根据下列材料，请回答下列各题 Banking is about money; and no other familiar services or commodities arouse such excesses of passion anddislike. Nor is there any other about which more nonsense is talked. The type of thing that comes to mind is notwhat normally called economics, which is inexact rather than nonsensical, and only in the same way as all scientists are at the point where they try to predict people's behavior. and its consequences. Indeed most socialsciences and, for example, medicine could probably be described in the same way. However, it is common to hear assertions of the kind 'if you were marooned (孤立无援的． on a desertisland a few seed potatoes would be more useful to you than a million pounds' as though this proved somethingimportant about money except the undeniable fact that it would not be much used to anyone in a situation wherevery few of us are at all likely to find ourselves. Money in fact is a token, or symbolic object, exchangeable ondemand by its holders for goods and services. Its use for this purpose is universal except with in a small number ofprimitive agricultural communities. Money and the price mechanism, i.e., the changes in prices expressed in money terms of different goods andservices, are the means by which all modern societies regulate demand and supply for these things, Especiallyimportant are the relative changes in price of different goods and services compared with each other. To takerandom examples: the price of house building has over the past five years risen a good deal faster than that ofdomestic appliances like refrigerators, but slower than that of motor insurance or French Impressionist paintings.This fact has complex implications for students of the brick industry, trade unionism, town planning, insurancecompanies, fine art auctions, and politics. Unpacking these implications is what economics is about, but theirimplications for bankers are quite different. In general, in modern industrialized societies, prices of services or goods produced in a context requiring ahigh service-content (e.g., a meal in a restaurant． are likely to rise in price more rapidly than goods capable ofmass-production on a large scale. It is also a characteristic of highly developed economies that the number ofworkers employed in service industries tends to rise and that of workers employed in manufacturing to fall. Thediscomfort this truth causes the big general trade unions as they contrast their own situation with that of the rapidlygrowing white-collar unions has been an important source of tension in western political life for many years and islikely to remain so for many more. According to the author, banking __________A. is another form. of commoditiesB. arouses people's passionate concernC. is the same thing,as economyD. has the same description as medicine
