D.

Answer 1

The answer is C. Galileo made important improvements to both instruments.

Some people believe that Galileo was the first person to build a telescope.

This is not true, but he was the first person to publish his observations of astronomical objects through a telescope. He discovered that the Milky Way is made of many stars. He discovered that the Moon has hills.

He found four moons around Jupiter.

Those moons are now called the Galilean moons. He discovered sunspots, which are dark areas of the Sun. He saw that the planet Venus has light and dark phases just like the Moon. This helped people to know that the Sun is at the centre of the Solar System, as Nicholas Copernicus had said.
