Final answer:
Option 2 is the best summary, explaining that the 'ultimate boon' in a hero's journey marks the climax and can take different forms, fitting into the context of both getting something and defeating a nemesis.
Step-by-step explanation:
The best summary of the information in step 11 is option 2, which reads, "Once completing the previous steps the hero gets the 'ultimate boon.' This boon can take many forms, either getting something, destroying something, or avenging someone." The term ultimate boon is a concept from Joseph Campbell's monomyth or the hero's journey, which represents the achievement of the goal of the quest. It's what the hero set out to obtain or achieve, and it marks the climax or turning point of the narrative. In the context of Harry Potter, defeating Voldemort and discovering the Sorcerer's Stone can be seen as Harry's ultimate boon. However, option 1 incorrectly summarizes the ultimate boon as it confuses the Sorcerer's Stone with defeating Voldemort, which are separate events in the series.
