Twins+discussion

What does this scene do? What is the scene's purpose? How is this scene constructed?
 * Brings up the topic of the Bokanovsky twins and why not all people are alphas
 * describes the reasons behind the need for different social classes
 * Shows John's hatred for the twins idea and how he does not agree with bottling
 * introduce the Cyprus project
 * give the reasoning behind a main concept of this world(the twins)
 * explains why epsilons need to be lower caste than the rest of the people
 * explains why not everyone can be an alpha
 * clears up the reader/john's questions on why people are bottled and decanted instead of being born naturally and allowed to choose their own jobs and path
 * through a conversation between john and mond
 * Through John's personal interactions with the twins
 * Through the results from the study
 * Could have been done earlier in the book but Huxley leaves all the answers till the ending of the book instead so the reader can form their own ideas and assumptions
 * Could have been just John's point of view but with the controller giving an explanation from the new world's point of view it adds contrast to the argument and questions the readers own assumptions on why this world performs the way it does
