Read the passage from "The Lady, or the Tiger.” The more we reflect upon this question, the harder it is to answer. It involves a study of the human heart which leads us through devious mazes of passion, out of which it is difficult to find our way.

She had lost him, but who should have him?

Which phrase from the passage most helps the reader analyze whether the princess chooses the lady or the tiger?
