PSAT Reading Question 591: Answer and Explanation

Question: 591

Which option gives the best evidence for the answer to the previous question?

• A. Lines 8–12 ("While the . . . culture")
• B. Lines 76–80 ("As the use . . . microorganisms")
• C. Lines 88–92 ("The most . . . patients")
• D. Lines 102–107 ("Instructions . . . dose")

Correct Answer: B

Explanation:

(B) Lines 76–80 speak of "growing concern" about the "development of antibiotic resistant organisms," which would be organisms not susceptible to current medical treatments. This matches the question's requirements. Lines 8–12 speak of the use of spices, and the author makes no mention of an opinion on these. Lines 88–92 describe MRSA, which is a large problem in the medical community. However, the mention of MRSA, alone, does not constitute sufficient evidence for the question. Lines 102–107 merely mention instructions for taking antibiotics, which also doesn't entirely satisfy the question's requirement of "a major concern" for the author.
