Human beings can see the spatial relations among objects by processing information conveyed by light. Scientists trying to build computers that can detect spatial relations by the same kind of process have so far designed and built stationary machines. However, these scientists will not achieve their goal until they produce such a machine that can move around in its environment.
Which of the following, if true, would best support the prediction above?
(A) Human beings are dependent on visual cues from motion in order to detect spatial relations.请教：from motion是修饰cues, 还是修饰human beings,如果是前者，那么选项的意思是事物在动，人是没有说在动，那么如何加强预言？这样和B选项不分高下啦？所以肯定是将人在动，但是语法上看，很牵强啊！？多多指教！
(B) Human beings can often easily detect the spatial relations among objects, even when those objects are in motion.
(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
(D) Although human beings can discern spatial relations through their sense of hearing, vision is usually the most important means of detecting spatial relations.（A）
(E) Information about the spatial relations among objects can be obtained by noticing such things as shadows and the relative sizes of objects.

From the phrase with red, we may safely reach that the motion should modify machine to yield a sensable meaning.
