Well, when John says," Wind energy actually comes from the Sun," I note that he isn't saying 'Wind energy and Sun energy are the same thing,' so you can rule out those answers. In point of fact all statements 1-4 are correct. You just have to reason out which answer is best, based on the question.

Ah, now, Venn diagrams are only good if you know how to use them. Try looking up a how-to page on the 'Net. I can't help you without actually seeing them and talking to you.

Again, the 3rd question here is based on your own reasoning and a sort of Venn Diagram, but without the diagram. Where to place algae? Does it fit in either category by definition?

Look, homeowkr question are acceptable since this is yaho answers which is for answering any questions.

BUT, asking 50 questions in a homework mood is just lazy. Seriously, if you want to know the answer to a question, ask A QUESTION.

A homework question is alright if it is a QUESTION. Any question is acceptable if it is a QUESTION.

What you have here is some sort of homework sheet, or a section of an exam paper.

If I am wrong and you made the questions up, then you need to know how to format a powper yahoo answers question.
