Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Patrick Foley is dying of cancer and decides to return to the outback where he was born. He has stopped taking his medicine and is at peace with his decision to die alone in the woods. On his journey, he notices a family camping.  From a neighbouring peak, Foley watches as Shawn, a 10-year-old boy, begins collecting firewood.  The father attempts to move the camper away from the edge.  Unfortunately, the camper rolls off the cliff and crashes to the bottom of the cliff with Shawn's parents inside.  Shawn climbs down from the cliff finding the camper crushed upside down and realizes his parents are dead.  Foley has an ethical dilemma: take the stranded ten-year-old back to civilization, and lose his own wish to die where he was born, or continue his personal mission and let the boy die alone in the wilderness.  He decides to take the boy with him, and teaches him along the way how to survive in the wilderness. A striking moment is teaching the boy to tickle trout in a stream with your fingers, to lull them to be caught. A strong bond grows between the two, and when Foley finally dies, Shawn is equipped to travel out of the outback alone.
A:
What does the man who wants to die along in the woods teach the 10-year-old to tickle trout in order to do?
