Let's build the stack from top to bottom. Math is above History. History is above Literature. Literature is above Science. Science is directly below Art (meaning Art is above Science, fitting right on top of Literature). The full order from top to bottom is: Math, History, Literature, Art, Science. Thus, Science is at the bottom.
