Final answer:
Pi is emphasizing the absurdity of expecting something remarkable in a common, everyday setting like a Mexican tropical jungle.
Step-by-step explanation:
In the book The Life of Pi, when Pi says, "And they expected to find—ha! In the middle of a Mexican tropical jungle, imagine!" (Chapter 10), he is emphasizing the absurdity of expecting something remarkable in a common, everyday setting like a Mexican tropical jungle.
Pi finds it amusing and ridiculous that people would have unrealistic expectations in such a remote location. By using sarcasm and disbelief, Pi highlights the contrast between the expectations and reality.
