Final answer:
Africa experiences the fastest population growth due to lower economic development and limited access to family planning, while Europe sees the slowest growth due to higher economic development, an aging population, and greater access to contraception.
Step-by-step explanation:
According to recent data on population growth, the correct answer to which parts of the world experience the fastest and slowest population growth is B) Fastest - Africa; Slowest - Europe. This trend can largely be attributed to different levels of economic development and access to family planning resources. The highest growth rates are found in less economically developed countries in Africa, where there is limited access to contraception and lower levels of female education, leading to higher fertility rates. Europe, on the other hand, has a stable or declining population due to various factors, including higher economic development, greater access to family planning, and different social priorities concerning family size.
