Logical reasoning PrepTest 142 · Section 4 · Question 13

Incorrect. The Mayor notes that neighborhoods that have excessive dirt due to major construction are qualified. That doesn't mean every neighborhood with construction qualifies—they'd have to have major construction resulting in excessive dirt.

Incorrect. The stimulus notes that those who request an interim sweeping will receive it immediately. It's not established that every qualified neighborhood will request an interim sweeping, so this answer isn't supported.

Incorrect. The Mayor doesn't limit interim sweepings to qualified neighborhoods—she just guarantees that qualified neighborhoods will have interim sweeping requests granted. There could be, for instance, a unique circumstance that would allow a non-qualifying street to get an interim sweeping.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Street in town → Swept at least 1/mo
Some things will qualify a neighborhood for interim sweepings
Request for interim sweeping from qualified neighborhood → Immediately satisfied

Answer Anticipation:
These statements don't easily chain together, but they do set up a clear set of rules for how sweepings are going to work in this city. While Must Be True questions don't always use all the statements from the stimulus in justifying the correct answer, many do—especially when an inference is possible that uses each statement.

Here, we know that a qualifying neighborhood that requests an interim sweeping will have it granted immediately. We also know that they're receiving a sweeping once/month as a matter of course. Thus, these neighborhoods—if an interim sweeping is requested—will be swept more than once/month. While this isn't the only potential answer, it does bring the whole stimulus together, so we should be on the lookout for it in particular.

Answer Explanation:
This answer brings together all the statements from the stimulus. If a qualified neighborhood requests an interim cleaning, it will receive one on top of the regular cleaning, thus receiving a cleaning more than once/month.

Key Takeaway:
Must Be True questions don't require correct answers to use all statements from the stimulus, but they frequently do—especially when there's an inference that can be made by combining all of the statements. If you see an inference that can be drawn from bringing all statements from the stimulus together, be on the lookout for it in the answers!

Incorrect. Similar to (C), the Mayor sets up a rule guaranteeing qualifying neighborhoods can receive interim cleanings, but that doesn't preclude non-qualifying neighborhoods from receiving an interim cleaning.
