A. improved social and medical facilities
B. stable government
C. rainfall and its reliability
D. agricultural system practiced
Correct Answer:
Option A – improved social and medical facilities
Explanation
The provision of modern and improved medical and social facilities to area tends to attract more population concentration to another.
Other options are wrong because the government being stable does not determine population growth, social amenities provided by the government is the only factor that can make the population growth low, either rainfall or not, people will migrate and reproduce.
The agricultural system practical in an area also does not determine rapid population growth. Either mono-cropping or mixed farming is practiced population will always grow.
