Question

A.
George cannot move the planets around the Sun.
B.
George cannot place the planets in the correct order from the Sun.
C.
The model cannot show that the planets differ in color.
D.
The model cannot show that the planets differ in size.

Answer 1

The limitation of George's crayon model of the solar system is:

D. The model cannot show that the planets differ in size.

While other options may present challenges (like moving the planets around or placing them in the correct order), the key limitation of a simple drawn model is its inability to accurately represent the size differences of the planets compared to each other or to the Sun.
