PSAT Writing and Language Question 478: Answer and Explanation

Question: 478

• A. NO CHANGE
• B. biological engineering to veterinary medicine.
• C. engineering of the biological variety and medicine of the veterinary type.
• D. veterinarians doing medicine and biologists engineering.

Correct Answer: B

Explanation:

(B) Notice the parallelism of the sentence, specifically in the recurring reference of the word "to." Choice (A) breaks with that pattern by swapping "to" for "with." Choice (D) also breaks with the pattern by omitting "to." Choice (C) is wordy. Choice (B), "biological engineering to veterinary medicine," maintains our desired parallelism.
