Question

Fill in the blank with the most appropriate option.
They will leave the house as soon as they ____ lunch.

• A. finish eating
• B. will finish to eat
• C. finish to eat
• D. will finish eating

Answer 1

Answer: (A)

finish eating

The sentence indicates that the subjects are doing an activity currently and that the subjects will leave as soon as that activity is complete. Thus, the activity (the answer) must be ongoing and since it is what the subjects are currently doing, it must be in the present tense. Thus, the answer must be in the present continuous tense.

Option A is correct. 'finish eating' is in the present continuous tense. Thus, it has the required tense and is the correct answer.

Option B is incorrect. 'will finish to eat' is in the future tense and also, it does not indicate that the action is ongoing. Thus, it is not the correct answer.

Option C is incorrect. 'finish to eat' is in present tense and not present continuous tense. Thus, it does not indicate that the action is ongoing. Thus, it is incorrect.

Option D is incorrect. 'will finish eating' indicates that the action is ongoing but, it is in the future tense and not the present tense. Thus, using it will make the tense of the sentence inconsistent.
