Question

Fill in the blank with the most appropriate word.
Maria ________ at home yesterday.

• A. is
• B. were
• C. was
• D. went

Answer 1

Answer: (C)

Here, 'was' in Simple Past Tense is correct because it indicates an action that has already been completed. Here, Maria 'was' at home yesterday (action already completed).
'Is' in present continuous is incorrect because it implies an action going on at the time of speaking.
'Were' is incorrect because the subject is singular, and not plural. So, 'was' is correct.
