Answer to Question 1

B

Answer to Question 2

MPL = = = . This ratio will decline when L rises. MPK = = = . This ratio increases with L. Adding more labor input causes the capital input to be spread more thinly (each unit of labor has less capital to work with), so output increases at a diminishing rate. More labor input means, also, that the available capital is being used more intensively (each unit of capital has more labor to work it), so the change in output that would result from a change in the quantity of capital is becoming larger.
