Confusing – Main Idea - Short Texts: Review

We are using during summer to strengthen writing skills. But I totally disagree with a lot of these answers. There will be one sentence shown. The answers that show as correct are not included in the sentence. They are included in the longer passage at the top. This happens often and I consider your answers incorrect. How can I use this as a learning tool when I disagree?
