Can someone check these questions, please? Thank you in advance

In Shelley's Frankenstein, what are the traits that remind us of a Gothic novel?
2)Discuss the concepts of beauty and youth as portrayed by Lord Henry in chapter 2 of O. Wilde's The Picture of Dorian Gray.
3) Describe and explain the kind of imagery used in R.L. Stevenson’s Dr Jekyll and Mr Hyde to describe the duality of man's nature. (Max. 10 lines)

Yep, I checked the questions. They look legitimate.
