I believe what this passage foreshadows is that C. Rome will suffer danger and destruction. You can see in the excerpt that no good things are happening - there is a fire, and something is burning, and people are afraid - so obviously, it doesn't mean that it is going to prosper or be renewed, when something so terrible is happening. One slave cannot destroy an empire, which is why that is incorrect too.
Alliteration is a close grouping of the same sounds, e.g. "the sweet soft sounds". The only solution that qualifies here is B - "feisty friends". Hope that helps :)
