Read this excerpt from "Goodbye to All That" by Joan Didion. [New York City] was instead an infinitely romantic notion, the mysterious nexus of all love and money and power, the shining and perishable dream itself. To think of “living” there was to reduce the miraculous to the mundane; one does not “live” at Xanadu. Which statement best explains the impact that the allusion to Xanadu has on the meaning of the text? The allusion helps indicate that New York City, like the magical Xanadu of literature, was a place that looked appealing from afar but from which one could never escape after entering. The allusion helps stress the notion that New York City was, to Didion, a wondrous, fantastical, or mythical place for so long that encountering its everyday, ordinary, or humdrum realities was disappointing. The allusion helps show that Didion's time in New York City exposed her to cultural and literary experiences that allowed her to make relevant and accurate references to mythical cities like Xanadu. The allusion helps suggest that Didion, like a resident of the mythical and miraculous Xanadu, realized that she had finally arrived in the place where all of her dreams would come true.
