Answer: The answer is given below.
Explanation:
Fear simply means when one is afraid of a partial thing that can either cause harm, or pain.
The allure of fear is due to the fact that when one is afraid, the person is under intense pressure as the person won't know the next thing that'll happen to him or her and there's a particular adrenaline that the person will feel. This can be seen from the literature where Usher stated that he's afraid of the results of the events that'll occur in the future and thesame thing was said by Roderick as well.
The thing I've learned from this story about portrayal of fear in literature is that fear is a result of the fact that we don't know what will happen as we don't know if the outcome of an event will be favorable, harmful, painful etc, hence, we also feel a particular pressure which makes us afraid.
