[amp_mcq option1=”were being” option2=”have been” option3=”are” option4=”No improvement” correct=”option3″]
The correct answer is “have been.”
The verb “to be” has several different forms, depending on its tense and usage. In this case, the sentence is in the present perfect tense, which is used to talk about events that started in the past and continue to the present. The present perfect tense is formed with the auxiliary verb “have” and the past participle of the main verb. In this case, the main verb is “to be,” so the past participle is “been.”
The other options are incorrect because they do not use the present perfect tense. Option A, “were being,” is in the past progressive tense, which is used to talk about events that were happening at a specific time in the past. Option B, “are,” is in the simple present tense, which is used to talk about events that happen regularly or repeatedly. Option C, “is,” is also in the simple present tense.
Therefore, the correct answer is “have been.”
