Planets orbit the Sun because _____.

This is a poorly written question.

<span>Out of the choices listed, the first one is the only one that includes
a true statement ... the greater the mass of two objects, the greater
the gravitational attraction is between them.</span> 

-- Newton's law of universal gravitation doesn't "suggest" that.  It states it ...
boldly and unequivocally.

-- The law doesn't refer to the "greatness" of the mass of the two objects. 
It refers to the product of their masses.

-- It's true that the law of universal gravitation can be massaged and
manipulated to reveal the existence of gravitational planetary orbits.
But there's a lot more to it than simply the masses.

For example ... the gravitational force between two objects is inversely
proportional to
                           (the distance between the objects)² .

It turns out that IF that exponent were not precisely, exactly  2.000000... ,
then gravitational orbits could not exist.

Setler [38]

<u>Answer:</u>

Option: D. Gravity is pulling the crash test dummy in the direction the car is moving.

<u>Explanation: </u>

When a car accelerates from a standing start, the crash test dummy appears to be pressed backward into the seat cushion because the gravity is pulling the crash test dummy in the direction the car is moving.  

Basically when the car is starting, the person inside is in static position and the car is going to move. So it is putting a force on the person to move on the same speed. But as the person is sitting static hence gravity is pulling him behind from moving. Hence, The dummy appears to be pressed backward.
