For #1 I like (c). If you are going to tick (d) too then why not (e) as well?
Can you post your reasoning?
I didn't choose (e) because it's a voluntary response, so it wouldnt be random!
also, what about 3, 4, and 5. For 3 I just guessed because I didn't know to do - It looked like more of a conceptual problem than a plug and chug one
