Question

q9. (s c.6.n.2.2)
the geocentric theory once placed earth at the center of the universe, but it was replaced by the heliocentric theory. what best explains this change?
scientists voted to switch theories every 100 years.
scientists preferred a new idea without proof.
new evidence from telescopes supported the sun - centered model.
scientific laws forced the change.

Explanation:

Scientific theories change based on new evidence. Telescopes provided observational data that supported the heliocentric (Sun - centered) model over the geocentric one. Scientists don't change theories by voting or preferring unproven ideas, and scientific laws are different from theories and didn't force this change.

Answer:

New evidence from telescopes supported the Sun - centered model.
