Answer:
50-64
Explanation:
China is the nation with the largest population in the world, and that has been the case throughout all of the written history, and probably even before that. The country had very large birthrates, which was leading to rapid growth to the population. Because of that, there was even a law that restricted the families as to how many children they can have. Because of that law, the population of China started to gradually age, so the percentage of the younger age groups has been declining, while the percentage of the older age groups has been on the rise. This has led to the age group of 50-64 to account for 120 million people in China, a percentage that has grown almost twice compared to several decades prior to that.
There are actually 2 main theories for the Proto-Indo European language hearth. The Kurgan theory and the Anatolian hearth theory.
The Anatolian theory states that the Proto-Indo European language came from present day Turkey.
The Kurgan theory states that the Proto-Indo European language came from near the steppes of Russia.
The Caucasus Mountain Range covers those two areas described perfectly. The mountains are near Turkey and relatively close to the steppes of Russia as well.

Explanation:
Largest number of stars in our galaxy is located in a disk. They have nearly circular orbits around black hole which is located in a center of galaxy. Orbits of all these stars have same orientation. Some of orbits have small inclination which causes for stars to move little up and down.
Halo stars are located in a "bubble" around our galaxy. These stars travel high above and far below the disk on orbits with random orientations. These are stars that once were located in a disk but they went outside of it.
Bulge stars are located in a center of our galaxy. They also orbit black hole and they have much shorter period of orbit than all other stars in a galaxy. Their orbits have random orientations.
