Question

Students want to make a scale model of the Earth and Moon system that shows correctly-scaled sizes and distances. Here are some guidelines they have to follow.

It has to be shown in the classroom, and the classroom is 51 square meters in area.
It has to be easily moved around since orbital motion and rotations will be shown.
It cannot cause damage if it is dropped.
All the students in the class should be able to see it from their desks.

Four different students came up with different designs. The designs and characteristics are shown in the table below.

Which design best satisfies the criteria and constraints of this Earth-Moon model?
A.
design 1
B.
design 3
C.
design 2
D.
