The two items that provide evidence supporting the Big Bang theory are:
1. **Composition of matter in the universe** - This supports the Big Bang theory through the observed ratios of elements, particularly hydrogen and helium, which align with predictions from the theory of Big Bang nucleosynthesis.
2. **Cosmic background radiation** - This is perhaps the most significant evidence for the Big Bang theory, as it is the remnants of the heat from the initial explosion, detected as a uniform background radiation throughout the universe.
So, the correct answers are **composition of matter in the universe** and **cosmic background radiation**.
