What is the main idea in this passage?

Galileo Galilei was an influential scientist and one of the early developers of the refracting telescope. In 1632 Galileo published a book called Dialogue Concerning the Two Chief World Systems, in which he compared the Copernican view of a heliocentric universe, one where the sun is at the center, with the geocentric view, one in which the Earth is at the center. The Church took offense as to how Galileo portrayed the geocentric view using a character named Simplicio, which has undertones of simpleton in the Italian language, and he was put on trial before the Roman Inquisition. The Inquisition ordered Galileo to recant his ideas, his book was banned, he was forbidden from publishing anything else, and he was sentenced to house arrest for the rest of his life. I guess it's not just what you say that's important but how you say it. (5 Points)

1) The sun is at the center of the universe

2) Galileo was punished severely for publishing his book

3) The earth is at the center of the universe​
