Final answer:
The statement about Rainsford realizing General Zaroff's intentions to prolong the hunt by leaving him in the tree is true, as seen in 'The Most Dangerous Game'.
Step-by-step explanation:
The statement that Rainsford realizes that General Zaroff left him in the tree on purpose so that he can continue to hunt Rainsford for another day is true. This occurs in the story “The Most Dangerous Game” by Richard Connell, where the sophisticated hunter General Zaroff hunts humans for sport. By intentionally allowing Rainsford a lead, Zaroff is prolonging the hunt to relish the challenge, as he finds it more thrilling than a quick and easy kill.
