Read the passage: "The Geocentric Model" in the box below.

THE GEOCENTRIC MODEL
Ancient scientists believed in the geocentric model, which stated that Earth was the center of the solar system, as evidenced by the motion of celestial bodies throughout the sky each day. However, as knowledge and technology improved, other ideas began to emerge. With the advent of the telescope, the path of the solar system’s bodies could be more accurately determined. New evidence began to emerge, and eventually a new theory, the heliocentric, or Sun-centered, solar system, was developed.
Why did the knowledge about Earth’s position in the solar system change?

A. Because scientists could not find enough evidence to support their original solar system theories.
B. Because celestial bodies changed their positions in space and eventually Earth orbited the Sun.
C. Because new technology gave scientists new evidence that changed their interpretation of celestial movement.
D. Because new technology made it easier for scientists to think of more plausible stories to describe natural events.
