Final answer:
The text snippets do not mention Santiago or the marlin, but in 'The Old Man and the Sea', Santiago wants the marlin to stop jumping to conserve its strength and avoid escape or shark attacks.
Step-by-step explanation:
The provided text snippets do not directly address why Santiago wants the marlin to stop jumping. However, based on the context of Ernest Hemingway's novel The Old Man and the Sea, Santiago wishes the marlin would stop jumping to conserve its strength. Every jump the marlin performs increases the risk of it breaking free or being attacked by sharks. In the book, Santiago is portrayed as both respectful of the marlin's struggle and desperate to catch it as a way to break his unlucky streak and reassert his skill as a fisherman. The marlin's jumping could potentially lead to the loss of Santiago's prey, which he cannot afford both for his pride and his sustenance.
