<h2>Right answer: It is used to measure long distances in space</h2>
A light year (
) is a distance unit that is approximately
.
By definition it is <em>the distance that a photon would travel in vacuum during a Julian year (365.25 days) at the speed of light (299 792 458 m/s) at an infinite distance from any gravitational field or field magnetic.
</em>
<em>
</em>
In other words:
It is the distance that light can travel in a year.
This unit is used to measure large distances in space. Therefore the correct answer is D.

You didn't say kilo-WHAT. Beverages are often packaged in containers of 2 kilo-MILLILITERS, but not of 2 kilo-METERS or kilo-HERTZ or kilo-GRAMS.
There are a couple of answers to this:
A: A lot of people back then were heavily Catholic, the Catholic church claimed that the Earth was flat, while others believed the Earth was round.
B: Back then, obviously they didn't have airplanes or satellites, thus people believed the Earth was flat. The reasoning of this is because, if you were to look outside right now, the Earth does look like it could be flat. (that is because you have to be at a certain level of elevation to see the curvature of the Earth). Eventually though, people started reasoning and came to the conclusion the Earth was round. (They were proven right when aerospace technology came around.)
<span>South American countries have been attempting to mirror the free market system of the United States since around 1980 (the "Washington Consensus"). This has lead to economic stagnation in these countries. In order to boost their own economies, they are now looking at the models of more productive nations whose economies are growing very rapidly and are attempting to mirror their market systems. The main countries being scrutinized are China and India, who have nationalized many of their industries/resources. This would explain the shift.</span>
