Explanation / Answer

a) High birth rates were offset by high death rates due to wars, famines, and epidemics prior to 1750. True

Reason: Prior to 1750 due to poor health condition & frequent wars, famines & epidemics cause high death rates. Also birth rates were high that time due to illiteracy.

b) Women marrying later in life tend to reduce the birth rate in a population. True

Reason: Women marrying earlier will have children earlier & they will bear more children over their lifetime than women who had married later.

c) The birth and death rates, while changing over the years, have been fairly consistent across populations within a given time period, even comparing developed vs. developing countries. False

Reason: It can't be possible as developed countries will always have lower death rates due to improve health conditions & also they tend to have lower birth rate compare to developing countries due to literacy.

d) Improvements in public health decreased the overall death rates in populations. True

Reason: Improve health condition always decrease the death rates.

e) Human global population growth is beginning to level off as it has now hit the Earth’s carrying capacity. False

Reason: Carrying capacity is dependent on the number of people on the planet, but the number of consumers and the scale and nature of their consumption. Thus, carrying capacity varies with different cultures & the level of economic development. Finally, we certainly can't tell what earth's carrying capacity is.

f) As total fertility rates go down, the birth rates in all countries will decrease, regardless of the age structure of the population. False

Reason: It will take several generations to be reflected in birth rates due to the age distribution which must reach equilibrium; as already high fertility produced large number of young couples who will be in their child bearing years.

g) The total fertility rate varies between regions, and in most regions has decreased over the last 30 years. True

Reason: Due to increase literacy rate & availability of contraceptives help to lower the total fertility rate.

h) If the average fertility rate globally drops to around 2.0, the global human population size will begin decreasing. False

Reason: The statement is false.
