Stimulus

Physician: In order to investigate diseases caused by hormonal imbalances, a certain researcher wants to study, among others, 200 children whose pituitary glands fail to produce typical amounts of Human Growth Hormone (HGH). The study would involve administering a synthetic version of HGH to the children over a two-year period. But medical only a minimal risk to the subjects. The researcher’s proposed study should be prohibited.

What this question is testing

Your task

Find the choice that makes the argument's conclusion more likely to be true.

Common trap

Answers that are consistent with the argument but add no real support, or that strengthen a claim the argument doesn't make.

Winning move

Locate the gap between evidence and conclusion, then pick the choice that closes it.

Which one of the following, if true, would most help to justify

Answer choices

  1. Unrelated to Goal2% picked this

    The resources expended on the HGH study could be spent instead on research likely to lead to treatments for medical conditions more serious

    This answer isn't telling us either of the two things we're looking for (unlikely to reveal helpful stuff about medical condition / unknown whether poses only minimal risk). This answer would strengthen the idea of "Let's not do this proposed study; let's spend money on something else instead", but it has no strengthening effect on the idea of "This proposed study should be prohibited." There's a big difference between saying "You shouldn't waste your money on that" and "You're not allowed to spend your money on that".

  2. Opposite4% picked this

    About 10,000 children have already been given synthetic HGH without obvious

    One of the two things we're looking for that would justify this conclusion is that "it's unknown whether this treatment poses only minimal risk". This answer goes in the opposite direction, giving us a robust sample of children who are experiencing minimal risk. This answer would strengthen the idea of "Let's not do this proposed study; let's spend money on something else instead", but it has no strengthening effect on the idea of "This proposed study should be prohibited." There's a big difference between saying "You shouldn't waste your money on that" and "You're not allowed to spend your money on that".

  3. Unrelated to Goal2% picked this

    Obtaining informed consent from children is impossible, because they are not yet mature enough to

    "Consent" is out of scope. We can't invent our own rule of "If the subject can't give consent, then the research should be prohibited". We need an answer to trigger the provided rule: unlikely to reveal helpful stuff about medical condition or unknown whether poses only minimal risk

  4. Too Weak22% picked this

    Although hormonal imbalances can cause disease, the imbalances themselves do not constitute

    This almost establishes that "doing this research is unlikely to reveal important information about a medical condition", but not quite. We don't have to believe that the only medical condition we could learn about by giving HGH to kids is the 'hormonal imbalances' (which, this answer tells us, not a medical condition). It could be that the hormonal imbalances these kids have don't necessarily come from the same underlying root condition. Maybe giving them synthetic HGH while taking into account other differences we know about them would reveal important information. Perhaps one of them has low HGH because of a certain auto-immune disease, and when we give that kid HGH the kids' fevers and body aches disappear. That would be important information about that auto-immune disease. So the fact that hormonal imbalances aren't themselves a medical condition doesn't quite establish that doing this research is unlikely to give us some important info about something that is a medical condition.

  5. Correct70% picked this

    The long-term effects of synthetic HGH have never been tested and

    Why this is right

    This establishes the 2nd of the two things we were hunting for. unlikely to reveal helpful stuff about medical condition or unknown whether poses only minimal risk Since we had a rule that said "medical research is permitted only if it's known to pose a minimal risk", then saying "the long-term effects of this medical research have never been tested and are unknown" would violate that necessary requirement. Hence, the author would be right to say the study should be prohibited.

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