Answer 1

The universe is made up of 2 types of matter: **baryonic** matter, which is made up of atoms, and **dark** matter which is not. Fritz Zwicky hypothesized that galaxies inside the Coma Cluster were being held intact by **dark** matter. Scientists believe that galaxies would break apart if **dark** matter were absent, causing the structures of the galaxy to fall apart.

So the correct selections are:
1. baryonic
2. dark
3. dark
4. dark
