In 'brave new world', what is the purpose of the hatchery and conditioning center?

The hatchery  in brave new world is used as a human reproduction center. Since none of the birth occurs naturally in that society, They combine human's embryos with various type of chemicals to form the type of babies that they want.

The conditioning center is used in order to teach the children about their adult roles in the future.  For examples, the babies that are intended to work as factory workers would be conditioned to hate book since the early age so they become suited to hard labor.

i feel as if they would both catch on before to long because they would see them to frequent

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
