Fill in the blank with the most appropriate word. Mary _____ to the bank on Monday.

The correct answer is D. went.

The verb “go” is in the simple past tense. The simple past tense is used to talk about events that happened at a specific time in the past. In this case, the event is Mary going to the bank on Monday.

The other options are not correct because they are not in the simple past tense.

• The verb “go” in the present tense is “goes.”
• The verb “go” in the present progressive tense is “going.”
• The verb “go” in the past participle is “gone.”

I hope this helps!
