Answer 2

Same age stars is a mark of Galaxy formed by collapse

Step-by-step explanation:

Before a galaxy can be formed, the materials that help in building the galaxy rotate at a speed, it's the come together and collapse by it self due to it's gravitational pull. When it's collapse globular are formed and it's away from it's nucleus. The clusters this give rise Halo stars which are stars of the same age.
