<p>I am confused trying to understand this one.</p>
<p>Although the senator has been involved in unethical behavior, her constituents continue to show strong support for her.</p>
<p>(A) has been involved
(B) involved
(C) being involved
(D) has yet to be involved
(E) is involving</p>
<p>I thought the answer should be B but the book says it's A. Can anyone explain why it is A? I am not clear about has, have, had, can, could, may, might, shall, and should. I will be glad if someone can clear them up. Thanks.</p>
<p>’‘has been involved’’ is totally the good answer.
"involved’’ would define the senator, but not the action itself. If there was an answer ‘‘was involved’’ then the the answer would be debatable, but right now no answer except A make sense.</p>
<p>That’s the past perfect tense. It’s always formed with have + past participle of the verb. The tense is used to emphasize that something has happened in the past.</p>
