23) Choose the best answer: Do humans have an effect on the frequency of natural disasters?

A) No. Natural disasters are caused by forces internal to the Earth.

B) No. Natural disasters are random and people cannot affect them.

C) Maybe. Some natural disasters are random, but some are caused by humans.

D) Yes. Land use by humans can increase the frequency or size of natural disasters such as flooding or landslides.
