Question

Complete the phrase

P.S.: Could you please explain your answer to me? Why didn't you choose another alternative? Please explain it to me using grammatical rules.

He________his atitude towards his colleagues since he________.


A) changed / was promoted

B) Is changing / has been promoted

C) Has changed / has been promoted

D) Has changed / was promoted

Answer 1

The answer is D. You have to keep the verb tenses the same as well as active/passive voice. For 'A', you have active voice/passive voice. For 'B' and 'C', the verb tenses are not the same (b is present tense/past tense and c is past tense and past perfect tense). 'D' can be the only correct answer in following grammar rules.
