The three correct answers that provide evidence of universe expansion that supports the Big Bang Theory are:
- Galaxies are moving away from each other.
- An enormous amount of weak cosmic background radiation has been detected in the universe.
- The temperature of the universe is decreasing.
(Note: While the last option you selected about the temperature decreasing isn't as directly tied to the Big Bang Theory as the other two, you could potentially consider the Cosmic Microwave Background radiation as more significant evidence. Always double-check with your curriculum's context for the best match.)
However, if focusing strictly on the strongest evidence, the first and the second options are the most universally recognized indicators of the Big Bang Theory.

Responses
The temperature of the universe has warmed over time.
The temperature of the universe has warmed over time.
The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe has cooled and warmed repeatedly over time.
The temperature of the universe has cooled and warmed repeatedly over time.
The temperature of the universe has cooled over time.
Responses
The temperature of the universe has warmed over time.
The temperature of the universe has warmed over time.
The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe has cooled and warmed repeatedly over time.
The temperature of the universe has cooled and warmed repeatedly over time.
The temperature of the universe has cooled over time.
The statement that is evidence of universe expansion that supports the Big Bang Theory is:
The temperature of the universe has cooled over time.
This cooling is a consequence of the expansion of the universe since the Big Bang, leading to the current state of the Cosmic Microwave Background radiation.
