Read the sentence.

Many people visit the Washington Monument each year.

Identify the principal part used to form the underlined verb in the sentence.

A. present participle

B. past

C. past participle

D. present

The correct answer is D. present.

The verb visit is used in present simple tense, but to shorten it, you can just say present tense. Present participle would be visiting (just add - ing to create present progressive tense), past would be visited (past simple tense), and past participle would be (have/had) visited - used in present/past perfect tense.

The answer is past. I hope you have a nice day!
