Most people talk about the "five" senses of man. And it is true that we get our information about the outside world from our senses of sight, hearing, smell, touch and taste. Researchers tell us that sense of sight -- our visual (视觉的) sense -- gives us up to eighty percent of what we know about the world outside our bodies; while the other senses, the auditory(hearing), the olfactory(smell), the tactile(touch), and the gustatory(taste) bring into our brains information about the other 20% of what is happening. But there are two other senses that we cannot get along without it, though they are seldom noticed. These are the sense of balance, without which we would act like a drank man, and the kinetic(运动的) sense, which gives us our ideas about our own motion(行动).

A. about 80% of our information about the world
B. about half of our information about the world
C. about 20% of our information about the world
