Which statement is supported by the text about telescopes and astronomy?

• A. The Use Of Telescopes Led To Important Discoveries
• B. Telescopes Studied Gravity And The Speed Of Light
• C. Galileo Discovered Moons Orbiting Jupiter
• D. The Telescope Study Had No Impact On Astronomy

Answer: (A)

Telescopes extend our view of the cosmos, letting us observe things far beyond what we can see with the naked eye and gather data that would be impossible otherwise. Because of this, their use has led to important discoveries in astronomy, transforming our understanding of planets, stars, and galaxies. This makes the statement that the use of telescopes led to important discoveries the best-supported one. The other ideas either misstate what telescopes do or overstate a single detail: gravity and the speed of light are topics of study in physics, not the primary purpose of a telescope as an observational tool; mentioning a specific discovery by Galileo points to a historical example but doesn’t capture the general impact of using telescopes; and claiming there was no impact contradicts the well-documented advances enabled by telescope observations.
