#1: the correct answer is “nothing” – are you sure you chose that? In a properly grounded circuit, neutral will have ground potential. So, there is no potential difference between the neutral wire and ground, so no current would flow through you.
#2: Same reason as #1 – neutral and ground (in a properly grounded circuit) will have no voltage difference between them. Remember that voltage readings are always a comparison between two points. If you measure L1 to neutral, you should get 120v.
