Answer:
a) Skepticism allowed Galileo to question what he had already learned about objects in the solar system.
Step-by-step explanation:
What is skepticism? Is the action of doubt about a predefined idea after careful consideration. When Galileo looked at the sky, the sky he knew was based on the theological perception inherited from the Greek astronomer Claudius Ptolemy, and his theory of geocentrism and the idea of a Universe that never change. From the moment Galileo targets his telescope toward the stars, he saw things that were different from what was established. He begins to doubt, and the skepticism aids him to question the Ptolemy astronomy, beginning a fight with Church.
