Which statement belongs in what I already know box?

There are many Gothic themes present in the story of Dr. Jekyll and Mr. Hyde. Gothic stories typically deal with themes of horror, supernatural elements, despair, death, evil, and other dark subjects. The story clearly deals with supernatural elements in that Dr. Jekyll and Mr. Hyde are the same person, which is physically impossible. It also contains elements of horror in the way that Mr. Hyde is described. It also contains themes of despair and dejection, as Dr. Jekyll grows weaker and weaker as Mr. Hyde grows stronger. Hope this helps.
