cosmic background radiation

Answer 1

The two items that provide evidence supporting the Big Bang theory are:

1. **Composition of matter in the universe** - The abundance of light elements, such as hydrogen and helium, is consistent with predictions from the Big Bang nucleosynthesis.

2. **Cosmic background radiation** - The cosmic microwave background radiation is a remnant from the early universe and is one of the strongest pieces of evidence supporting the Big Bang theory.

So, the correct items are:

- Composition of matter in the universe
- Cosmic background radiation
