Correct answers:
- They supported the heliocentric model.
- They established the laws of planetary motion.

Brief explanation: Kepler showed planets move in ellipses (not perfect circles), quantified their speeds (area law), and related orbital period to distance (harmonic law), which strengthened Copernicus’s heliocentric system. He did not explain sunrise/sunset (that’s Earth’s rotation) nor specifically make astronomy accessible to Italian speakers.
