1- Why is it important for Lenina to publicly prove her unfaithfulness to Henry?
Because in the time that the book take place, the accion of infidelity doesn´t exist. What I mean to this, is that many people has more than one couple, but not for that reason he/she was unfaithful.
So, in conclusion, doesn´t matter if she make publicly her unfaithfulness to Henry because doesn´t exist a real meaning for that word, so if she make publicly this, she only was making it official. And a quote of this is in chapter 4, page 50 and says: "Anyhow, she was publicly proving her unfaithfulness to Henry. Fanny ought to be pleased, even though it was Bernard."
2- Is it natural to be in a couple and raise a family in the Brave new World? Why/why not?

3- What is the meaning of “pneumatic” when it is used to describe Lenina?
"Pneumatic" is used to describe the physical aspect of a person, and means that the person is sexy and curvy. In this case, this word is describing Lenina.
4- What is “Soma” and why do people use it?
"Soma" is a drug very effective because doesn`t have second effects, and is used to cure the unhappiness (making feel happy). In Brave New World, if you feel sad, is very normal to take this.
5- Was Bernard a tall or a short man? How did this affect his job? Please justify your answer by quoting from chapter 5.
Bernard wasn`t a tall man, and this is justified in chapter 4 that says:"I have stood eight centimeters short of the standard Alpha height and was slender in proportion". This affect his job because he felt observed by his coworkers for been different.
