I think the answer is letter b. The Nigerian government purposely targeted Biafran boys..
Based from the story, many people died during the civil war.
Jonathan’s son was one of the civilians who have died. The Nigerian Civil War
was a war between Biafra and Nigeria when Biafra had fought for their
secession.
The post World War 2 baby boom was caused by A) marriage at an earlier age.
Let's look into te options one by one:
A) marriage at an earlier age.
This is true.
As there was a lack of sense and knowledge of birth control in the developing countrues due to insufficient education, people usually get marry at an early age as well as giving birth at a early age, and this cycle continues to cause the birth rate to be high.
B)the loss of population during the war
This is false.
The loss of population indeed happened however the effect of this should be decreasing the birth rate due to lower population density. The will to give birth is also not due to there is lack of population.
C) women refusing to go back to work after war
This is false.
Contrarily, more women started to work after WWII as much menpower is used on the war as army. Many continues to take up the role of labour after WWII to make a living.
D) the invention and distribution of the birth control pill
This is false.
The insvention of it would be used to control the birth rate instead of causing an increase and thus is incorrect.
Therefore the answer is A) marriage at an earlier age.
Hope it helps!
