Do animal lie The biologists note that by our strict standards, animals are poor liars. Yet a great many animals—from the lowliest animals to the cleverest animals—use false information to direct the behavior of others. Deception (欺骗，诡计), in fact, is a common part of social interaction among almost all higher animals. The more intelligent an animal is, the more calculated (算计的) and considered its lies. Some biologists even say that one of the reasons we humans evolved (进化) such large brains was to improve our ability to tell lies and to better recognize the lies to others. A song that was popular in the seventies says, "You can’t hide your lying eyes." But it is not often the case. Some people may be trained to detect their lies and make them hard to be discovered. The sentence "You can’t hide your lying eyes" in the last paragraph means: ______.
A. You can’t tell a lie B. Your eyes are telling a lie C. Your eyes will betray (出卖) your heart D. You can’t tell a lie without closing your eye
