. . . . . . . . you . . . . . . . . up the form for next exam? A. Did, filled B. Will, fill C. How, fill D. When, will

The correct answer is: Will, fill.

The question is asking about the future, so the verb must be in the future tense. The only option that is in the future tense is “will fill”.

The other options are not correct because they are not in the future tense. “Did” is in the past tense, “how” is an adverb, and “when” is a conjunction.

Here is a more detailed explanation of each option:

• Did is in the past tense. It is used to talk about things that happened in the past. In this case, it would not make sense to use the past tense because the question is asking about the future.
• How is an adverb. It is used to ask about the way something is done. In this case, it would not make sense to use “how” because the question is asking about whether or not someone will do something.
• When is a conjunction. It is used to ask about the time when something will happen. In this case, it would not make sense to use “when” because the question is asking about whether or not someone will do something, not when they will do it.

Therefore, the correct answer is “will fill”.
