PrepTest 94+, Section 2, Question 25
According to the Newtonian theory of gravity, the gravitational force between two bodies depends exclusively on their mass and the distance between them, but is independent of what the bodies are made of. Thus, according to the Newtonian theory, one does not need a theory of the structure and constitution of the Sun and the planets in order to calculate their orbits.

The conclusion of the argument above follows logically if which one of the following is assumed?
Mass is dependent on gravitational force.
According to the Newtonian theory, the calculation of planetary orbits requires considering only their gravitational forces.
The Newtonian theory of gravity is mistaken about the data needed to calculate gravitational force.
Knowing what an object is made of is sufficient for determining its mass.
The gravitational force between the Sun and a planet is a factor in determining the distance between them.
