Answer 1

The two correct statements about stellar evolution are:

1. Average stars evolve more slowly than massive stars.
2. Massive stars evolve more quickly than average stars.

Massive stars go through their life cycles much more quickly than average (or lower-mass) stars due to their greater gravitational forces and higher temperatures, leading to faster nuclear fusion in their cores.
