Answer 1

Answer:

The oldest stars in spiral galaxies are younger than the oldest stars in elliptical galaxies.

Explanation:

Spiral galaxies have a greater star formation than elliptical galaxies, since the latter contain less gas and dust. Therefore, the rate of creation of new stars is lower in elliptical galaxies. These galaxies are dominated by old stars, with a long evolution. While the spiral galaxies have stars with a faster evolution.
