Here's a question: The faucet on the wall sprayed water high into the air.  It caught the light from the window and made a rainbow.  It was very annoying and gross to people who came into this what?

Here are possible answers to this question:
- restroom
- rainstorm
- water fountain
- sink
- directing flow of water

I believe the correct choice is "restroom", here's why:


a toilet in a public building.
