Are the combinations of population growth rate and increase in rate of
  water usage that you entered in Table  reasonable? Explain. What will be an ideal response?

Question 2

Which variable (population growth rate, rate of increase in water use, or
  precipitation) do you think has the least infl uence on water balance?
  Explain. What will be an ideal response?

Answer to Question 1

The values that students entered in the table should be very low in order to achieve a
water balance on the graph in 2050. A population growth rate of 0 percent, for example,
would be unreasonable.

Answer to Question 2

Answers will vary. By experimenting with each of the variables in the spreadsheet,
students may fi nd that the population growth rate has the most infl uence on water
availability.
