Answer: So I'm not sure about page numbers, it being that we may have different books, but the symbolism is explained below.
Explanation:
Symbolism, from litcharts.com: The hill, for Jonas, represents a gateway to Elsewhere.
I know this because: Riding a red sled down the hill is his first memory and his first awareness of the color red. It signifies his realization that outside his community there is a world not dominated by Sameness.
Hope this helps!
