Write one word in each gap.

To be honest, biology is definitely my cup of [ ]. I enjoy learning about how nature works. All the tests and exams are a piece [ ] cake for me. But I've been having some troubles with biology recently. I didn't do my homework (just once!), and my friend Judy spilled [ ] beans and told the teacher about it.

The teacher took her words with a pinch of [ ] and decided to check my notebook himself. There was no homework in it! So, I got a D and now I need to take extra classes to improve the mark.

I understand there's no point in crying over spilt [ ], but I'm so angry with Judy!!!
