【必答問題 5 日常使う物のデザインをする際には標準化 (standardization) という方法がある。 という内容に続く次の英文を読んで、あとの問いに答えよ。(配点44) If we examine the history of advances in all technological fields, we see that some improvements come naturally through the technology itself, while others come through standardization. The early history of the automobile is a good example. The first cars were very difficult to operate. They required strength and skill beyond the abilities of many. Some problems were solved through automation. Other aspects of cars and driving were standardized through the long process of international standards committees: . On which side of the road to drive (constant within countries) country, but variable across On which side f the car the driver sits (depends upon which side of the road the car is driven) -The (2) of essential components: steering wheel, brake, clutch, and accelerator (the same, whether on the left- or right-hand side of the car) Standardization is one type of cultural constraint. With standardization, once you have learned to drive one car, you feel confident that you can drive any car, anyplace in the world. Standardization provides a major breakthrough in usability. I have enough friends on national and international standards committees to realize that the process f determining an internationally accepted standard is laborious. Even when all members agree on the merits of standardization, the task of selecting standards becomes a long, political issue. A small company can standardize its products without too much difficulty, but it is much more difficult for an industrial, national, or international body to agree to standards. There even exists a standardized procedure for establishing national and international standards. organizations works on standards. First, a set of national and international Then when a new standard is proposed, it must work its way through each organization's approval process. Standards are usually the result of a *compromise among the various competing positions, which can often be an inferior compromise. Sometimes the answer is to agree on (4 ). Look at the existence I both metric and *English units; of left-hand- and 18 right-hand-drive automobiles. There are several international standards for the *voltages and *frequencies of electricity, and several different kinds of electrical plugs and sockets- which cannot interchanged. With all these difficulties and with the continual advances in technology, are standards really necessary? Yes, they are. Take the everyday, clock. It's standardized. Consider how much trouble you would have telling time with a backward clock, where the hands revolved "counterclockwise." A few such clocks exist, primarily as humorous conversation pieces. When a clock truly violates standards, such as (the one in Figure 1, it is difficult to determine what time is being displayed. Why? The logic behind the time display is identical to that of conventional clocks: there are only two differences - the hands move in the opposite direction (counterclockwise) and the location of "12," usually at the top, has been moved. This clock is just as logical as the standard one. It. bothers us because we have standardized on a different scheme, on the very definition of the term clockwise. Without such standardization, clock reading would be more difficult: you'd always have to figure out the "mapping. E) compromise *metric メートル法の *English units イギリスの計量法(ヤードボンド法) *frequencies of electricity 電気の周波数 voltages E *mapping 対応づけ (2つのものの間の関係を意味する専門用語) 問1 下線部(1)の内容を、 同じ段落の自動車の例に基づいて30字以内の日本語で答えよ。た だし、句読点も字数に数える。 問2 本文中の空所 (2) に入る語として最も適当なものを、次のア~エのうちから一つ 選び 記号で答えよ。 7 color イ location ウ price I sight (239) 問3 第2パラグラフ (Standardization is one type of ...) について 次の Question に対す る Answer となるように、空所に入れるのに最も適当なものを,次のア~エのうちから一 つ選び、 記号で答えよ。 Question: What is "a major breakthrough in usability" provided by standardization?

Dogs won't give food to a human, even if that person gave them some food first, and that they would help other dogs that had helped them before. Therefore, the team Previous studies have shown that dogs can recognize cooperative and uncooperative humans, "reciprocal altruism"- that is, doing a good thing in return to a human who had given expected to find that their test subjects would put these two things together and show To start, the team trained a group of 37 dogs to press a button which would activate a them food first. *enclosure with the dispenser, while one of (2) two humans was in a separate enclosure with the button.

After that, the researchers switched over the button and the dispenser. They expected that the dogs would press the button to give food to the helpful human but not to the though the dogs did press the button, they did it just as often when either human had the food dispenser, and even when no human was there at all. "In these kinds of studies (5) [perform / to / dogs / which/ trained / are in a particular behavior for an experiment, they will usually do the behavior a few times as they have simply learned the association between the behavior and getting a reward, and it may be enjoyable for them to do the behavior," said Jim McGetrick, a PhD student at the University of Veterinary Medicine in Vienna who led the research. 身を正しく が本冊子 1番 2 次の英文を読んで下の設問に答えなさい。 (3) giving us some food?

McGetrick believes there is possible that the dogs did not understand enough about the task to realize that only one of the humans was providing them with food," he said. It could also be because they didn't fully understand the button and dispenser system, or because they were too focused on the food to notice whether a particular human was pressing the button or not. "Having said all that, even if they did completely understand the task and were fully attentive to the actions of the humans, there is still a good possibility that they wouldn't have given food back in return," he added. "It could be that providing food to a dog as they do not typically do that in everyday life."
