Answer to Question 1

B

Answer to Question 2

The obvious benefits of controlling flooding are offset by loss of sediment deposition area, loss of wetland habitat, loss of the natural evolution of a drainage basin (natural changes in the stream channel such as meandering), increased soil erosion, and decreased natural ability to moderate effects of floods.
