Question Type

Must Be True Questions

Answer Anticipation

This stimulus has two common types of logic in Must be True questions.
First, there are some causal statements. The electric instruments allow people to play louder, resulting in fewer musicians per band. They have also increased the overall number of professional musicians.
Second, tied to the language in the first, are comparisons. The electrical instruments decreased the number of musicians per band but increased the total number of musicians.
The correct answer will likely work with these statements/ideas.

Answer choices

  1. A
    The number of amateur Remaining source text redacted.
    Why choice A is not credited
    The stimulus discusses only the number of musicians playing “professionally,” so amateurs are out of scope.
  2. B
    Most professional musicians are Remaining source text redacted.
    Why choice B is not credited
    There’s no discussion of anything true of “most” professional musicians, so this answer is unsupported.
  3. C
    The number of professional Remaining source text redacted.
    Why choice C is not credited
    While possible since the argument talks only about the “average” per band, it’s also possible that every band now has fewer musicians. The average usually doesn’t let us draw any determination about individuals making up that average.
  4. D
    The total number of Remaining source text redacted.
    Why choice D matches the stem
    If there are fewer musicians per band but more musicians overall, then there must be more bands.
  5. E
    Many professional musicians play Remaining source text redacted.
    Why choice E is not credited
    There’s no discussion of multi-band musicians.
