Read the sentences. Akira sewed one button back on his jacket. Then, another one falls off when he put it on to go outside. Which correction of the underlined verb fixes the inappropriate shift in tense in the second sentence?

Your question is incomplete because it does not provide the options or the underlined verb. The complete question is the following:

Akira sewed one button back on his jacket. Then, another one falls off when he put it on to go outside.

will fall

has fallen

fell

had fallen

Answer:

fell

Explanation:

The sentences describe a series of events that occurred one after the other in the past, so the correct tense is Past Simple. Actually, the second sentence begins with the word then, which indicates a sequence of actions that happened after Akira sewed the button. Thus, one of the uses of Past Simple is to illustrate an arrangement of complete actions that happen in chronological order in the past.

The rest of the choices are incorrect because will fall refers to the future, has fallen connects past and present, and had fallen specifies an action that occurred before another past action.

Answer:C fell
