Stimulus

Roxanne: To protect declining elephant herds from poachers seeking to obtain ivory, people concerned about such endangered species should buy no new ivory. The new ivory and old ivory markets are entirely independent, however, so purchasing antique ivory provides no incentive to poachers to obtain more new least 75 years old-can be bought in good conscience.

Salvador: Since current demand for antique ivory exceeds the supply, many people who are unconcerned about endangered species but would prefer to buy antique ivory are buying new ivory instead. People sharing your concern about endangered species, therefore, should ensuring that demand for new ivory will drop.

A point on which Roxanne’s and Salvador’s views differ

Answer choices

  1. Unsupported for Both1% picked this

    there are substances that can serve as satisfactory substitutes for ivory in

    We couldn't derive that either person agrees or disagrees with this claim, since neither person really talked about suitable substitutes.

  2. Correct60% picked this

    decreased demand for antique ivory would cause a decrease in demand

    Why this is right

    This deals with claim 2, whether the antique and new ivory markets are entirely independent. Roxanne would disagree with this answer, since she said the new ivory and old ivory markets are entirely independent. Salvador would agree with this answer, since he is saying that if people who are worried about elephants cease buying ivory altogether, then people who are inclined to buy antique but not resolved to do so will be more likely to buy antique / less likely to buy new ivory. He thinks that if we elephant-lovers refrained from buying any ivory at all (including antique ivory), that demand for new ivory will drop.

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

  3. Disagree Position Unsupported1% picked this

    people should take steps to avert a threat to the continued existence

    It seems likely that both of these people would agree to this answer. They disagree about which steps should be taken, but they both seem to think concerned people should take steps. We can't derive from either paragraph the Disagree position: "People shouldn't take any steps to avert a threat to the existence of elephants"

  4. Disagree Position Unsupported15% picked this

    a widespread refusal to buy new ivory will have a substantial effect on the

    It seems likely that both of these people would agree to this answer. They're both suggesting behavior that they think will lessen the demand for new ivory, and thus will lessen the incentives for poachers to kill elephants. We can't derive from either paragraph the Disagree position: "A widespread refusal to buy new ivory will not have any substantial effect on the survival of elephants."

    Out of Scope 2nd Speaker: 75 years old Salvador never addresses Roxanne's 3rd claim about the 75 year conscience cut-off, so we can't derive any sense of how he feels about this. More than likely, both speakers would agree that if you're worried about elephants, you shouldn't be buying recent ivory.
