Question

In act 1, scene 5, the young scrooge's beloved ends their relationship. she says, "have i not seen your nobler aspirations fall off one by one, until the master-passion, gain, engrosses you?" from this dialogue, what can you conclude is her reason for rejecting him?

Answer 1

From this dialogue, we can conclude that she rejected him because he is too interested in money.
She says that 'passion' is his master now, and that it engrossed him - the word passion here refers to greed, not any romantic feelings. He became in love with his money rather than her, which is why she broke up with him. His life started spiraling at that moment, until he actually became the Scrooge.
