Answer to Question 1

D

Answer to Question 2

Assume you have a valuation of the good equal to 50. The price the winning bidder pays is equal to the second highest bid. If you bid 70 and win you will pay less than 50 if the second-highest bid (SHB) is less or equal to 50. In this case you are as well off as bidding 50. If you end up paying more you lose because you are paying more than your valuation of the good. So you are either as well off or worse off than bidding your highest valuation.
