Question

Where did
she go and what did she do?​

Answer 1

Answer:

Question no.1 refers to a particular time in the past, the speaker does not know where the person was. In theory, "was" could refer to any time in the past, but context will tell us if the speaker is talking about ten minutes or ten years ago.

Question no.2 refers to the present, i.e., "now". The speaker does not know the whereabouts of a person at the time of speaking. "She" is not here.
