a tradition and reliance on church teachings.

b observation and experimentation

c classical learning and travel

d divine wisdom and biblical texts

Explanation:

First Question (Which earlier work made Galileo’s discovery so significant?)

Galileo's astronomical discoveries supported the heliocentric theory. Copernicus proposed the heliocentric theory (sun - centered solar system) before Galileo. Magellan's circumnavigation was about geography/exploration, Priestly's oxygen isolation was chemistry - related, and Aristotle's motion research was about physics but not related to Galileo's astronomical significance. So the correct option is b.

The Scientific Revolution emphasized empirical methods. Observation and experimentation were key as scientists started to test ideas through direct observation and experiments rather than relying on tradition, Church teachings, classical learning/travel, or biblical texts. So the correct option is b.

Answer:

b. the heliocentric theory proposed by Copernicus
