Question

im writing a paper comparing and contrasting the government , art, and religion of ancient Greece, Rome, and the Middle ages, and i don't know how to make an outline....?

Answer 1

You are comparing two governments with an era? That might be difficult.

first, figure out what you are to do: I suspect something is wrong with Greece, Rome, and the Middle Ages.
Second, figure out what you want to say.

A draft outline will follow.

Answer 2

Study these sites about outlining.
