1. I have changed your thread title. "Choose" is useless as a title. Titles must include some/all of the words/phrases/sentences you're asking us to look at.
2. Where did you find this terrible exercise? It makes no sense at all.
3. When you write a post here, you need to give us more information - the source, why you're asking us about it, what you're asking us to do. You can't just post something like this and expect us to read your mind.
