Human beings perspire

Question and options

Human beings perspire
  1. to keep good health
  2. because of high blood pressure
  3. because of tension
  4. to cool the body

Answer and explanation

Correct answer: D - to cool the body
Sweating is the body's way of regulating its temperature: as sweat evaporates from the skin it carries heat away, which cools the body, especially in a hot environment or during exercise. High blood pressure and tension are not the reason humans perspire, and general good health is not its function.
