If a Chinese asks you 你是不是一个呆子? What do you say? (This was given by my mandarin teacher, once it was given the Asian kid started laughing what do I do?!)

It means 'Are you a fool?'.

Respond to this message with your response and I will translate it for you if you wish.

Hope that helped!!! k

explanation: the line "to save the day, harry must get past a scary three-headed guard dog" from the summary best justifies the conclusion that harry potter and the sorcerer’s stone was influenced by ancient greek mythological literature. the three other choices had nothing to do with ancient greek literature - and the words "three-headed guard dog" are what makes that choice the correct answer.
