There is logic behind the lodgepole's aggressive demeanor. It lives in the cool, shaded conifer forests, and of the four species, it is the least able to tolerate heat stress. It is, in other words, the species of the strictest habitat needs: it simply must be in those shaded forests. However, if it shared its habitat with alpine and yellow pine chipmunks, either or both of these species might outcompete it, taking most of the available food. Such a competition could effectively eliminate lodgepole chipmunks from the habitat. Lodgepoles survive only by virtue of their aggression.  
  1. According to paragraph 6, why is the lodgepole chipmunk so protective of its habitat from competing chipmunks?

Explanation

The paragraph explains that the lodgepole chipmunk lives in cool, shaded conifer forests and is the least able to tolerate heat stress. It is stated that the lodgepole chipmunk is the species with the strictest habitat needs and must be in those shaded forests. If it shared its habitat with other chipmunk species, they might outcompete it for food, potentially eliminating the lodgepole chipmunks from the habitat. Therefore, the lodgepole chipmunk is protective of its habitat because it requires the shade provided by forest trees.

51. (Paragraph 4)  Park and Burgess's model has come to be known as the "concentric zone-zone model" (represented by the figure). Because the model was originally based on studies of Chicago, its center is labeled "Loop," the term commonly applied to that city's central commercial zone. Surrounding the central zone is a "zone in transition,"  an area that is being invaded by business and light manufacturing. The third zone is inhabited by workers who do not want to live in the factory or business district but at the same time need to live reasonably close to where they work. The fourth or residential zone consists of upscale apartment buildings and single-family homes. And the outermost ring, outside the city limits, is the suburban or commuters' zone; its residents live within a 30- to 60-minute ride of the central business district. According to paragraph 4, why is the term "Loop" used in concentric-zone model?

Explanation

The term "Loop" is used in the concentric-zone model because it reflects the fact that the model was created with the city of Chicago in mind. The model was originally based on studies of Chicago, and the center of the model is labeled "Loop," which is the term commonly applied to Chicago's central commercial zone. This indicates that the model was specifically designed to represent the urban structure of Chicago and may not be applicable to other cities.

52. (Paragraph 6)  The Park and Burgess model of growth in zones and natural areas of the city can still be used to describe patterns of growth in cities that were built around a central business district and that continue to attract large numbers of immigrants. But this model is biased toward the commercial and industrial cities of North America,  which have tended to form around business centers rather than around palaces or cathedrals, as is often the case in some other parts of the world. Moreover, it fails to account for other patterns of urbanization, such as the rapid urbanization that occurs along commercial transportation corridors and the rise of nearby satellite cities.  Paragraph 6 indicates which of the following about the application of the Park and Burgess model to modern North American cities?

Explanation

The given paragraph states that the Park and Burgess model can still be used to describe patterns of growth in cities built around a central business district and attracting large numbers of immigrants. However, it is biased towards commercial and industrial cities in North America and fails to account for other patterns of urbanization, such as rapid urbanization along transportation corridors and the rise of satellite cities. Therefore, the model remains useful in explaining the development of some urban areas, but not all cities.

53. Why does the professor talk about personal taste?

Explanation

The professor talks about personal taste in order to help students understand the meaning of aesthetics. By discussing personal taste, the professor is likely emphasizing that aesthetics is subjective and can vary from person to person. This helps students grasp the concept that there is no one right or wrong answer when it comes to evaluating art, and that personal preferences play a significant role in the understanding and appreciation of aesthetics.

Submit
54. According to the professor, what is an advantage of the Different-Cultures Model?

Explanation

The advantage of the Different-Cultures Model is that it includes the history of a variety of cultural groups. This means that it provides a comprehensive understanding of different cultures and their historical backgrounds, allowing for a more inclusive and diverse perspective. By including the history of various cultural groups, the model promotes a broader understanding of society and fosters cultural awareness and appreciation.

56. (Paragraph 8)  Instead of "intelligence,"some people prefer to speak of "awareness." In any case, cetaceans probably have a very different awareness and perception of their environment than do humans. Maybe one day we will come to understand cetaceans on their terms instead of ours, and perhaps we will discover a mental sophistication rivaling our own.  What does the author conclude about the intelligence of cetaceans?

Explanation

The author concludes that it is not appropriate to judge cetacean intelligence in human terms.

57. Directions: Read the passage. Then answer the questions. Give yourself 20 minutes to complete this practice set.  HABITAT AND CHIPMUNK SPECIES  There are eight chipmunk species in the Sierra Nevada mountain range, and most of them look pretty much alike. But eight different species of chipmunks scurrying around a picnic area will not be found. Nowhere in the Sierra do all eight species occur together. Each species tends strongly to occupy a specific habitat type, within an elevational range, and the overlap among them is minimal.     The eight chipmunk species of the Sierra Nevada represent but a few of the 15 species found in western North America, yet the whole of eastern North America makes do with but one species: the Eastern chipmunk. Why are there so many very similar chipmunks in the West? The presence of tall mountains interspersed with vast areas of arid desert and grassland makes the West ecologically far different from the East. The West affords much more opportunity for chipmunks populations to become geographically isolated from one another, a condition of species formation. Also, there are more extremes in western habitats. In the Sierra Nevada, high elevations are close to low elevations, at least in terms of mileage, but ecologically they are very different.     Most ecologists believe that ancient populations of chipmunks diverged genetically when isolated from one another by mountains and unfavorable ecological habitat. These scattered populations first evolved into races - adapted to the local ecological conditions - and then into species, reproductively isolated from one another. This period of evolution was relatively recent, as evidenced by the similar appearance of all the western chipmunk species.     Ecologists have studied the four chipmunk species that occur on the eastern slope of the Sierra and have learned just how these species interact while remaining separate, each occupying its own elevational zone. The sagebrush chipmunk is found at the lowest elevation, among the sagebrush. The yellow pine chipmunk is common in low to mid-elevations and open to conifer forests, including piñon and ponderosa and Jeffrey pine forests. The lodgepole chipmunk is found at higher elevations, among the lodgepoles, firs, and high-elevation pines. The alpine chipmunk is higher still, venturing the talus slopes, alpine meadows, and high-elevation pines and junipers. Obviously, the ranges of each species overlap. Why don't sagebrush chipmunks move into the pine zones? Why don't alpine chipmunks move to lower elevations and share the conifer forests with lodgepole chipmunks? The answer, in one word, is aggression.  Chipmunk species actively defend their ecological zones from encroachment by neighboring species. The yellow pine chipmunk is more aggressive than the sagebrush chipmunk, possibly because it is a bit larger. It successfully bullies its smaller evolutionary cousin, excluding it from the pine forests. Experiments have shown that the sagebrush chipmunk is physiologically able to live anywhere in the Sierra Nevada, from high alpine zones to the desert. The little creature is apparently restricted to the desert not because it is specialized to live only there but because that is the only habitat where none of the other chipmunk species can live. The fact that sagebrush chipmunks tolerate very warm temperatures makes them, and only them, able to live where they do. The sagebrush chipmunk essentially occupies its habitat by default. In one study, ecologists established that the yellow pine chipmunks actively exclude sagebrush chipmunks from pine forests; the ecologists simply trapped all the yellow pine chipmunks in a section of forest and moved them out. Sagebrush chipmunks immediately moved in, but yellow pine chipmunks did not enter the sagebrush desert when sagebrush chipmunks were removed.     The most aggressive of the four eastern-slope species is the lodgepole chipmunk, a feisty rodent indeed. It actively prevents alpine chipmunks from moving downslope, and yellow pine chipmunks from moving upslope. There is logic behind the lodgepole's aggressive demeanor. It lives in the cool, shaded conifer forests, and of the four species, it is the least able to tolerate heat stress. It is, in other words, the species of the strictest habitat needs: it simply must be in those shaded forests. However, if it shared its habitat with alpine and yellow pine chipmunks, either or both of these species might outcompete it, taking most of the available food. Such a competition could effectively eliminate lodgepole chipmunks from the habitat. Lodgepoles survive only by virtue of their aggression.   Directions: Now answer the questions.  PARAGRAPH 1 There are eight chipmunk species in the Sierra Nevada mountain range, and most of them look pretty much alike.

Each species tends strongly to occupy a specific habitat type, within an elevational range, and the overlap among them is minimal. 
  1. Why does the author mentions a "picnic area" in paragraph 1?
 

Explanation

The author mentions a "picnic area" in paragraph 1 to support the point that each species of chipmunk inhabits a distinct location. The statement that "eight different species of chipmunks scurrying around a picnic area will not be found" implies that each species tends to occupy a specific habitat type within an elevational range, and the overlap among them is minimal. This reinforces the idea that chipmunk species have specific habitat preferences and do not coexist in the same area.

58. Paragraph 5 mentions all of the following as true of the relationship of sagebrush chipmunks to their habitats EXCEPT:

Explanation

The passage states that sagebrush chipmunks are able to survive in any habitat of the Sierra Nevada, occupy their habitat because of the absence of competition from other chipmunks, and are better adapted to survive in hot temperatures than other species of chipmunks. However, it does not mention anything about sagebrush chipmunks spending the warm season at the higher elevations of the alpine zone.

60. What aspect of Islamic civilization will the professor likely discuss in the course?

Explanation

The professor is likely to discuss Islamic elements in African cultures because the question asks about a specific aspect of Islamic civilization. The other options, such as a succession of Islamic rulers, the ancient origins of Islamic architecture, and the isolation of European cultures from Islamic influence, are not directly related to African cultures. Therefore, the most relevant topic for the professor to discuss in this course would be the Islamic elements present in African cultures.

61. What could astronomers better estimate once they knew what nebulae really were?

Explanation

Once astronomers knew what nebulae really were, they would have a better understanding of the composition and structure of these celestial objects. This knowledge would enable them to make more accurate estimates of the size of the universe, as nebulae are vast clouds of gas and dust that are spread across galaxies. By studying the properties of nebulae, astronomers can gather information about the distribution and extent of matter in the universe, allowing for a more precise estimation of its size.

62. (Paragraph 3) Park and Burgess based their model of urban growth on the concept of "natural areas"–that is, areas such as occupational suburbs or residential enclaves in which the population is relatively homogeneous and land is used in similar ways without deliberate planning. Park and Burgess saw urban expansion as occurring through a series of "invasions" of successive zones or areas surrounding the center of the city. For example, people from rural areas and other societies "invaded" areas where housing was inexpensive. Those areas tended to be close to the places where they worked. In turn, people who could afford better housing and the cost of commuting "invaded" areas farther from the business district.  Paragraph 3 indicates that all of the following are true of "natural areas" as conceived by Park and Burgess EXCEPT:

Explanation

The passage states that natural areas are areas where the population is relatively homogeneous and land is used in similar ways without deliberate planning. It also mentions that urban expansion occurs through a series of "invasions" of successive zones surrounding the city center. Therefore, it can be inferred that natural areas are not usually protected from "invasion" by people in other areas. This is why the statement "Natural areas are usually protected from 'invasion' by people in other areas" is not true according to the passage.

Also, there are more extremes in western habitats. In the Sierra Nevada, high elevations are close to low elevations, at least in terms of mileage, but ecologically they are very different. The phrase "interspersed with" in the passage is closest in meaning to

Explanation

The phrase "interspersed with" in the passage means that tall mountains are distributed among vast areas of arid desert and grassland in the West. This suggests that the mountains are scattered or spread out throughout the region, rather than being concentrated in one area.

64. PARAGRAPH 4  Ecologists have studied the four chipmunk species that occur on the eastern slope of the Sierra and have learned just how these species interact while remaining separate, each occupying its own elevational zone.

The yellow pine chipmunk is common in low to mid-elevations and open to conifer forests, including piñon and ponderosa and Jeffrey pine forests. The lodgepole chipmunk is found at higher elevations, among the lodgepoles, firs, and high-elevation pines. The alpine chipmunk is higher still, venturing the talus slopes, alpine meadows, and high-elevation pines and junipers. Obviously, the ranges of each species overlap. Why don't sagebrush chipmunks move into the pine zones? Why don't alpine chipmunks move to lower elevations and share the conifer forests with lodgepole chipmunks?6) Which of the sentences below best expresses the essential information in the highlighted sentence in paragraph 4? Incorrect choices change the meaning in important ways or leave out essential information.

Explanation

The correct answer explains that ecologists have learned how chipmunk species on the eastern slope of the Sierra interact with each other while remaining separate. This suggests that the ecologists have studied the relationships and interactions between the chipmunk species in terms of their geographic distribution and elevational zones. The answer also implies that the ecologists have gained knowledge about how the chipmunk species separate and relate to each other in their respective habitats.

Explanation

The correct answer choices for the summary of the passage are: The model arose out of concern for the quality of life in the rapidly growing cities of early twentieth-century America, According to the model, a group new to the city tends to live together near the center and over time moves to outer areas that are more diverse ethnically and occupationally, and The model is applicable to cities that grow by attracting large numbers of workers to centrally located businesses. These choices accurately capture the main ideas of the passage, which include the purpose of the model, the pattern of residential movement, and the types of cities the model applies to.

68. (Paragraph 4)  Both humans and cetaceans have large brains with an expanded and distinctly folded surface, the cortex. The cortex is the dominant association center of the brain, where abilities such as memory and sensory perception are centered. Cetaceans have larger brains than ours, but the ratio of brain to body weight is higher in humans. Again, direct comparisons are misleading. In cetaceans it is mainly the portions of the brain associated with hearing and processing of sound information that are expanded. The enlarged portions of our brain deal largely with vision and hand-eye coordination. Cetaceans and humans almost certainly perceive the world in very different ways. Their world is one of sounds, ours one of sights. The word "dominant" in the passage is closest in meaning to:

Explanation

The word "dominant" in the passage is closest in meaning to "chief". This is because the passage is describing the cortex as the main or most important association center of the brain, where abilities such as memory and sensory perception are centered. Therefore, "dominant" refers to the central or primary role of the cortex in the brain.
