> Please explain your answers
Please explain your lack of an attempt at the solution, or your disregard of the forum posting guidelines.
We're not here to give you answers on a plate so you can get a decent grade you don't deserve.

You have a guess (or better yet, think about it and refer to some notes) and explain your reasoning, then we tell you where the faults in your reasoning might be.

The real answer to Q1 isn't even on your list.
