Answer: Option C. -> The company requesting import relief has been injured by the sale of imports in the United States.
:
C
The best answer is C, which can be inferred from the case given in the 3rd paragraph.

Answer: Option C. -> Researchers found that some areas of the anteater’s snout were not sensitive to a weak electrical stimulus.
:
C
The best answer is C. In the experiment described in the first passage, researchers described the electroreceptors in the anteater’s snout as “clustered” at the tip. Thus, it can be inferred that nervous activity was not recorded across the entire snout, but only in certain areas. Therefore, some areas of the snout, including those containing the tactile receptors, were not stimulated by the weak fields used in the experiment, as choice C suggests.
There is no information in the description of the experiment provided in the passage to suggest A, B or D.

Answer: Option C. -> It crosses the Geminid meteor stream once every year.
:
C
This question asks you to draw an inference from information in the last paragraph of the passage. The best answer is C. According to the passage, the Geminid meteor shower occurs yearly; because meteor showers occur whenever the Earth passes through a meteor stream, one can infer that the Earth crosses the Geminid stream once every year. Choice A is incorrect because the passage provides no information from which to generalize about the age of meteor streams. Choice B, which is directly contradicted by the passage, is also incorrect. Choice D is incorrect. The passage says that the Earth would take just over a day to cross the stream if the stream were 5,000 years old. However, in the next few lines the passage states that in fact an average of only 19 hours elapsed between the time that the Earth entered the stream until the time that it exited, leading researchers to conclude that the stream is only about 3,000 years old.

Answer: Option C. -> It would have been more difficult for the Brotherhood to build its membership.
:
C
The best answer is C. The passage indicates that it was an advantage to Randolph in building the Brotherhood’s membership that Black workers shared “the same grievances from city to city”, suggesting that it would have been more difficult to build the membership of the Brotherhood if Black workers in different parts of the country had had different grievances.
There is no information in the passage to support A, B and D.

Answer: Option B. -> The structural relationship between caffeine and adenosine
:
B
B is the best answer. This question asks you to identify information that is suggested rather than directly stated in the passage. To answer it, first look for the location in the passage of the information specified in the question. The A1 and A2 receptors are mentioned in lines 23-26. Lines 27-35 go on to describe Snyder et al's hypothesis about the effects of caffeine on behavior. They propose that caffeine, “which is structurally similar to adenosine,” is able to bind to A1 and A2 receptors in the brain, the same receptors that adenosine normally binds to. Thus, the passage suggests that the structural relationship between caffeine and adenosine may be partially responsible for caffeine's ability to bind to A1 and A2 receptors.

Answer: Option B. -> satirical
:
B
Option (b)
The writer is using satire to mildly tease the French winemaker.

Answer: Option B. -> present the central thesis of a recent book
:
B
B is the best answer.
In the first paragraph, the author contrasts two incidents that are said to exemplify the transformation in social values that forms the subject ofZelizer’s book. The second and third paragraphs consist of a brief history of that transformation, as Zelizer presents it, and an account of the factors she considers important in bringing it about. In the last paragraph, the author explains how Zelizer’s thesis differs from that of sociological economists. Thus, the passage serves primarily to present the central thesis of Zelizer’s book. Amisrepresent the subject matter of the passage. D misrepresents the author’s approach. C is incorrect because although the passage does contrast two approaches, this contrast takes place only in the final paragraph.

Answer: Option D. -> emphasizing the development of methods for the mass production and distribution of a new technology.
:
D
The best answer is D. The passage sets up a contrast with “traditional” ways to benefit from marketing a product by stating that market place success based on leadership in “mass production and distribution” is characteristic of today’s companies, not those of the past.
Choice B is incorrect because it describes the way in which companies have achieved success in the past.
Choices A and C are incorrect: they present ways of earning profits that are not discussed in the passage.

Answer: Option A. -> eliminate and alternative explanation of anteaters’ response to electrical stimuli.
:
A
The best answer is A. Because tactile receptors also respond to electrical stimulation, the researchers’ conclusion that electroreceptors exist is valid only if it can be demonstrated that the nervous activity recorded in the anteater’s brain did not originate in the tactile receptors.
There is no indication in the passage that tactile receptors function like electroreceptors (B) or that tactile receptors assist electroreceptors (D).
There is no information in the passage to suggest that the presence of tactile receptors complicated research onelectroreceptors, so (C) is not correct.

Answer: Option A. -> Meteor activity would gradually increase to a single, intense peak, and then gradually decline.
:
A
The best answer is option A.
(A) This is stated in the passage"Conventional theories, however, predicted that the distribution of particles would beincreasingly dense toward the center of a meteor stream.
Choice B is exactly opposite of A. Choice C is not true from the context of the passage. Choice D is not mentioned in the passage.
