Here's a question: Bob and Boris were standing in a queue at the grocery store.  They were standing in place.  The line was fast, but the children in front of them were loud.   They were what?

Here are possible answers to this question:
- frustration
- being annoyed
- delays
- irritation
- out of order

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


loud children are obnoxious.
