LSAT 141 | Section 1 | Reading Comprehension: Q4

RC Question 4 Explanation

DISCUSSION: As usual, the right answer is stated in the passage. The wrong answers contradict the passage or quote familiar words out of context.

Questions like this reward your ability to retain details or know where they were mentioned. The better you know the passage, the more the wrong answers will appear obviously wrong.

After reading the passage, I always skim it before starting. This lets me see all text at least twice, and I retain significantly more detail.

___________

1. This is far too strong. The author’s point was only that natural selection is not responsible for all changes.
2. CORRECT. Paragraph 4 says this. We mammals flourished after the asteroid strike 65 million years ago, even though we had not been adapted to our environment.
3. This contradicts lines 29-31: most changes have no advantage or disadvantage.
4. Lines 43-45 say that large animals have difficulty surviving “catastrophic” conditions. But that’s not the same thing as “harsh” conditions. The arctic or a desert are harsh environments, but they’re not “catastrophic”.
5. Line 11 mentions form and behavior. It doesn’t distinguish between the two ideas. This answer is trying to fool you by mentioning words you might remember from the passage, out of context.
