What is the exposition in Alibaba and the forty thieves?

Since the exposition is the point of the story where background that is crucial to the understanding of the story is given, I'd say that in this work, it'd be at the beginning, when it is revealed to the readers that Cassim is rich and greedy, while Alibaba is humble but poor. This provides background information by letting the reader know the two different lives and personalities of both characters who could've ended up surviving at the end of the story. However, because the reader now knows that Cassim is rich but greedy, the reader can now anticipate Cassim's death and Alibaba's wealth.
