Can anyone offer an explanation as to how I would go about doing these TWO questions?
Really not sure.

Do you know the meanings of the words used here? For the second problem, If you know what an "Euler circuit" is, then you can just trace each of the given options to see which are Euler circuits.
For the first problem, in option a, having traversed edge $e_5$ you cannot then immediately go to $e_6$. For option b, can you trace a path through those vertices in order? If so, noting that you start and end at $v_2$, what kind of path is that?
