You chose: Arabella should stay the same and remain convinced that romances are true to life
In the novel, the climax of the plot occurs when Arabella's life is endangered by her folly and a doctor manages to persuade her that the way she sees the world is improper. By choosing to keep her folly and allow her to continue to be the same Arabella from the rest of the novel, you are diverting from the plot of the novel, but also providing a way for Arabella's plot to make more of a statement. Motooka points out that Arabella's folly makes her "a strong, independent, admirably spirited woman" and that her conversion leaves her "defeated, humiliated, and subordinated," so by eliminating that plot element, Arabella is, in one sense, made stronger (Motooka 251). Whether or not leaving Arabella in that state at the end of the novel would have been accepted popularly or even have been allowed to be written into Lennox's novel by her male advisors would have been questionable, however.
