Question: Why is the sky blue?
Answer: The light from the sky is a result of diffuse sky radiation which results in a light blue color being perceived by the human eye. On a sunny day the earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It can turn a multitude of colors such as purple (especially near sunset and sunrise) and black at night. Scattering effects also partially polarize light from the sky.

Answer to Your Question: "Why does the US invade other countries?"
The country's extraordinary rate of incarceration is largely due to changes in sentencing and drug policies. Though it has been abolished in most Western nations, capital punishment is sanctioned in the United States for certain federal and military crimes, and in thirty-eight states.
^Not sure that was a fair question...
This one was pretty suprising:
Is no your answer to this question?"
This depends on the context, as do several other possibilities: Sometimes "I don't know" is an acceptable answer, sometimes even a right answer. The same is true of "None of the above" and "There is no answer". An answer is the, or a, right answer, if it presents true information which falls within the determined range of alternatives. Questions of this simplest sort usually begin with Who, what, which, where, when, does/do, is/are.
