Question

what change, if any, should be made in sentence 6?
(6) students released the butterflies and watched as it fluttered away into the bright blue sky.
change \as it fluttered\ to \them flutter\
change \butterflies\ to \them\
no change needed
change \students\ to \we\

Explanation:

The subject "butterflies" is plural, so the pronoun referring to it should also be plural. In the original sentence, "it" (singular) is used to refer to "butterflies" (plural), which is incorrect. Changing "as it fluttered" to "them flutter" corrects the pronoun - antecedent agreement, as "them" is the appropriate plural pronoun to refer to "butterflies" and the structure "watch them flutter" is grammatically correct. Changing "butterflies" to "them" would make the sentence unclear as "them" would be without a clear antecedent in that context. There is a grammatical error in the original sentence, so "No change needed" is wrong. Changing "students" to "we" is unnecessary and does not fix the grammatical error.

Answer:

A. Change "as it fluttered" to "them flutter"
