●Question 2. Critical Reasoning
Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600’s areremarkably complete. This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines.Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was computed by the central government using the annual census figures. Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village’s population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen.
In the historian’s argument, the two portions in boldface play which of the following roles?
A. The first supplies a context for the historian’s argument; the second acknowledges a consideration that has been used to argue against the position the historian seeks to establish.
B. The first presents evidence to support the position that the historian seeks to establish; the second acknowledges a consideration that has been used to argue against that position.
C. The first provides a context for certain evidence that supports the position that the historian seeks to establish; the second is that position.
D. The first is a position for which the historian argues; the second is an assumption that serves as the basis of that argument.
E. The first is an assumption that the historian explicitly makes in arguing for a certain position; the second acknowledges a consideration that calls that assumption into question.
●Question 3. Data Sufficiency
Directions: In this problem, a question is followed by two statements containing certain data. You are to determine whether the data provided by the statements are sufficient to answer the question. Choose the correct answer based upon the statement’s data and your knowledge of mathematics.
If x, y are integers, is (x^3)y an even number?
1) x+y is odd number.
2) xy is even number.
A. statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question
B. statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question
C. both statements taken together are sufficient to answer the question, but neither statement alone is sufficient
D. each statement alone is sufficient
E. statements 1 and 2 together are not sufficient, and additional data is needed to answer the question
●Answer to Q1: D
In terms of the idiom, the verb “demand” is followed by a noun, that-clause, or to-infinitive. Therefore, the answer choices B and E are the unidiomatic structures. In addition, “should” in the answer choice A results in redundancy because the participle “demanding” itself has the meaning of “should.” And the answer choice C is also using a redundant expression “yielded to thousands of irate consumers and their demand.” So, the answer is D.
●Answer to Q2: C
Boldface questions typically ask for the function of two highlighted phrases. For any Critical Reasoning questions, the very first step a test-taker should take is to figure out what is the author’s conclusion in the argument. The easiest way to identify a conclusion is through signal words, such as therefore or thus. In this question, the author’s conclusion is that “the reported declines in populations did not actually happen.” The only answer choice that correctly explains the role of the second portion of the boldface is C.
●Answer to Q3: D
Condition 1) Because x+y is odd number, one of x and y is even number, the other is odd number. So this condition is sufficient to answer the question.
Condition 2) Because xy is even number, (x^3)y=(x^2)xy=(x^2)even=even. So this condition is sufficient to answer the question. Therefore the correct answer is D.
