Question

Complete the sentence: It was so dark, we … see nothing: could can might must may

Answer 1

It was dark, we could see nothing.

Answer 2

It was so dark, we couldn't see anything. In this sentence, the appropriate word to use is "couldn't." "Couldn't" is the contracted form of "could not" and indicates the lack of ability or possibility to see anything in the darkness. The word "could" is the past tense form of "can" and expresses the ability or possibility, but in this case, it is negated by "not" to indicate the inability to see. The words "might," "must," and "may" are modal verbs that express probability, necessity, or permission, but they do not accurately convey the meaning of "inability to see" in this context. Therefore, "couldn't" is the correct word to complete the sentence.
