[填空题]Passage Two

Some rituals of modern domestic living vary little throughout the developed world. One such is the municipal refuse collection, usually once a week, your rubbish bags or the contents of your bin disappear into the bowels of a special lorry and are carted away to the local tip. To economists, this ceremony is peculiar, because in most places it is free. Yes, households pay for the service out of local taxes. (71) Yet the marginal cost of rubbish disposal is not zero at all. The more people throw away, the more rubbish collectors and trucks are needed, and the more the local council has to pay in landfill and tipping fees.

[单项选择]Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints-ways of feeling, thinking, and acting that "come naturally" in archetypal situations in any culture. Our "frailties" --emotions and motives such as rage, fear, greed, gluttony, joy, lust, love--may be a very mixed assortment, but they share at least one immediate quality: we are, as we say, "in the grip" of them. And thus they give us our sense of constraints.

C. a diagnostic test for separating biologically determined behavior patterns from culture- specific detail
D. a practical method for resisting the pressures of biologically determined drives
