Answer:
The population of country A will increase faster than that of country B.
Step-by-step explanation:
The fertility rates of both countries have been identified to be 3.5. However, if women in country A have children two years earlier than women in country B and suppose there is no birth control in such country, the population of both countries will increase. However, because country A women gives birth 2 years before country B, the population of country A is bound to increase faster than that of country B.
