You raid the supplies.

What supplies are they? Food? Water? Apple flavored sand?

There's 4 rooms. They probably have stuff inside, you think.

Which room do you want to go in first?

This is a meaningless question to us. The way you're asking, I imagine that you have contents for each door, but we may as well be flipping a coin; we have no context that makes the decision mean anything.
Maybe if we could see stuff on the doors? Or through the doors? Or there are signs perhaps?

We have four people and four doors. Everyone takes a different one.
