Answer choices

  1. Both Presumably Agree9% picked this

    trampolines cause injuries to a significant number of people

    Although the 2nd person brings up considerations that make trampolines sound less alarmingly dangerous, he would still probably agree that a significant number of people are injured. He doesn't push back against the 83,000 injury fact.

  2. Too Strong: main source1% picked this

    home trampolines are the main source of

    We wouldn't be able to infer from either person's statements that home trampolines are the main source of trampoline injuries.

  3. No Comment from Person 14% picked this

    the rate of trampoline-related injuries, in terms of the number of injuries per trampoline

    We know that Person 2 would agree with this claim, but Person 1 doesn't have any statements that conflict with this.

  4. Too Strong: tends to17% picked this

    professional supervision of trampoline use tends to reduce the number of

    Person 1 would probably agree to this, since she is insisting on professional supervision. But we don't have a good conflicting idea from Person 2. He brought up the fact that injuries still occur, even if you have professional supervision, but that leaves room for him to agree that having supervision generally reduces the number of injuries.

  5. Correct69% picked this

    Why this is right

    We know Person 1 agrees, because that's her last claim. Person 2's disagreement is supportable by the fact that he downplayed the relative danger of trampolines and reminded us that injuries will happen with or without supervision. He seems to be suggesting that we need not worry quite so much as Person 1 is worrying, and that we need not always have professional supervision.

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