Okay so it asks you “how can people be both intelligent and foolish at the same time?”. One example could be Albert Einstein forgetting his own address. Look for characters in the story that are smart but can be foolish and/or have a lack of judgement.
The next question asks you “how the author shows Endor’s intelligence enabling him to fight against authority”. It seems Endor is intelligent and was fighting against authority in the story whether it be corruption or oppression find some examples of Endor standing up to authority. I hope i made a clear enough answer and i hope im not wrong.
