Read the excerpt from "How a Cat Played Robinson Crusoe.”
 Something had rustled the grass heavily, and she trailed it,
 expecting a particularly large, fat marsh mouse. When she
 pounced upon an immense old ship's rat, she got badly bitten.
 Such an experience had never before happened to her. At first
 she felt so injured that she was on the point of backing out and
 running away. Then, the fire of far-off ancestors awoke within
 her. She flung herself furiously into the fight, and the struggle
 was soon over.
 Which type of conflict does the cat face? 
 Individual versus individual 
 Individual versus self
 Individual versus nature 
 Individual versus society
