Choose the right variant. Did you _______ your friends last Friday?

The correct answer is 'met'.

Explanation:

The sentence 'Did you _______ your friends last Friday?' is a question in the past simple tense. The auxiliary verb 'did' is used to form questions in the past simple. Therefore, the main verb should be in its base form, which is 'meet'. However, since the action happened last Friday, we need to use the past form of the verb 'meet', which is 'met'.

So, the correct sentence is: 'Did you meet your friends last Friday?'
