　　Questions 13-24 are based on the following passage.

　　The following passage is from a 1992 publication in which the author, a physicist, discusses "reality" and the models that human beings use to understand the universe.

　　Perhaps you've seen the painting: a pipe, depicted with photographic realism, floats above a line of careful script that reads "Ceci n’est pas une pipe"—"This is not a pipe." Rend Magritte painted The Treachery of Images in the 1920s, and people have been talking ever since about what it means.

　　Did Magritte intend to remind us that a representation is not the object it depicts—that his painting is "only" a painting and not a pipe? Such an interpretation is widely taught to college students, but if it is true. Magritte went to an awful lot of trouble—carefully selecting a dress-finish pipe of particularly elegant design, making dozens of sketches of it. taking it apart to familiarize himself with its anatomy, then painting its portrait with great care and skill—just to tell us something we already knew. In another canvas, The Two Mysteries, Magritte is even more insistent: the original pipe painting, complete with caption, is depicted as sitting on an easel that rests on a plank floor, but above that painting, to the left, hovers a second pipe, larger (or closer) than the painted canvas and its frame. What we have here is a painting of a paradox. Obviously the smaller pipe is a painting and not a pipe. But what is the second pipe, the one that looms outside the represented canvas? And if that too is but a painting, then where does the painting end?
