Stimulus Summary

Classes with too many students and teachers with too many classes are bad for a university, so it’s bad for a university to have too large/small classes and teaching loads.

Answer Anticipation

Notice anything about the premise compared to the conclusion here? The conclusion is about class sizes that are too big or too small, and teaching loads that are too heavy or too light. However, the premise is about “crowded” classes and “overworked” teachers. That only addresses half of the conclusion!
As such, we should look for an answer that brings up a similar problem for the university that comes from having class sizes that are too small or teachers with too few classes.

Answer choices

  1. A
    Professors who have very Remaining source text redacted.
    Why choice A is not credited
    If anything, being able to focus on research sounds like an upside of having professors without heavy teaching loads, so this would weaken that part of the conclusion.
  2. B
    Classes that have very Remaining source text redacted.
    Why choice B is not credited
    A lot of classroom discussion sounds like a benefit of small class sizes, not a downside.
  3. C
    Very small class sizes Remaining source text redacted.
    Why choice C matches the stem
    Small classes and teaching loads demonstrate bad teaching? That’s a downside of those things, which supports the conclusion, making this the correct answer.
  4. D
    Very small class sizes Remaining source text redacted.
    Why choice D is not credited
    If they’re common in the worst and the best universities, then the small class sizes and teaching loads aren’t inherently bad, and so this answer doesn’t strengthen the argument that they are.
  5. E
    Professors with very light Remaining source text redacted.
    Why choice E is not credited
    This answer establishes that light teaching loads don't have a benefit over normal teaching loads, but it also doesn’t say that it has a downside over them, so this answer doesn’t really affect the argument.
