Fill in the blank with the most appropriate word. Alice _____back from America last month.

The correct answer is B. Came.

The verb “come” is used to describe the action of moving to a place. In this sentence, Alice is moving back to her home country, so the past tense form “came” is used.

The other options are incorrect because they are not the past tense form of the verb “come.”

• Option A, “come,” is the present tense form of the verb.
• Option C, “comes,” is the present tense form of the verb with a third person singular subject.
• Option D, “coming,” is the present participle form of the verb.
