I'm assuming that the blank means you can put anything in it without using the words from the sentences and that you can switch up the words in the sentences to make questions without it being in that order.
1. Will I pick you up from the train station?
2. Not sure on this one cuz I don't know how you could put "I'm" in a question.
3. Is she dancing to the disco?
4. Do you need to drive to the 3rd floor?
5. Did we get enough food in the health food store?
6. Didn't we meet a lot of people there?
7. Did you see her on the ground floor?
8. Are we going to the department store?
I think I did this right? I hope it helps.
