The theme developed is the lack of opportunity for slaves to develop their talents. This theme is developed through the punishment of George, for having an innovative idea.
Explanation:
George is a slave. However, his condition as a slave does not allow him to develop his talents and knowledge, being constantly humiliated and violated by his "owner" who, in addition to not accepting George's intelligence, causes extremely aggressive and unjust punishments.
George has a great talent for engineering, creating pieces that reduce and improve some activities that are difficult to do. With that, the text deals with the theme of how slavery prevented us from having brilliant people working for the good of society. This is because many slaves had admirable skills in different branches, but never had the opportunity to develop their extraordinary gifts and abilities.
George is an intelligent and innovative young man who happens to be the slave of a cruel, petty one – Mr. Harris. George is talented and inventive. When he’s sent to work in a bagging factory, he invents a labor saving machine for cleaning hemp, which revolutionizes the way the factory works. Unfortunately, his "master" is jealous of George’s abilities and uses George’s intelligence as an excuse to punish and humiliate him. George functions in the novel as an example of a creative young man who would make a great citizen in a democratic society but who is kept down by the institution of slavery. His bitterness and anger about his situation, and his difficulty accepting Christianity, make him another important foil to Uncle Tom. For modern readers, George’s active rebellion is easier to understand than Tom’s more passive faith. The theme that id developed through George's attitude towards America is the questioning of slavery.
I think that the best answer for this is A. Because he knew that the coldest snaps never froze these springs, and he knew likewise their danger. So in the end he knew they were traps. I hope this helps ;) you are welcome.
