Thank you very much. A few other things on sentences I need to check. They are really awkward to check.

1) Which of the following are possible?
The novels were told/written in the first or third person singular (?).
We have a first or third person narrator.
2) The author employed first person or third person narration.
3) When Robinson frees Friday, they start living together with a relationship master-slave.
Robinson gives a detailed description of his new companion: he is a good-looking, fascinating young man in his late twenties, he has got strong and well-built legs and arms and his skin isn't dark or yellowish but tawny.
4) He has sparkling eyes and a small nose, not flat as the one of the negroes, which contrasts with his round and plump face.
5) Moreover, even his hair isn't curly as the savages one but black and straight. Eantually Robinson says that he is pleased that Friday looks so much like a European.

1) Which of the following are possible?

Neither. You could ask the question with the "or" setup, but as a statement, you need to use one or the other:
The novels were told in first-person point of view.
The novels were told in third-person point of view.
This story is narrated from first-person point of view.
The book is narrated from third-person omniscient point of view.
