Answer:
A. To demonstrate Equiano's lack of knowledge about European customs due to living in an isolated part of the continent.
Explanation:
Olaudah Equiano in the autobiography written by him demonstrated all the travails he went through while being transported across the Atlantic Ocean by the White men. In paragraph five, Equiano asked a series of questions to his fellow countrymen on board with him on the ship. He asked about the country of the white men, and if they had their own women. He also asked about how the vessel could go and was amazed when the workings of the vessel were explained to him.
All these show that Equiano had no knowledge of the European way of life because he had lived in Africa all his life.
