Writacher, I didn't revise these questions. Though they can be improved, I can't see anything wrong with grammar.
1) Provide a description of Friday as given in Chapter 16 of Defoe’s Robinson Crusoe.
3) Outline the main features of 18th-century novels. Refer to the kind of narrator, then to the writer’s aim, the hero, time and place setting and finally to the role played by the reader.
The only changes I'd make are these:
- add a comma after "setting" in the second sentence.
- use "point of view" in place of "kind of narrator" if you are expecting the answer to include "first person" or "third person," etc.
