The correct answer is (D).
(D) Point at Issue
Step 1: Identify the Question Type
A question asking what two people "disagree" about is a Point at Issue question. Identify what both speakers address and where their opinions differ.
Step 2: Untangle the Stimulus
Taylor concludes that a specific claim, like all mathematically precise claims, is suspect because science cannot establish such exact claims.
Sandra, on the other hand, doesn't address the specific claim Taylor discusses. Instead, she asserts that precise claims need not always be doubted because some scientific disciplines can yield extremely precise results.
Step 3: Make a Prediction
The point of disagreement is about whether to doubt all precise scientific claims. If you do not recognize a point of disagreement, dive right into the answers, asking in turn whether each speaker has an opinion on the answer choice and whether those opinions conflict. Watch out for answers that mention topics that only one person addresses or on which they might actually agree.
Step 4: Evaluate the Answer Choices
(D) is correct. Taylor believes that all mathematically precise results are inherently suspect while Sandra believes that some sciences can yield precise results.
(A) is incorrect. While you know Taylor would be suspect of such results, Sandra doesn't mention this specific finding. You can't know whether Sandra would think this is one of those scientific disciplines for which she thinks precise results can be obtained.
(B) says the same thing as (A), only slightly stronger. Again, you do not know Sandra's beliefs regarding the possibility of precision in this particular scientific discipline.
(C) is wrong for the same reason the first two answer choices are. It is unknown whether the study of verbal and nonverbal communication is one of the fields of scientific study within which Sandra believes precise results are possible.
(E) is Out of Scope. While Taylor mentions inherently suspect claims, Sandra doesn't. Moreover, neither speaker addresses the falsity of scientific claims in general.
