Explanation:
In the early 1950s, American leaders repeatedly told the public that they should be fearful of subversive Communist influence in their lives. Communists could be lurking anywhere, using their positions as school teachers, college professors, labor organizers, artists, or journalists to aid the program of world Communist domination. This paranoia about the internal Communist threat—what we call the Red Scare—reached a fever pitch between 1950 and 1954, when Senator Joe McCarthy of Wisconsin, a right-wing Republican, launched a series of highly publicized probes into alleged Communist penetration of the State Department, the White House, the Treasury, and even the US Army. During Eisenhower’s first two years in office, McCarthy’s shrieking denunciations and fear-mongering created a climate of fear and suspicion across the country. No one dared tangle with McCarthy for fear of being labeled disloyal.
"Any man who has been named by a either a senator or a committee or a congressman as dangerous to the welfare of this nation, his name should be submitted to the various intelligence units, and they should conduct a complete check upon him. It’s not too much to ask."
Senator Joseph McCarthy, 1953
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.
