Question

_____ you know where John lives?

• A. Do
• B. Does
• C. Was
• D. Has

Answer 1

Answer:

A. Do

Primary auxiliary verbs which are derived from the verb DO are do, does and did. In the simple present tense, do will function as an auxiliary to express the negative and to ask questions. Does, however, is substituted for third-person, singular subjects in the present tense. The past tense did works with all persons, singular and plural. Eg : Do you attend this school?
