Question 2

Galileo supported the heliocentric model (sun - centered), while many people at that time believed in the geocentric model (Earth - centered, where sun and planets revolve around Earth). The other options are incorrect: advanced math understanding, telescope fire, and secretive research methods are not reasons for opposing his theories.

The four Galilean moons of Jupiter (named after Galileo) are Callisto, Io, Ganymede, and Europa. Deimos, Phobos are moons of Mars; Titan is a moon of Saturn; Aoede is not a Galilean moon.

Answer:

A. They believed that the sun and other planets revolved around Earth.
