51. B Passage 1 is mostly interested in the geologic history of the Glen Canyon Dam, whereas
Passage 2 primarily discusses the use of controlled floods. Use POE to find the answer.
Eliminate (A); even though a problem is presented in Passage 1, Passage 2 doesn’t address
the same problem or solution. Choice (B) is a good fit, so keep it for now. Choice (C) is
pretty vague, and it’s not clear whether the changes in Passage 2 are recent, so eliminate it.
No experiment is discussed in Passage 1 with any specifics, so eliminate (D). Choice (B) is
correct.
52. D Use POE to find an answer that is applicable to both passages. Eliminate (A) and (B)
because neither passage discusses a scientific experiment or topographic changes. Choice
(C) is true of both passages, so eliminate it as well. This leaves (D), which is correct:
Passage 2 never discusses any specific species, whereas Passage 1 mentions the humpback
chub and Colorado pikeminnow.

And Justice for All
1. A If you can’t cite a reason to use a comma, don’t use one. In this case, commas are not
necessary because the fact that she works at the mall is important as a contrast to more
serious. Therefore, the answer is (A).
2. C The idea before the punctuation (She would start applying to law schools soon) is
complete. The idea after the comma and conjunction (she wanted to know what the law
looked like in action) is also complete. Remember the STOP punctuation rules. Choices
(A) and (D) can be eliminated because two complete ideas cannot be joined with just a
conjunction or just a comma; both are needed. The comma in (B) is in the wrong place, so
the answer is (C).
3. B Notice the question! It asks which statement is most in keeping with the main idea. The
passage centers on the Department of Corrections, and the only choice that introduces this
information is (B). The next sentence doesn’t even make sense without the specific
information in (B).
4. A Notice the question! It asks for a statement that reinforces ideas in this sentence as well as
the preceding sentence. The ideas in these sentences are about no one paying much attention
to the Department of Corrections. Choice (B) contradicts this idea. Choices (C) and (D)
contain the wrong focus. Therefore, (A) is the answer.
5. D The subject of this sentence is meaning, which is singular. Eliminate the choices with
plural verbs—(A), (B), and (C)—because they are inconsistent. The correct answer is (D).
6. D The underlined pronoun refers to Everyone, which is singular. Choice (D) is the only
possible answer because it is consistent in number.
7. D The sentence should come after another question about the treatment of inmates in order to
