单选题{{B}}Passage 1{{/B}} Let us assume, for the moment, that labor m not prepared to work for a lower money-wage and that a reduction in the existing level of money-wages would lead, through strikes or otherwise, to a withdrawal from the labor market of labor which is now employed. Does it follow from this that the existing level of real wages accurately measures the marginal disutility of labor? Not necessarily. For, although a reduction in the existing money-wage would lead to a withdrawal of labor, it does not follow that a fall in the value of the existing money-wage in terms of wage-goods would do so, if it were due to a rise in the price of the latter. In other words, it may be the case that within a certain range the demand of labor is for a minimum money-wage and not for a minimum real wage. The classical school has tacitly assumed that this would involve no significant change in their theory. But this is not so. For if the supply of labor is not a function of real wages as its sole variable, their argument breaks down entirely and leaves the question of what the actual employment will be quite indeterminate. They do not seem to have realized that, unless the supply of labor is a function of real wages alone, their supply curve for labor will shift bodily with every movement of prices. Thus their method is tied up with their very special assumptions, and cannot be adapted to deal with the more general case. Now ordinary experience tells us, beyond doubt, that a situation where labor stipulates (within limits) for a money-wage rather than a real wage, so far from being a mere possibility, is the normal case. Whilst workers will usually resist a reduction of money- wages, it is not their practice to withdraw their labor whenever there is a rise in the price of wage-goods. It is sometimes said that it would be illogical for labor to resist a reduction of money-wages but not to resist a reduction of real wages. For reasons given below, this might not be so illogical as it appears at first; and, as we shall see later, fortunately so. But, whether logical or illogical, experience shows that this is how labor in fact behaves. Moreover, the contention that the unemployment which characterizes a depression is due to a refusal by labor to accept a reduction of money-wages is not clearly supported by the facts. It is not very plausible to assert that unemployment in the United States in 1932 was due either to labor obstinately refusing to accept a reduction of money-wages or to its obstinately demanding a real wage beyond what the productivity of the economic machine was capable of furnishing. Wide variations are experienced in the volume of employment without any apparent change either in the minimum real demands of labor or in its productivity. Labor is not more truculent in the depression than in the boom-far from it. Nor is its physical productivity less, These facts from experience are a prima facie ground for questioning the adequacy of the classical analysis.

单选题{{B}}Passage One{{/B}} The study of social science is more than the study of the individual social sciences. Although it is true that to be a good social scientist you must know each of those components, you must also know how they interrelate. By specializing too early, many social scientists can lose sight of the interrelationships that are so essential to understanding modern problems. That's why it is necessary to have a course covering all the social sciences. In fact, it would not surprise me if one day a news story such as the one above should appear. The preceding passage placed you in the future. To understand how and when social science broke up, you must go into the past. Imagine for a moment that you're a student in 1062, in the Italian city of Bologna, site of one of the first major universities in the western world. The university has no buildings. It consists merely of a few professors and students. There is no tuition fee. At the end of a professor's lecture, if you like it, you pay. And if you don't like it, the professor finds himself without students and without money. If we go back still earlier, say to Greece in the sixth century B. C., we can see the philosopher Socrates walking around the streets of Athens, arguing with his companions. He asks them questions, and then other questions, leading these people to reason the way he wants them to reason (this became known as the Socratic method). Times have changed since then; universities sprang up throughout the world and created colleges within the universities. Oxford, one of the first universities, now has thirty colleges associated with it, and the development and formalization of educational institutions has changed the roles of both students and faculty. As knowledge accumulated, it became more and more difficult for one person to learn, let alone retain it all. In the sixteenth century one could still aspire to know all there was to know, and the definition of the Renaissance man (people were even more sexist then than they are now) was of one who was expected to know about everything. Unfortunately, at least for someone who wants to know everything, the amount of information continues to grow {{U}}exponentially{{/U}} while the size of the brain has grown only slightly. The way to deal with the problem is not to try to know everything about everything. Today we must specialize. That is why social science separated from the natural sciences and why it, in turn, has been broken down into various subfields, such as anthropology and sociology.
