Which process can decrease the population of an area?

Answer and explanation

Correct answer: Deaths and out-migration

Direct answer: Option B is correct. Deaths reduce the number of people living in an area, and out-migration occurs when residents leave that area for another place. Therefore, both processes can decrease the population of the original area. Option A is wrong because births add people and in-migration brings people into the area. Option C is wrong because births generally increase population, while education is not itself a direct process that removes people. Option D is wrong because in-migration adds people; healthcare services may affect living conditions but are not a direct population-decreasing process. To solve such questions, classify each process as an addition or a reduction. Memory cue: deaths and departures take people out; births and arrivals bring people in.
