The population growth rate a) increases if the death rate is not too high. b) decreases if the birth rate is not too high. c) measures the change in a population's size over time. d) tells whether or not a nation should stop allowing immigrants to move in.

D- tells whether or not sure nation should stop allowing immigrants to move in.
When small number of people die, the population growth rate increases
When small number of babies are given birth to, the population growth rate can decrease.
But when a large number of babies are given birth to, population growth rate increases

I  cant see the question.
