In the story "the alchemist", when the boy tells the oasis chieftains about his vision, the leader tells a story about

a. joseph, the dream interpreter.
b. saint santiago matamoros.
c. narcissus from mythology.
d. a converted roman centurion.

Joseph, the dream interpreter.

Explanation:

The Alchemist's  book is a novel by Paulo Coelho. This novel got a good reception by  the public but it had bad critics and deeping analysis due to the sentences or parallelism in some texts with texts of the bible.

In fact some preachers have commented as introduction of theirs sermons.

(This is a another subject to discuss).  

Certainly the comments of the old man ( center of chieftains) for Santiago ( The young pastor) was about a man who believed in dreams and was sold as slave (For inference this is Joseph the son of Jacob).

different strategies reach different people based on their ability to understand the material. (from personal experience) when writing an argumentative essay write explaining the subject as though your audience never heard of it before and it is just being introduced, then explain why other people hate it also, afterward you would explain why that would be wrong. i hope that : )
