Which artwork depicts figures walking an impossible staircase?

Which artwork depicts figures walking an impossible staircase?

• A. Wyeth - Christina's World (1948)
• B. Gauguin - Where Do We Come From? What Are We? Where Are We Going? (1897-98)
• C. Escher - Ascending and Descending (1960)
• D. Dalí - The Persistence of Memory (1931)

Answer: (C)

This question tests your eye for impossible forms in art—the way perspective can trap the eye in a paradox. The artwork that fits this idea shows a staircase that appears to go on forever in a loop, with people walking up and down as if the space were ordinary, yet the geometry can’t actually exist. That is the signature trick of M. C. Escher’s Ascending and Descending: a single continuous staircase that forms an endless cycle, creating a visual paradox rather than a real, navigable structure. The figures marching along reinforce the sense that movement is possible, even though the architecture defies consistent geometry, making the scene unforgettable as an illustration of an impossible object. The other paintings present different subjects: one shows a solitary figure in a landscape, another poses a broad, narrative scene about life and time, and the last features melting clocks in a dreamlike setting. None of these center on an impossible staircase or the same kind of architectural paradox, so they don’t illustrate the concept the question is testing.
