Fill in the blank with the most appropriate option. Where ________ yesterday?

The correct answer is: D. were you

The verb “to be” is used to describe the state of being or existence. It can be used in the present, past, or future tense. In the past tense, the verb “to be” is conjugated as follows:

• I was
• You were
• He/She/It was
• We were
• You were
• They were

In the sentence “Where were you yesterday?”, the verb “to be” is used in the past tense to ask about someone’s location at a specific time in the past. The answer to this question would be a place or location.

The other options are incorrect because they do not use the verb “to be” in the past tense.

• Option A: “was you” is not a grammatically correct sentence. The verb “to be” should be conjugated as “were”.
• Option B: “have you been” is used to ask about someone’s past experiences. In the sentence “Where have you been?”, the speaker is asking about the listener’s whereabouts over a period of time.
• Option C: “did you” is used to ask about someone’s actions in the past. In the sentence “What did you do yesterday?”, the speaker is asking about the listener’s activities on a specific day.
