LSAT Question Complete Explanation

First, let's break down the passage. McKinley states that a double-blind study is the most effective procedure for testing the efficacy of a drug. However, he believes that they cannot perform such a study on the new drug because its various effects on patients' bodies will reveal whether they are receiving the drug or a placebo. Engle disagrees with McKinley's conclusion, arguing that McKinley is assuming he knows the outcome of the study.

The question type for this problem is "Misc." It asks us to identify how Engle is most likely interpreting McKinley's remarks.

Now, let's analyze the answer choices:

a) McKinley never states that a double-blind study is the only effective way to test new drugs, just that it is the most effective procedure. Engle's statement does not imply that he interpreted McKinley's remarks this way.

b) Engle's statement does not indicate that McKinley is denying the drug's effectiveness. McKinley is concerned about the various effects of the drug making it impossible to conduct a double-blind study, but this does not imply that he believes the drug is ineffective.

c) Engle's statement does not suggest that McKinley is presuming that the placebo will produce no effects on the patients' bodies. McKinley is concerned about the various effects of the drug, not the absence of effects from the placebo.

d) Correct answer. Engle's statement indicates that he is interpreting McKinley's remarks to be referring to the drug's therapeutic effects rather than any known side effects. If McKinley was only considering the drug's intended effects, his argument would assume that the drug is effective before the study has been conducted. However, if McKinley was considering both the intended therapeutic effects and the known side effects, Engle's challenge would be less relevant.

e) Engle's statement does not suggest that McKinley is confused about when a drug is efficacious. McKinley is concerned about the various effects of the drug making it impossible to conduct a double-blind study, not about the definition of an efficacious drug.

In summary, Engle's statement indicates that he is most likely interpreting McKinley's remarks to be referring to the drug's therapeutic effects rather than any known side effects.
