Question

Select the word or group of words you consider most appropriate for the blank space.
Years __________ since I was here last.

• A. have passed
• B. had passed
• C. had been passing
• D. have been passing

Answer 1

Answer: (A)

have passed

When the main verb in a sentence with a since clause (since I was here) refers to a period of time including the present, a present perfect tense is necessary. Hence, option A, 'have passed' is the correct answer.

Options B, C and D are incorrect because they are in the past perfect, past perfect continuous and present perfect continuous tense respectively.
