Act/SAT Questions Of The Day Test PrActice

1. Choose the word or set of words that, when inserted in the sentence, best fits the meaning of the sentence as a whole. The accident left Tom not so much incapacitated as -------: he was left weak, but the doctors gave him reason to expect -------.

Enfeebled . . progression

Inconvenienced . . deterioration

Frustrated . . enervation

Vindicated . . complication

Debilitated . . recovery

Choice (E) is correct. “Debilitated” refers to an often temporary loss of strength, less severe than becoming “incapacitated,” or deprived of strength or ability. Since the impairment is serious but temporary, doctors might very well encourage Tom to expect “recovery” after a period of convalescence.

The correct answer is C. A rule for divisibility by 3 is: if the sum of the digits of a number is divisible by 3, then so is the number; 4 + 4 + 8 + 2 = 18, which is divisible by 3.

3. If the experiments were repeated after pounding the stick farther into the ground so that only 0.5 m was exposed, how would this affect the shadow lengths?
Passage II
The Sun's path from sunrise to sunset varies with the time of year. A student performed the following experiments on three clear, sunny days at three- or four-month intervals throughout the course of a year to study the path of the Sun through the sky.
Experiment 1
At a chosen Northern Hemisphere location, the student placed a stick vertically into the ground so that 1 meter of its length was left above ground. The student knew that the length of the shadow was related to the height of the Sun above the horizon and that the shadow would point away from the direction of the Sun. The length in meters (m) and direction of the shadow cast by the stick were measured one hour after sunrise (Shadow A), at mid-morning (B), at noon (C), at mid-afternoon (D), and one hour before sunset (E) on each of the three days. The direction of each shadow was determined by placing a magnetic compass at the base of the stick and aligning the north arrow with the north mark on the compass. The direction of each shadow was then determined by a comparison with the compass face markings. The results are recorded in Table 1.

Table 1
Shadow	Day 1		Day 2		Day 3
Shadow	Length (m)	Shadow direction	Length (m)	Shadow direction	Length (m)	Shadow direction
A	5.0	SW	8.6	NW	6.8	W
B	1.2	W	2.9	NNW	1.7	NW
C	0.3	N	2.3	N	0.9	N
D	1.2	E	3.0	NNE	1.8	NE
E	5.0	SE	8.6	NE	6.9	E

Experiment 2
The following year, the student repeated Experiment 1 at a chosen location in the Southern Hemisphere. The results are in Table 2.

Table 2
Shadow	Day 1		Day 2		Day 3
Shadow	Length (m)	Shadow direction	Length (m)	Shadow direction	Length (m)	Shadow direction
A	9.0	SW	5.0	NW	6.9	W
B	3.2	SSW	1.1	W	1.8	SW
C	2.5	S	0.3	S	1.0	S
D	3.2	SSE	1.1	E	1.8	SE
E	9.1	SE	5.0	NE	6.9	E

They would be twice as long as those in the original experiments.

They would be one-and-one-half times as long as those in the original experiments.

They would be one-half as long as those in the original experiments.

They would be one-fourth as long as those in the original experiments.

Explanation: The correct answer is C. According to the experiments, the length of stick exposed above ground was related to the lengths of shadows measured.

4. The following sentence contains either a single error or no error at all. If the sentence contains an error, select the one underlined part that must be changed to make the sentence correct. If the sentence contains no error, select choice E. Cola nuts are the caffeine-rich nuts of Cola auminata and Cola nitida, evergreen forest trees that are native to (A) tropical West Africa and that are a member (B) of (C) the same botanical family as (D) cocas. No error (E)

(A)

(B)

(C)

(D)

(E)

Explanation: The error in this sentence occurs at (B), where there is noun-noun disagreement. The singular “a member” does not agree with the plural “trees.”

5.

She is often frustrated and short-tempered.

She can lip-read.

She dislikes conversation.

She is a shy and lonely woman.

Explanation: The best answer is B. The key is clearly supported by lines 16–18. All of the other foils are contradicted by the passage: C by line 22, and A and D by her personality as it is revealed over the course of the passage.

6. Was created to license stations, because it had no power to regulate them. Broadcasters multiplied wildly, some helping themselves to the more desirable frequencies, others increasing their transmission power at will. Chaos means things were out of control.

NO CHANGE

Since

Thus

But

Explanation: The best answer is J, which uses the coordinating conjunction but to logically connect the two clauses in the sentence. The other choices introduce defects in logic. Choices F and G (because and since, respectively) propose subordinating conjunctions that suggest a cause-effect relationship between the clauses that isn't supported by the essay. The use of the adverb thus in Choice H creates a comma splice as well as another logic problem: the creation of the federal Radio Division did not result in its lack of power to regulate.

7. Read the following SAT test question, then click on a button to select your answer. A right circular cylinder has height 6 and volume 54π. What is the circumference of its base?

2π

3π

6π

9π

18π

Explanation: The correct answer is C. The volume of a cylinder with radius r and height h is equal to πr2h. Therefore, πr2(6)=54π and r2=9, so the radius of the cylinder is 3. The circumference of a circle with radius r is equal to 2πr; therefore, the circumference of the base is equal to 6π.

Ostensibly

Intuitively

Sporadically

Unequivocally

Predominantly

Explanation: The answer is A. The fact that Andrea’s suspicions were “correct” indicates that Michael’s compliments were only “ostensibly,” or seemingly, sincere.
