A monkey is sitting expectantly in a laboratory, wearing earphones that keep its head in an upright fixed position. Its hand rests at its waist near a telegraph key that it can feel but can not see. Soon a green light begins to blink and the monkey 11 the key to signal that it is ready. Then it hears two syllables coming through the earphones, realizes that the syllables are different, and correctly lifts the key. This is not an amazing event in the field of research on primate behavior. Scientific studies on animal 12 have been conducted for many years. Chimpanzees, gorillas, and monkeys have all been taught to 13 messages from humans. What is new about this study is what the researcher noticed about the monkey’s use of its hands. Although either hand could have been used for pressing the key, everyone of the monkeys used its right hand. In other tasks, however, like grabbing food from a feeder or taking something that is offered to them, the monkeys seemed to have no 14 for one hand over the other. It has 15 been assumed that only humans have the trait of 16 one hand. The right hemisphere of the brain controls the left arm and hand, and the left hemisphere of the brain controls the right arm and hand. 17 mental abilities such as speaking and understanding language are handled by the left side of the brain, so it is thought that this produces a dominance of right-handed humans. However, a 18 number of researchers are challenging this notion that nonhuman primates have no hand preferences. They argue that these traits can be 19 back to primates living tens of millions of years ago. Their contention is that primates use their right hands to perform precise manipulations where they can not clearly see what they are doing. And then why haven’t 20 noticed this before It is difficult to set up experiments that require the kind of task where handedness is important. A. researchers B. doctors C. growing D. generally E. comprehend F. offer G. important H. preference I. traced J. followed K. behavior L. favoring M. presses N. shows O. strange

I have had just about enough of being treated like a second-class citizen, simply because I happen to be that put-upon member of society—a customer. The more I go into shops and hotels, banks and post offices, railway stations, airports and the like, the more I am convinced the things are being run solely to suit the firm, the system, or the union. There seems to be a deceptive new motto for so-called "service" organizations—Staff Before Service. How often, for example, have you queued for what seems like hours at the post office or the supermarket because there were not enough staff on duty to man all the service grilles or checkout counters Sure In these days of high unemployment it must be possible to hire cashiers and counter staff. Yet supermarkets, hinting darkly at higher prices, claim that uncovering all their cash registers at any one time would increase overheads. And the post office says we cannot expect all their service grilles to be occupied "at times when demand is low." It is the same with hotels. Because waiters and kitchen staff must finish when it suits them, dining rooms close earlier or menu choice is cut short. As for us guests, we just have to put up with it. There is also the nonsense of so many friendly hotel night porters having been thrown out of their jobs in the interests of "efficiency" (i.e. profits) and replaced by coin-eating machines which offer everything from lager to laxatives. Not to mention the creeping threat of the tea-making kit in your room: a kettle with a mixed collection of tea bags, plastic milk cartons and lump sugar. Who wants to wake up to a raw teabag I do not, especially when I am paying for "service." Can it be stopped, this worsening of service, this growing attitude that the customer is always a nuisance I angrily hope so because it is happening, sadly, in all walks of life. Our only hope is to hammer home our anger whenever and wherever we can and, if all else fails, bring back into practice that other, older slogan—Take Our Custom Elsewhere. Service organizations contend that keeping all checkout counters operated can result in ______.
