Question

1. which sentence uses the verb in the present perfect tense? the students write persuasive essays each quarter. the teacher wrote detailed comments on every draft. the journalist is writing an opinion piece. the editors have revised the article several times. 2. which sentence is written in passive voice? all the applications were reviewed by the manager. the manager will review applications tomorrow. the manager is reviewing applications now. the manager reviewed all the applications.

Explanation:

1. The present - perfect tense is formed by "have/has + past participle". In "The editors have revised the article several times", "have revised" follows this structure. The other sentences are in simple present ("The students write..."), simple past ("The teacher wrote..."), and present continuous ("The journalist is writing...").
2. A passive - voice sentence has the object of the action as the subject and uses a form of "be" + past participle along with "by" to show the doer of the action. "All the applications were reviewed by the manager" is in passive voice as it has "were reviewed by". The other sentences are in future simple ("The manager will review..."), present continuous ("The manager is reviewing..."), and simple past ("The manager reviewed...") in active voice.

Answer:

1. The editors have revised the article several times.
2. All the applications were reviewed by the manager.
