Answer to Question 1

As the Sun gets older, it converts more of its hydrogen to helium. As the He content increases, the sun's core becomes denser. This density change leads to a higher temperature within the sun, causing nuclear fusion within the core to proceed faster. The faster rate of fusion leads to a greater luminosity.

Answer to Question 2

Answers should mention United States' involvement, refugees, and ethnic conflict.
