According to this society, what are the things that make george and his son and people like the ballerinas so dangerous? Cite textual evidence to support your inference.
Answer:
Intelligence, beauty, skills, and any personal trait that could make others feel jealous are seen as dangerous in this dystopian society.
Explanation:
We soon learn that people with above-average intelligence, like George and his son, are forced to wear a radio that sends "sharp noise to keep people like George from taking unfair advantage of their brains." This seems to be a strategy aimed to guarantee an equal society. In the same way, ballerinas have their beauty hidden under "sashweights and bags of birdshot" as well as masks in their faces to avoid other´s feeling ugly in comparison.
