Answer choices

  1. Weakens7% picked this

    People spend as much time watching television today as people spent listening to radio

    If television provides even a small opportunity to exercise one's imagination, this could make it possible that today's generation exercise their imaginations as much or more than earlier generations.

  2. Too Strong3% picked this

    The more familiar a form of popular entertainment becomes, the less likely its consumers are

    This is a relative relationship that the argument does not require. The argument never actually addressed how familiar each form of popular entertainment was before or is today.

  3. Out of Scope2% picked this

    Because it inhibits the development of creativity, television is a particularly undesirable form

    The desirability of a form of entertainment is not relevant to the argument.

  4. Correct53% picked this

    For today's generation of television viewers, nothing fills the gap left by radio as a medium

    Why this is right

    This defends the argument from a possibility that would destroy the argument's reasoning. If something did fill the gap left by radio, then today's generation would not necessarily exercise their imaginations less frequently.

    Skill tested: Necessary Assumption · how this choice captures the argument's function is the move to repeat next time.

  5. Too Strong35% picked this

    Television drama does not require its viewers to think about what

    It's too strong to say that viewers don't have to think about what they see when they watch TV drama. The salient comparison in the argument is about imaginative thinking. Radio forces you to think about what a scene or character looks like. You have to imagine what it looks like. With TV, you don't have to imagine what it looks like, but you still might have to think. After all, you still have to process dialogue. You might think about what's coming next in the story. You might have to think about information you learned in past episodes. If this answer said, "TV drama does not require its viewers to do as much imaginative thinking as radio does", it would be fine.
