The two items that provide evidence supporting the Big Bang theory are:
1. **Cosmic background radiation** - This is a remnant radiation from the early stages of the universe and is a key piece of evidence for the Big Bang theory.
2. **Composition of matter in the universe** - The observed ratios of light elements (like hydrogen, helium, and lithium) match the predictions made by the Big Bang nucleosynthesis model, which supports the theory.
The other two options, while related to cosmology, do not directly provide evidence for the Big Bang theory.
