PASSIVE VOICE

The passive voice removes the subject from the sentence. It is formed with the verb to be and the past participle of the main verb.

Passive: The bill was resubmitted.

Active: The Senator has resubmitted the bill.

Unless you want to de-emphasize the doer of an action, you should favor the active voice.

Example:

In the past few years and to this day, many teachers of math and science had chosen to return to the private sector.

(A) had chosen to return to the private sector.
(B) having chosen to return to the private sector.
(C) chose to return to the private sector.
(D) have chosen to return to the private sector.
(E) have chosen returning to the private sector.

Choice (A) is incorrect because it uses the past perfect had chosen, which describes an event that has been completed before another event. But the sentence implies that teachers have and are continuing to return to the private sector. Hence, the present perfect tense should be used.

Choice (B) is incorrect because it uses the present progressive tense having chosen, which describes an ongoing event. Although this is the case, it does not capture the fact that the event began in the past.

Choice (C) is incorrect because it uses the simple past chose, which describes a past event. But again, the sentence implies that the teachers are continuing to opt for the private sector.

Choice (D) is the correct answer because it uses the present perfect have chosen to describe an event that occurred in the past and is continuing into the present.

Choice (E) is incorrect because it leaves the thought in the sentence uncompleted.
