Digital PSAT Reading and Writing Practice Question 255: Answer and Explanation

Question: 255

Allergens, pollution, bacteria, and sunlight—these are just some of the foreign objects that _______________________

Which choice completes the text so that it conforms to the conventions of Standard English?

  • A. on a basis that is daily are attacking the human body.
  • B. attacking the bodies of humans on a daily basis.
  • C. attack the human body on a daily basis.
  • D. attacks humans each and every day.

Correct Answer: C

Explanation:

C. The subject is “foreign objects” which is a plural noun that requires a plural verb. Eliminate Choice A, as “basis that is daily” is an awkward way of saying daily basis. Eliminate Choice D for having a singular verb, “attacks.” Eliminate Choice B, as “that attacking” is inappropriate; “that attack,” as seen in Choice C, is preferable.
