How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span 'Both DNA and RNA are able to mutate. In fact, RNA being unstable, mutate at a faster rate. Consequently, viruses having RNA genome and having shorter life span mutate and evolve faster.' directly contains both statements: RNA mutates faster (Statement I) and RNA viruses with shorter lifespan mutate and evolve faster (Statement II).
