Ptolemy believed that Earth was at the center of the universe. Kepler believed that the sun was at the focus of Earth's elliptical orbit. Which of these statements best explains why Ptolemy and Kepler made different observations about the solar system?

The focus of their study was different.

or

They could not match the data with the observations.

The correct option is;

They could not match the data with the observations

Explanation:

Ptolemy proposed the geocentric model based on the observation that the from there are equal number of above and below the horizons at any given time, which didn't match the data observed

Kepler believed the Sun was the focus of Earth's elliptical orbit due to disparities between data in Tycho Brahe's astronomical records and the geocentric model of the solar system.

Therefore, Ptolemy and Kepler made different observations about the solar system because they could not match the data with the observations.
