Question

Numbers 13 and 14 I don't really understand them that well

Answer 1

What about them don't you understand? Agitatedly=angrily=irritatingly

Answer 2

To clear up 13 you have to understand the context of the knife, so that gives you the answer which would be in this instance "B." I would thus say this: Macbeth feels torn between guilt and temptation about the murder of Duncan. The dagger is a representation of the inevitability the he(Macbeth) will murder Duncan.
