The scopes trial was about:
a. freedom of the press
b. teaching evolution in school
c. prayer in school

In the Scopes "Monkey trial" in 1925, a substitute school teacher was accused
by the state of Tennessee of violating the state law that made it illegal to teach
human evolution in any state funded school.

Scopes wasn't even sure whether he had ever actually taught evolution, but he
said that he did, so that the case could come to trial and be heard.
