rough rough ROUGH draft of thesis:

thank you so much, i am soo grateful!

Answer 1

It can be smoothed out:

In How the Garcia Girls Lost Their Accents, by Julia Alvarez, the Garcia sisters are continuously faced with injustice -- at their arrival in America, and by their father, men, and Americans in general -- and they are forced to change their morals to fit the American lifestyle.
