The answer to this problem is Noun.
One way to show that a statement is not a good definition is to find a counterexample. A counterexample will show that there are more views on any subject.
Porphyria's Lover is a dramatic monologue that tells us the speaker's thoughts.
There is no conflict resolution: the poem ends with Porphyria dead by her lover's hand. No one has come upon them by the end of the poem and he has not been punished. What happens after this scene ends is unresolved.
There is no dialogue, either. The speaker of the poem tells us that Porphyria "calls" the speaker, but he does not relate her exact words. There is no dialogue in the poem.
Finally, there are no formal stage directions. The speaker does describe several actions happening during the poem -- as when the speaker tells us he strangles Porphyria with her hair -- but we do not have formal stage directions as one would get in a play.
