Question 22 Question 23 Question 24 Question 25 Question 26

McKinley argues that, because the new drug will produce a visible effect in those who take it, it won't be possible to use a double-blind study to determine the drug's efficacy.

Engle counters by saying that McKinley assumes what result the study will yield. However, McKinley doesn't make any claim about what the outcome will be—only that the test can't be conducted blindly because the drug produces some visible effects.

Engle appears to think that when McKinley refers to the “various effects” of the drug, he’s referring to the drug’s intended effects (efficacy), when in fact, McKinley is merely referring to its visible ones.

Engle isn’t commenting on whether there are other ways to study a drug. Rather, Engle just says that we can’t know whether a double-blind study will be possible in this case.

Engle accuses McKinley of assuming the outcome of the study, but doesn’t specify whether he thinks McKinley assumes the drug will be effective or ineffective.

McKinley doesn’t assume this; he merely states that the drug will produce effects. And Engle doesn’t suggest that McKinley makes any assumptions about the placebo’s effects, either. For (C) to have any support, Engle would have to raise the possibility that the placebo will have effects. But Engle doesn’t do this.

Engle accuses McKinley of assuming the “outcome” of the study—a study designed to test the drug’s therapeutic (curative) effects. So Engle thinks that when McKinley talks about the drug’s “various effects,” he’s referring to its therapeutic effects. But McKinley is just referring to visible effects, which could be side effects.

Engle’s concern is that McKinley can’t assume whether this one drug will be efficacious. Neither he nor McKinley are concerned with the general criteria for when a drug can be called efficacious.
