Answer 1

The three correct answers that provide evidence of universe expansion supporting the Big Bang Theory are:

1. An enormous amount of weak cosmic background radiation has been detected in the universe.
2. Galaxies are moving away from each other.
3. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.

These pieces of evidence collectively support the Big Bang Theory by demonstrating the aftermath of a hot, dense state followed by expansion and cooling.
