Question

all but one of the factors listed is a major contributor to world population increases. that factor is

a. increased birth rate.

b. decreased death rate.

c. increased immigration to foreign countries.

d. an increase in the quality of medical care.

Explanation:

To determine the factor not contributing to world population increase:

• Option A: Increased birth rate directly adds to population.
• Option B: Decreased death rate means more people survive, increasing population.
• Option C: Immigration to foreign countries involves movement of people (redistribution), not a net increase in world population (as people move between countries, not create new individuals).
• Option D: Better medical care reduces death rate (similar to B), increasing population.

Thus, immigration to foreign countries does not increase the global population.

Answer:

C. increased immigration to foreign countries.
