The two correct answers are:
1. The model accurately predicted the movements of the planets.
2. Suitable technology was not available to disprove the model.
The correct answers are:
1. Suitable technology was not available to disprove the model.
2. Observations with telescopes confirmed the predictions made using the model.
Explanation:
1. Suitable technology was not available to disprove the model: In ancient times, scientists did not have advanced technology or equipment to make accurate observations of celestial bodies and their movements. Without the ability to consistently disprove the geocentric model, it remained accepted.
2. Observations with telescopes confirmed the predictions made using the model: When telescopes were invented and used for astronomical observations, they initially supported the geocentric model. With limited resolution and understanding of the observed phenomena, the observations seemed to align with the predictions made by the geocentric model, further reinforcing its acceptance.
It is important to note that the geocentric model being "correct" or "accurate" is not one of the reasons why it was accepted by scientists for many years. The geocentric model was eventually replaced by the heliocentric model, which provided a more accurate explanation of the solar system.
