Macbeth and his wife had a nice relationship until he encountered the witches who prophesied his kingship. His wife then urged him to kill King Duncan so she would be queen and he king. This of course was desfavorable for both of them. The relationship they have after becoming king and queen is less warm and emotionally penetrating. Macbeth became an old shell of a man (sociopath) while his wife became a lunatic. Things between them wasn’t as they used to be when they had a less social standing.
"Women have increasingly attained higher levels of education and experienced....." This best illustrates the influence culture has on traditional female roles. As the world changes, so does culture. Women do not think to just stay at home and have a domestic life, they now think for themselves and get higher education to get the job they want. Culture has changed and instead of women staying at home, they look for work. This shows how much the traditional female role has changed.
In lines 29-34 Shylock gives his reason.
"Yes, to smell pork; to eat of the habitation which your prophet, the Nazarrite, conjured the devil onto! I will buy with you, sell with you talk with you, walk with you and so following; but I will not eat with you, nor pray with you."
Shylock's reasons are to do with his own religious beliefs.
