I had to look up the story you had the question about and its answer choices. Since you didn't show us the excerpt, Im not sure if this is the right story or not... If its not right, please send us the correct excerpt and ill gladly help you out!
The central idea should include the forces sent by the Cicones to stop the Odysseus and their "plundering" and how their men were skilled.
Again, if this is the wrong story, im sorry :/
