What are two external and internal conflicts for the book all summer in a day?

External conflict: The children on Venus are conflicted with Margot's presence, as they are jealous of her because she remembers sunshine and they don't. This leads to them locking her in a closet when the sun finally comes out. Internal conflict: Margot struggles with feeling isolated and lonely because she is different from the other children, causing her to feel disconnected and longing for a world she can't fully remember.
