Question

pick the words that correctly complete the sentence. they have _____ in colorado for the last two years. been living are living be living were living

Answer 1

Answer: The words that correctly complete the sentence are "been living": "They have been living in Colorado for the last two years".

Explanation: The Present Perfect Progressive Tense can only be formed with the modal verb "have" + "been" + the present participle of a verb, that is a verb ending in "-ing". In that way, the words that correctly complete the sentence are "been living" since "are", "be" and "were" cannot come after the modal "have" to form the Present Perfect Progressive Tense, which is mainly used to refer to a situation that started in the past and that is still in progress at present.

Answer 2

Been living in because the rest of them don't make sense if you were to put them in the sentence.
