PSAT Reading Question 32: Answer and Explanation

Question: 32

Which choice provides the best evidence for the answer to the previous question?

• A. Lines 1–5 ("Keio…in mice")
• B. Lines 18–20 ("Mice have…perception")
• C. Lines 33–35 ("After this…injection")
• D. Lines 35–38 ("As mice…paintings")

Correct Answer: D

Explanation:

D

The question is the best evidence question in a paired set. Because Q21 was a specific question, simply look at the lines used to answer the previous question. Two different lines were used in the prediction: Sensors recorded the staying time of mice in the compartments with their respective paintings and As mice know that morphine causes pleasure, they should stay longer near the painting associated with the morphine injection if able to discriminate between paintings. Of these two lines, only the second one is an answer choice. The correct answer is (D).
