D.How to convert absolute scarcity ofre sources into relative one Questions 31to 35are based on the following passage In 1665,Hooke published a book,in which he said that light travels in small,rapid vibrations,and that colored light is produced by changes in these vibrations.Hooke had developed a number of experiments with light and color,and his theory grew out of these experiments. Seven years later, a new member of the Royal Society,Is ac Newton,sent to the Society an account of one of his experiences.Newton had been making enses in an attempt to makea refracting (telescope.But no matter how carefully he worked,a weak ring of colors always blacked out the outer part of each lens.This color ring interested him,and he decided that he would have to know more about light and color before he could go on with his instrument resources；it means the foregoing of an opportunity to produce something else．In deciding how to use resources most effectively to satisfy the wants of the community，this opportunity cost must be taken into account． In a market economy the price of a goods and the quantity supplied depends on the cost of making it，and the cost，ultimately，is the cost of not making other goods．The market mechanism enforces this relationship．The cost of， say，a pair of shoes is the price of the leather，the labor， the fuel，and other elements used up in producing them．But the price of these in- puts，in turn， depends on what they can produce elsewhere，if the leather can be used to produce handbags that are valued highly by consumers， the price of leather will be bid up correspondingly． 26．According to the passage，what are the opportunity costs of an item？ A．The price of the material，labor and other elements consumed in manufacturing it． B．The amount of time and energy spent in producing it． C．The value of all the resources used in its production． D．The value of what could have been produced instead． 27．What is the relationship between production and resources？ A．Production reduces the amount of available resources． B．Production has nothing to do with resources． C．Production increases as resources increase． D．Production is stimulated by resources available． 28．What determines the price of goods in a market economy？ A．The cost of all elements involved in production． B．The quantity of materials supplied． C．The efficiency of the manufacturing process． D．The cost of labor． 29．Which of the following statements is TRUE according to the passage？ A．The cost of a product reflects its usefulness in society． B．The cost of a product depends on its quality． C．The price of a product reflects its usefulness in society． D．The price of a product reflects its opportunity costs． 30．What are economists concerned about with regard to resources？ A．How to tap natural resources． B．How to cope with absolute scarcity of resources． C．How to use available resources appropriately． D．How to convert absolute scarcity of resources into relative one． Questions 31to 35are based on the following passage： In 1665，Hooke published a book，in which he said that light travels in small，rapid vibrations，and that colored light is produced by changes in these vibrations．Hooke had developed a number of experiments with light and color，and his theory grew out of these experiments． Seven years later，a new member of the Royal Society，Issac Newton，sent to the Society an account of one of his experiences．Newton had been making lenses in an attempt to make a refracting（折射的）telescope．But no matter how carefully he worked，a weak ring of colors always blacked out the outer part of each lens．This color ring interested him，and he decided that he would have to know more about light and color before he could go on with his instrument
