Question

Which of the following demographic changes is NOT the likely result of a natural disaster?

Answer 1

I think the answer is A significant reduction in the population of the young occurs because they are more vulnerable to infectious diseases spread by unsanitary conditions.

In my opinion, unsanitary conditions are often man-made. For example, if a person does not clean his surroundings, this would cause bacterias from infecting the place. Then it affects the person living in that area, then spreads because through oral or sexual contacts.
