Test question
On the test we had to identify: The adviser keeps tabs on her students (or something like that). I said this was an idiom because you can't modify it as in: keeps many tabs on; nor can you change it as: keeps files on. To me this would make it lose its intended meaning completely. What did you all answer?

Sadly, I think I skipped that one, hoping to get back to it later and unfortunately ran out of time. I think I would probably classify it as an idiom as well.
