Questions: Kevin used a kit to put together this model of the solar system. What are two limitations of Kevin's model? A. The real planets move around the Sun, but the model planets cannot. B. The distance between the planets car't be set to scale in the model. C. The model Sun can't give off heat and light as hot and bright as those from the real Sun. D. The model can't have the correct number of planets.

Solution Steps

The question asks for two limitations of Kevin's model of the solar system.

The options provided are:

• A. The real planets move around the Sun, but the model planets cannot.
• B. The distance between the planets can't be set to scale in the model.
• C. The model Sun can't give off heat and light as hot and bright as those from the real Sun.
• D. The model can’t have the correct number of planets.

• Option A: This is a valid limitation because the model planets are typically fixed and do not move like real planets.
• Option B: This is also a valid limitation because it is difficult to accurately represent the vast distances between planets in a small model.
• Option C: This is a valid limitation as well, but it is less relevant to the structural representation of the solar system.
• Option D: This is not necessarily a limitation if the model includes all the planets.

The most relevant limitations are:

• A. The real planets move around the Sun, but the model planets cannot.
• B. The distance between the planets can't be set to scale in the model.
