Correct Answer:
C. sings well
This question assesses your understanding of subject-verb agreement and the correct use of adverbs to modify verbs. In English, verbs must agree with their subjects in number, and adverbs are used to describe how an action is performed.
- Correct Answer (C: sings well): “She” is a third-person singular subject, so the verb in the simple present tense must end in “-s” (sings). “Well” is an adverb that correctly modifies the verb “sings,” describing the manner in which she performs the action. Adverbs answer questions like “how,” “when,” “where,” or “to what extent.”
- Incorrect Distractors:
- (A: sings wells): While “sings” is correct for the subject “she,” “wells” is either a plural noun or a verb form, not an adverb. It cannot modify the verb “sings” in this context.
- (B: sing good): “Sing” is incorrect because the verb for a third-person singular subject (“she”) in the simple present tense should be “sings.” Additionally, “good” is an adjective, not an adverb. Adjectives modify nouns, while adverbs like “well” modify verbs.
- (D: None of these): This is incorrect because option C is grammatically sound.
