Explanation: The poem "After Apple Picking" by Robert Frost Summer  is different from "The Corn Harvest" by William Carlos Williams because "The Corn Harvest," Williams writes in the third person, which implies he is a spectator of the scene he describes. "After Apple Picking," Frost uses the first person point of view, so it is the narrator who has taken part in the apple-picking.
