Final answer:
The student's question pertains to a character named Garrison in the book 'Book Scavenger' by Jennifer Chambliss Bertman. The provided references about queer culture and figurative art in the San Francisco Bay Area are not related to this fictional character's story. To answer accurately, one would need to refer directly to the book 'Book Scavenger.'
Step-by-step explanation:
The question about when Garrison moved to the San Francisco Bay Area is from the book Book Scavenger. The book tells the story of a young girl named Emily, who moves to San Francisco and finds herself involved in a citywide book-tracking game.
The character Garrison Griswold is the creator of the game and a central figure to the plot. However, it appears there may be some confusion as the question is referencing Garrison, but the provided information relates to the history of queer culture and figurative art in the San Francisco Bay Area, which are not relevant to Garrison's story in Book Scavenger. To provide an accurate answer to the question regarding Garrison's move, it would be necessary to refer directly to the text of Book Scavenger by Jennifer Chambliss Bertman, rather than the provided reference materials which do not pertain to this particular narrative.
