Answer to Question 1

c

Answer to Question 2

Saving and investing entails risk because individuals are bearing the burden of the possibility that investments might not pay out or that inflation might erode the value of savings. The reward for bearing risk is above-normal profits. The higher the risk, the higher the potential for above-normal profits. Income taxes reduce the return on bearing risk. On the other side, however, government does not subsidize losses from risk taking. Thus, income taxes create a bias against risk taking and innovation.
