15. a) In this novel the author used symbolism in many ways, one of the main symbols in the novel is Chris McCandless yellow Datsun car. In the beginning of his journey he planned to drive this car all the way to Alaska, these plans change as his car breaks down. Instead of getting it fixed or calling for help he left it, “With the battery dead there was no way to get the Datsun running...McCandless had no choice but to walk…” (Krakauer, 28) This represents Chris cutting his ties with the regular society and his independence.
