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
