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.
