Logical reasoning PrepTest 124 · Section 3 · Question 21

Incorrect. The stimulus doesn't discuss the decision process and available options when the waste was first stored at the current location. While the argument does establish that the current location poses significant risks, it might have been the best option at the time it was initially placed there.

Incorrect. The stimulus strongly suggests that the waste should be moved sooner rather than later, so waiting for the most secure location that can "ever" be found is, if anything, contradicted.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
It's extremely unlikely the proposed waste site will fail to contain the waste. Leaving it where it is poses unacceptable risks, and finding a completely safe site could take years.

Answer Anticipation:
The current site sounds bad—in fact, it's noted that leaving the waste at the current site for years is "unacceptable." The new site sounds...better than the old site, but not perfect.

Other than that implicit comparison between the two sites, the correct answer could derive from any of the statements, so let's head into the answers and stay flexible.

Answer Explanation:
The stimulus notes that keeping the waste at the current location and failing to move it until a completely safe site is found poses "unacceptable" risks. The entire stimulus is designed to present information against the objection to the proposed site based on these risks, so it is very strongly supported that the new site reduces those risks.

Key Takeaway:
Don't get too wrapped up in forcing an anticipation in Must Be True questions—especially Most Strongly Supported ones—if nothing seems obvious to you. Many of the answers are less predictable, and so it's more important to allow yourself time to look through the answers than to have a rock solid idea of what you're looking for.

Incorrect. The stimulus discusses one particular case, so this answer about "[w]henever waste must be moved" is too broad.

Incorrect. The middle of a school would probably not be a safe place to store the hazardous waste. This answer is too extreme in stating anywhere is safer.
