It seems as if you are just randomly selecting answers to get us to respond. I only checked the answers where SraJMcGin did not give an information source. With 4 alternatives, you can get 25% of the answers right by pure chance. From what I checked, that is about as good as you are doing. Try looking up the terms for the alternatives in the subject index of your textbook before posting your questions.
