Method of Reasoning. The correct answer choice is (B)
The argument notes that lawmakers are considering a proposal requiring milk labels to provide
information about what artifi cial substances were used in the production of the milk. The conclusion
of the argument is that “the proposal should not be implemented,” because it would be unimaginably
diffi cult to list every artifi cial substance that went into the process of producing milk.
Since you are asked to identify the method of reasoning, remember to avoid responses that do not
pass the Fact Test (that is, responses that describe an event that did not occur in the stimulus).
Answer choice (A): The author proposes no “alternative course of action,” so this response is
Answer choice (B): This is the correct answer choice. The author does argue against the proposal,
and the proposal does lead to absurd consequences because identifying all the substances involved
could be tremendously diffi cult and listing the known substances would probably be impossible to fi t
onto a milk label.
Answer choice (C): The author does not offer any alternatives to the proposal.
Answer choice (D): This was the most popular incorrect answer. The key to eliminating this response
is to rigorously examine each part of the answer. Many students accept the portion that refers
to the analogous case because they believe that the references to fertilizer and fungicide qualify
as analogous cases. But, examine those cases closely—they are not analogous cases but rather
implications of the proposal regarding milk production (a qualifying analogy would likely have
involved discussing a different animal or a different product than the ones the proposal covered.).
Because the author did not make an analogous case, this choice is wrong.
Answer choice (E): This answer attempts to state that the author makes a source argument. The
author never questions the motives of those making the proposal, only the ultimate logical and
practical implications of the proposal.
