Hello! I am having trouble with all of these questions. I have spent about 8 hours on them, and I have given up. If someone could just give me the answers, I would appreciate it a lot. Once I have the answers, it makes it easier for me to understand why the answer is so. Thank you so much for the help!

can you make your questions more clear as I was unable to read them, it seems the questions are scanned images, I tried even to zoom it to get clear image. If I am able to read the question properly, I will try my best to answer, of course one question at a time.
