Complete the gossipy text message with the correct question format.

I heard Sarah went on a blind date yesterday, but she won't tell me anything! Who ___?

The correct answer is did she meet.

This is an object question. You are asking about the object of the verb (the person Sarah met), while Sarah is the subject.

For object questions in the past simple, we must use the auxiliary verb did followed by the subject and the base verb: Question Word + did + subject + base verb (Who did she meet?).
