Reading comprehension:

1. Answer: The correct answer is (C). The last sentence of the first paragraph sets forth this central theme. The paragraphs that follow give the relevant details.

2. Answer: The correct answer is (C). As paragraph two explains, the specialized cells “lose their identity and revert” to being unspecialized cells, forming a blastema. Only after this do they proliferate; so it’s wrong to say that the “specialized cells . . . proliferate rapidly,” as choice (C) does.

Sentence correction:

Answer: The correct answer is (B). Since Nixon was himself a former president, he is a member of the group with which he is being compared in the final part of the sentence. Therefore, the word “other” is essential to make the comparison logical.

Critical reasoning:

Answer: The correct answer is (A). Reread the last sentence of the passage. The author contends that Scopes should not have been tried for his “crime” because he “did not break the law on his own initiative.” The obvious implication is that a person whose crime is originally suggested by another should not be held responsible for that crime.

Math multiple choice:

Answer: The correct answer is (D). 817,380 is divisible by all the numbers in the list except 8. Hence, 8 must give the largest remainder because it is the only one that is not zero. To start, 7,380 is divisible by 5 because it ends in 0. It is divisible by 2 because it is even and by 4 because 80 is divisible by 4. However, it is not divisible by 8 because 380 isn’t. In addition, the sum of its digits is 27, which is divisible by 3 and by 9. Because it is divisible by both 2 and 3, it is also divisible by 6.

Data sufficiency:

Answer: The correct answer is (A). Statement (1) alone tells us more than we need to know. Simply knowing that the average of x and y is a whole number is enough to tell us that y is odd, since the only way for the average to be a whole number is for the sum of x and y to be even. Thus, if x is odd, so is y. Statement (2) alone is not sufficient. If y is odd, then y + 1 is even; and if y is even, then y + 1 is odd. In either case, x + y + (y + 1) is the sum of two odds and an even, which must be even. There are many even numbers that are divisible by 3, giving an integer for the average.
