Greta Harris: Went to a prestigious business school
Therefore - Greta Harris is a CEO making $250k+

Answer Anticipation

While the argument doesn’t use purely conditional language, it still presents a relationship that approaches a conditional statement, and then uses the “necessary”condition to justify the “sufficient” condition. As such, we should look for an answer that has a similar illegal reversal while not being a purely conditional statement.

Answer choices

  1. A
    Many opera singers are Remaining source text redacted.
    Why choice A is not credited
    This answer brings in a new concept in the conclusion - the health problems associated with being high-strung. The stimulus doesn’t introduce new concepts in the conclusion, so this answer is incorrect.
  2. B
    The most famous opera Remaining source text redacted.
    Why choice B is not credited
    This answer assumes a proportional relationship between practice and fame - that’s not an illegal reversal.
  3. C
    Many of the most Remaining source text redacted.
    Why choice C is not credited
    The conclusion here introduces a new concept - enjoyment. To be parallel, this answer would need to bring up an Italian person and conclude that they were an opera singer!
  4. D
    Quite a few opera Remaining source text redacted.
    Why choice D is not credited
    This argument establishes that George falls into the “sufficient” condition of the first statement, not the necessary one, so it doesn’t feature an illegal reversal.
  5. E
    A great many successful Remaining source text redacted.
    Why choice E matches the stem
    This answer establishes that a “great many” successful opera singers studied more than one language. It then finds someone who meets that “necessary” condition - studying more than one language - and concludes that they must be a successful opera singer. That’s the same reversal as the stimulus, so this is the correct answer.
