True/False/Uncertain... Monopoly and Moral Hazard & Adverse Selection

This last question on my econ problem set is killing me... Any help?


For each of the following decide whether the statement is true, false, or uncertain and explain why. Your explanation is the important part of the answer.

a. Monopoly leads not only to production occurring at less than the level where MB = MC, but also to misallocation of the good among consumers.

b. Both moral hazard and adverse selection act to make the equilibrium quantity of health insurance less than the allocatively efficient amount.
