Can you please check these questions, Witeacher? Thank you.

1) Focus on Chapter 10 of Stevenson's Dr. Jekyll and Mr. Hyde and describes how Dr. Jekyll manages to separate his two identities.
2) What kind of narrative technique does Stevenson adopt?
3) In what way are Dr. Jekyll and Mr Hyde different?

In #1, it should be 'describe' (no -s).

Everything else is fine.
