Board . . . . . not . . . . . . this question in the previous exam. A. did , ask B. was , ask C. does , ask D. will , ask

The correct answer is: A. did, ask.

The board did not ask this question in the previous exam. This is because the question is about a past event, and the verb “ask” takes the simple past tense to describe past events. The other options are incorrect because they use verbs that do not agree with the tense of the sentence. The verb “was” is in the past tense, but it is used to describe a state of being, not an action. The verb “does” is in the present tense, but it is used to describe habitual actions, not one-time events. The verb “will” is in the future tense, but it is used to describe future events, not past events.

Here is a more detailed explanation of each option:

• Option A: did, ask. This is the correct answer because it uses the simple past tense to describe a past event. The board did not ask this question in the previous exam.
• Option B: was, ask. This is incorrect because it uses the past tense to describe a state of being. The board was not asking a question, it was not in a state of asking a question.
• Option C: does, ask. This is incorrect because it uses the present tense to describe a habitual action. The board does not ask this question every exam, it asked this question once, in the previous exam.
• Option D: will, ask. This is incorrect because it uses the future tense to describe a future event. The board will not ask this question in the next exam, it asked this question in the previous exam.
