Multiple Choice

Which sentence best explains the difference in position between the curve for r = 1.00 and the curve for r = 0.25?

A) The r = 1.00 curve adds a larger multiple of the population size at each time interval than does the r = 0.25 curve.
B) The r = 1.00 curve adds a smaller multiple of the population size at each time interval than does the r = 0.25 curve.
C) The r = 1.00 curve adds a multiple of the population size at each time interval and the r = 0.25 curve adds the same number each time.
D) The r = 1.00 curve adds the same number to the population size at each time interval; the r = 0.25 curve adds the same number, but a smaller number, each time.
E) The r = 1.00 curve adds the same number to the population size at each time interval; the r = 0.25 curve adds the same number, but a larger number, each time.
