the spread and treatment of disease

Explanation:

A biologist is someone that studies living organisms. There are different branches of biology and a biologist can choose to specialize in one or more. These branches include but not limited to epidemiology, medicine, genetics, etc.

Epidemiology has to do with the study of diseases while their treatment and management has everything to do with medicine.

The speed of car on icy road has to do with mechanics.

Mineral content of soil has to do with geology.

The atmosphere of distant plant has to do with planetary science.

The correct answer is the spread and treatment of disease.

The spread and treatment of disease is what I believe to be the correct answer.
