Which statement describes the phenomena studied with telescopes according to the passage?

• A. Plate tectonics
• B. The speed of light and gravity
• C. The speed of the sound
• D. Magnetic fields

Answer: (B)

Telescopes are instruments that collect and analyze light from distant objects, allowing us to study how light behaves in space and how gravity affects it, such as bending or shifting light as it passes near massive objects. That makes the statement about the speed of light and gravity the best fit, because it directly connects what telescopes reveal about light and gravitational effects in the universe. Plate tectonics concerns Earth’s crust movements, the speed of sound relates to acoustic waves in mediums like air or solids, and magnetic fields are about magnetic forces—topics not what telescopes primarily investigate.
