This looks like homework and all you want is the answer!

joey, the rules of this board are not to give you direct answers. If you give us your answers, and why you chose those answers, we will tell you where you made mistakes, if any. But, you won't learn a single thing if we just give you the answers, and this forum is here to help you learn, not just copy answers from.

Do you understand that these are just asking for examples and definitions? Not much "thinking" is required. I'll bet if you look in your textbook, you will find all the definitions given.

Don't make it harder. Try to visualize the questions being asked. If your not sure about which answer to put in look it up in the dictionary.
