Hi,
I saw a test recently for Past Simple/Past Progressive which had the question:
When I (walk) _______ into the office, the secretary (talk) ___________ on the phone.
As a native speaker, I think that there are 4 possible answers to this question. Any of them would be correct, depending on the context of the "story" (there wasn't one in the test, this was a 'stand alone' question).
What would you do? Would you give the points whatever the student wrote?
Obviously, the correct way would be not to have it in the test in the first place!
Thanks
