  What will be an ideal response?

Question 2

A government wants to build a hydroelectric dam to reduce flooding in a region and provide electricity to its people.
 
  What type of investment is this? In order to make a decision about whether or not to make the investment, how should the government evaluate this project?

Answer to Question 1

The marginal product curve is the slope of the total product curve. Thus, marginal product is positive as long as total product is rising.

Answer to Question 2

A dam is an infrastructure or social investment. The government should estimate the expected returns from the dam over its lifetime and compare them to the expected construction costs by calculating a return on investment. If the return is greater than the opportunity cost, the government should build the dam.
