Question

10 based on source 1, which of the following best explains how human factors affect population distribution? a in highly developed countries like sudan, many people choose to emigrate when pollution and overcrowding become an issue to their health. b civil wars in africa have forced a significant number of people to migrate from one region to another and in postcolonial africa. c the vast majority of migrants moved to wealthy cities in nearby countries to work in the technology industry. d the lack of government oversight resulted in a nuclear meltdown in a major city, causing most residents to flee to other countries.

Explanation:

• Option A: Sudan is not a highly developed country, so this is incorrect.
• Option B: Civil wars are a human - made factor (conflict) that can force people to migrate, which is a valid way human factors affect population distribution.
• Option C: There is no indication that the majority of migrants in the context of the question move to work in the technology industry, and this is not a typical or well - supported way human factors affect population distribution in the general sense related to the question.
• Option D: A nuclear meltdown due to lack of government oversight is a more specific and less common event compared to civil wars as a factor affecting population distribution, and civil wars are a more direct human - related factor for population movement in Africa.

Answer:

B. Civil wars in Africa have forced a significant number of people to migrate from one region to another and in postcolonial Africa.
