Answer:
B) determined
Step-by-step explanation:
The evidence of his determination appears here: "still he pressed on."
Rainsford is an athletic man: A man in less fortunate physical condition may have not endure the swim back through the unpleasant current to the island. Rainsford appreciates the accommodation of Zaroff's chateau, perceiving a large number of the decorations in the "medieval gloriousness" of his visitor's lounge area. He even observes that Zaroff's garments are made by one of London's best tailors, and he considers Zaroff a "genuine cosmopolite." Zaroff calls Rainsford "a fine young fellow of the informed class," yet Rainsford emphatically contrasts on Zaroff's boorish new style of chasing people: Zaroff thinks of it as brandishing, yet Rainsford calls it "murder." Rainsford shows his very own wily chasing abilities while filling in as Zaroff's prey, and he figures out how to execute Ivan and one of Zaroff's pooches before evading the Cossack and making his getaway.
