Logical reasoning PrepTest 130 · Section 1 · Question 10

Incorrect. While the Historian found that unrepresentative, concise bebop recordings were superb artistic works, that doesn't mean the non-concise live performances weren't—that's an illegal negation.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Poor postwar studios recorded shorter bebop solos than what was performed live. However, these recordings are valuable art in their own right, and the shortness positively affected the live shows in a way absent from future musicians.

Answer Anticipation:
The statements here make some comparisons between: live bebop and recordings; postwar bebop and later bebop; live shows before the short recordings and after. There aren't a lot of statements that overlap, though, and no conditionals, so the correct answer is likely to either infer from one of these comparisons, or draw a generalization from the information provided. There isn't a great anticipation here, so we should instead head to the answers as soon as possible.

Answer Explanation:
This answer is a generalization of the information in the stimulus. The Historian notes that the requirements to be concise created "superb" recordings that made it into their live performances, so those difficult conditions that made being concise necessary did have some benefits.

Key Takeaway:
When there aren't conditional statements or clear connections between statements in a Must Be True question, it's usually best to get a solid understanding of the stimulus and then head to the answers as soon as possible to spend your time analyzing and eliminating. Additionally, when the stimulus doesn't lend itself to clear inferences through combining statements, correct answers tend to be generalizations of the situation described in the stimulus.

Incorrect. This answer is too extreme. While the Historian does believe that the concise recordings are superb artistic works, there could be some duds out there, or some similarly superb longer recordings that leave most short ones in the dust.

Incorrect. While the next generation lacked the compactness of the early bebop musicians, the Historian never discusses their overall quality. They may be missing one feature that led to some superb recordings, but they could have many other features that more than make up for that shortcoming.

Incorrect. First, in talking about musicians instead of early bebop musicians, this answer choice is too broad. Second, while the argument does establish that difficult recording conditions led early bebop musicians to record the short solos, it doesn't establish that other conditions couldn't have led them to do the same.
