GDP, which we use right now, to see how many people have jobs, at what income, to decide how good the economy is. We could possibly use population density, as poorer countries/less developed countries tend to be more dense all around. Mainly economic things though, so GDP, income per capita. We use life expectancy, rate of literacy, freedom index..hope this helps
Inertia
Inertia is the property of a body of matter. It is described in Newton’s first law that an object will tend to remain at rest or move in a straight line at a constant speed unless a force acts on the object. The higher the mass of an object the higher its inertia.
Explanation:
In the vacuum of space, this is certainly evident because a celestial mass like an asteroid can move in a straight line for over billions of light-years with more or less the same speed unless another force of the universe such as gravity and dark energy act on this object. The reason this is less evident on earth is due to gravity and air resistance of the atmosphere that will quickly reduce the speed on an object and change its trajectory.

Answer:
it is actually 75% I Don't know why it is not in the options

The distance among two celestial bodies is measured in the unit of light year is false because Distances between galaxies and suns are measured by light years with suns and distances to extra solar planets. The larger astronomical unit i.e. A.U. is 149 598 000 kilometers
