Three balls are used to model the Sun-Earth-Moon system. Which statement describes a benefit of this model?

Options are not given in the question, so the complete question is as follows:

Three balls are used to model the Sun-Earth-Moon system. Which statement

describes the benefit of this model?

A. The model shows only how eclipses happen.

B. It shows information about a system too large to be studied easily.

C. It shows information about a system too fast to be studied  directly

D. The model can be used for the entire solar system.

B. It shows information about a system too large to be studied easily.

Explanation:

The use of balls in the model makes it easy to understand the large solar system.

The solar system is comprised of the sun, moon, planets, and other celestial bodies. The model using three balls makes it easy to understand a large system. Using these balls many things about the solar system can be learned such as the position of the Sun-Earth-Moon, the phenomenon of rotation and revolution, and eclipses.

So, the given models show that a large solar system can be studied easily.

Hence, the correct option is "B".
