9. an intense contest between two hunters
The contest is between General Zaroff and Raisnford. General Zaroff loves the challenge of hunting difficult game. However, he has found that the only "game" smart enough to offer him a challenge any more are humans. Anyone that lands on the island is subject to Zaroff's desire to find a formidable foe. He finds this in Rainsford, a fellow expert hunter, whom he challenges, or rather forces, to be his prey.
10. Whitney tells Rainsford about the mysterious reputation of the island in the distance.
Suspense is created in the beginning by introducing a mysterious setting. The narrator ends up on this island that is called "Ship-Trap Island". It's name is rather fore-boding and indicates what will happen to any ship that comes to close.
