3,000 years ago the ______ chewed coca leaves to get their hearts racing and to speed their breathing to counter the effects of living in thin mountain air.

Explanation:

Question 19

Cocaine tolerance is known to develop quickly as the body adapts to the drug's effects rapidly with repeated use. "Never" is incorrect as tolerance can develop. "After the first time" is not accurate as tolerance typically builds with more use but the rate is quick. "Over time" is too vague and doesn't capture the rapid development.

3,000 years ago, the Incas (or Andean peoples) chewed coca leaves to counter thin mountain air effects. The most common answer here is "Incas" (or sometimes "Andean people").

Answer:

A. quickly
