Choose the best word(s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1 (10 points) The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, _1_ this is largely because, _2_ animals, we stand upright. This means that our noses are _3_ to perceiving those smells which float through the air, _4_ the majority of smells which stick to surfaces. In fact, _5_, we are extremely sensitive to smells, _6_ we do not generally realize it. Our noses are capable of _7_ human smells even when these are _8_ to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, _9_ others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate _10_ smell receptors in the nose. These receptors are the cells which sense smells and send _11_ to the brain. However, it has been found that even people insensitive to a certain smell _12_ can suddenly become sensitive to it when _13_ to it often enough. The explanation for insensitivity to smell seems to be that the brain finds it _14_ to keep all smell receptors working all the time but can _15_ new receptors if necessary. This may _16_ explain why we are not usually sensitive to our own smellswe simply do not need to be. We are not _17_ of the usual smell of our own house, but we _18_ new smells when we visit someone elses. The brain finds it best to keep smell receptors _19_ for unfamiliar and emergency signals _20_ the smell of smoke, which might indicate the danger of fire. 1. A although B as C but D while 2.

Indeed, if he has a reputation for slacking, you might even be outraged. Such behaviour is regarded as “all too human,” with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. But a study by Sarah Brosnan and Frans de Waal of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that it is all too monkey, as well. The researchers studied the behaviour of female brown capuchin monkeys. They look cute. They are good-natured, co-operative creatures, and they share their food readily. Above all, like their female human counterparts, they tend to pay much closer attention to the value of “goods and services” than males. Such characteristics make them perfect candidates for Dr. Brosnans and Dr. de Waals study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to exchange pieces of rock for slices of cucumber. However, when two monkeys were placed in separate but adjoining chambers, so that each could observe what the other was getting in return for its rock, their behaviour became markedly different. In the world of capu
