Onderdonk recruited Chinese workers to build the CPR because there were not enough workers in Canada and the CPR could save money by paying the Chinese workers lower wages than others. This is supported by the statement in selection 1 that there was a shortage of workers in Canada and that Chinese workers were paid lower wages compared to other workers. However, there is no mention of the Chinese workers having experience building railroads in their home country, so statement 3 is not included in the correct answer.

The explanation for the given correct answer is that paragraph 1 of the passage discusses the reasons why the CPR hired Chinese workers. It implies that there were various factors that led to the decision of hiring Chinese workers, without specifying those reasons. Therefore, the best summary of paragraph 1 would be "For different reasons, the CPR hired Chinese workers."

The correct answer is that Onderdonk would have hired more Canadian workers if they had agreed to work for less money. This implies that cost was a determining factor in Onderdonk's decision to hire Chinese workers instead of Canadian workers. If the Canadian workers had been willing to work for a lower wage, it would have been more cost-effective for Onderdonk to hire them, leading to the possibility of him hiring more Canadian workers.

From the given passage, it is mentioned that Canada was a colony of Britain until 1867 and was not politically independent. Therefore, we can infer that Hong Kong, being under British control, was also not independent during that time.

The writer assumes that the reader knows that the CPR refers to a railroad company because the passage mentions Chinese workers working on the CPR. This implies that the CPR is a known entity, and the assumption is made that the reader is aware that it is a railroad company.

The passage suggests that the Chinese workers were valued less than the other workers. This can be inferred from the information provided in the passage, which implies that the Chinese workers were subjected to harsh working conditions, discrimination, and unequal treatment compared to other workers.

The passage suggests that the CPR valued profit. This can be inferred from the fact that the Chinese workers were paid lower wages compared to their white counterparts, indicating that the CPR prioritized maximizing their profits by exploiting cheap labor.

The passage provides information that suggests that the Chinese workers faced difficulties or hardships while working in Canada. It does not mention anything about their love for fish, their preference for traveling by ship, or whether the CPR has honored the workers who lost their lives. Therefore, based on the information given, the conclusion that can be reached is that the Chinese workers experienced hardship in Canada.

The best title for the article would be "Volcanoes: a Hidden Danger" because the article likely discusses the potential dangers and risks associated with volcanoes. This title suggests that the article will provide information about the hidden dangers that volcanoes pose, which could include eruptions, lava flows, ash clouds, and other hazards.

Temperatures dropping over a long period of time can cause another Ice Age. During an Ice Age, the Earth's climate becomes significantly colder, leading to the expansion of ice sheets and glaciers. This occurs when there is a long-term decrease in global temperatures, which can be caused by various factors such as changes in solar radiation, shifts in ocean currents, or changes in the composition of the atmosphere. As temperatures drop, ice accumulates and reflects more sunlight, further cooling the planet and perpetuating the Ice Age conditions.

During an eruption, the first effects that are seen are usually the lava and steam. Lava is the molten rock that is expelled from the volcano and flows down its slopes, while steam is produced when the hot lava comes into contact with water or moisture in the surrounding environment. These two elements are typically the most visible and immediate signs of an eruption, as they can cause destruction and pose a threat to nearby communities and infrastructure. The other options listed, such as smoke and floods, fire and mudslides, and clouds and cool temperatures, may occur later in the eruption process or as secondary effects.

The correct answer is "Temperatures dropped considerably". This means that before the clouds from Mount Katmai disappeared, there was a significant decrease in temperatures. This could have resulted in various changes in the environment and weather conditions. It is important to note that the other options, such as an Ice Age beginning or heavy rains occurring, are not supported by the given information and are therefore not the correct answer.

The word "picture" in paragraph 1 is used to mean "imagine." This implies that the word is being used to suggest creating a mental image or visualizing something in one's mind. It does not refer to a physical frame, a discussion, or a photograph.

The cooling period after the eruption of Mount Katmai was too short to cause an Ice Age. This means that the decrease in temperature caused by the eruption and the resulting clouds was not sustained for a long enough period of time to have a significant impact on global climate.

The expression "no quiet place" refers to a location where one can be alone and have peace and tranquility. This suggests that the place mentioned does not offer an environment suitable for solitude and reflection. It implies that there is noise or disturbance in that particular place, making it unsuitable for finding solitude.

The correct answer is "shortage of food". This suggests that famine in the country is caused by a lack of food availability. This could be due to various factors such as crop damage, which can lead to a decrease in food production. The shortage of food can result in poverty and poor living conditions for the population, as they struggle to access enough food to meet their basic needs.
