D) Sentence 4 because it is unrelated to the passage.
It's been a while. I'm assuming the girl is Lucy
Gatsby by had always wanted wealth and had possibly resorted to underhand means to achieve it.
Yet he would never be able to achieve old money, the type of wealth and fame accumulated over the years, and the same type that was cheated from him by the dead captain's relatives.
Gatsby also failed to get together with Lucy, the love of his life. He bought a mansion right across from her's and held parties hoping that Lucy might attend one of them. Yet he could never get together with her. Lucy still chose to stay with Tom, and Gatsby was fatally shot by Wilson before he could try again.
So. Old money. Love.
Gatsby suggests that her wealth is a defining and intrinsic aspect of Daisy's character.
What you can assume from someone having a "voice full of money" is that their wealth affects their being in a lot of ways, as deeply as their speech:
- thanks to access to education and literature, she probably has a varied vocabulary;
- because she was brought up in a respectable family, she probably was taught to use decent language and does not say any vulgarities;
- she probably has a lot of confidence due to her high social status, and speaks in a poised, assertive way.
