Answer 1

Rose of Sharon’s pregnancy holds the promise of a new beginning. When she delivers a stillborn baby, that promise seems broken. But rather than slipping into despair, the family moves boldly and gracefully forward, and the novel ends on a surprising (albeit unsettling) note of hope. In the last few pages of his book, Steinbeck employs many symbols, a number of which refer directly to episodes in the Bible. The way in which Uncle John disposes of the child’s corpse recalls Moses being sent down the Nile. The image suggests that the family, like the Hebrews in Egypt, will be delivered from the slavery of its present circumstances.
