PrepTest 112, Section 2, Question 1

Working the answers

• A

  This emphasizes the advocates' case for effective substitution. The writer accepts some of the benefits, then explains why conferences still fall short. A leaves out that central objection.

• B

  We aren't told that people are returning to traditional interactions. The ending worries that they might cut themselves off further from their neighbors, not that they are already reversing that trend.

• C

  The writer grants that conferences can be respectful and supportive. Geographic separation and typing aren't presented as preventing those benefits; the objection is that those benefits aren't enough.

• D
  Correct

  My initial prediction didn't give diversity this much emphasis, so this may seem too narrow at first. But look at the reasons in the final paragraph: costs and computer knowledge restrict access, and selection around a topic produces a less varied group. Diversity is the main reason these conferences fall short. D combines that reason with the conceded benefits, sharpening our initial prediction.

• E

  This goes beyond the conferences described to a hypothetical in which broader access attracts more diverse participants. The writer doesn't assess whether conferences would remain inadequate under those changed conditions. A conclusion about their present limitations doesn't by itself settle that further question.
