PSAT Writing and Language Question 505: Answer and Explanation

Question: 505

  • A. NO CHANGE
  • B. swelling
  • C. to swell
  • D. swellingness

Correct Answer: B

Explanation:

(B) "Swelling" operates as a noun in this case, as gerunds can do under certain circumstances. Having the word in noun form makes it parallel to the rest of the sentence, unlike choices (A) and (C). Choice (D), "swellingness," is not a word.
