南开考博历年试题(微宏)

微观部分一、许多省区都把汽车工业作为本省的支柱产业,请用经济学原理分析,汽车工业的发展是否能促进我国经济的良性循环。
二、白领的月薪为几万元,而工人才几百元,请用经济学原理分析,现阶段我国收入差距过大的原因。
三、如果不考虑契约的风险性,“公司+农户”模式是否农民增收的有效途径。
四、证明利润一定时成本最小化问题和成本一定时利润最大化问题是对偶问题。
五、建立经济学模型,说明药品价格高是否因为中间环节太多。
“药品价格居高不下,最大的问题在于药品流通的中间环节太多,经过一、二、三级批发之后,药价就上去了。
药店之所以比医院便宜,关键在于减少了中间环节,消灭了中间商。
”中国制药工业近几年发展很快,生产力严重过剩,药品种类多而且替代性强,增加了医院的选择空间,哪一类药品加价空间大,医院就采购哪个品种,这是“规矩”,全国的医院没有例外。
没有办法强迫医院不要这样做而去改卖最便宜的药。
这是抬升药价的一个重要环节。
药品价格形成的关键性症结是因为流通环节过于庞杂,还有医院的垄断渠道。
医院是药业市场的需求终端,对于药品消费有着主宰权。
在中国药品消费总量中,医院占到80%,另外20%则从药店或其他渠道销售。
这种情形决定了医院在药品消费中扮演着一种不可替代的角色。
1.资源配置效率的含义是什么?X非效率的含义是什么?两者有何区别?2.逆向选择现象及其原因3.某产品市场有两家企业,每家企业的边际成本均为0,已经市场需求曲线为P(Y)=100-Y,其中Y=y1+y2, 竞争均衡下的总产出?企业为古诺竞争者,y2给定条件下,求企业1的最佳产量?每个古诺均衡下的产量?卡特尔下总产出?如果1是追随者,2是领导者,计算每个企业在斯塔格伯均衡下的产出?4.如果研究中国垄断和收入分配的关系,你将如何进行课题设计?5.阿罗不可能定理是用四个条件来规定的。
请对阿罗不可能定理作出定义,并解释这四个条件中每一个条件都是不可缺少的。
6.法国经济学家瓦尔拉斯(Walras)最早研究了竞争性市场体系的均衡问题并提出了瓦尔拉斯法则(Walras’Law),试证明瓦尔拉斯法则。

博士经济学面试题及答案

博士经济学面试题及答案1. 请简述经济学中的边际效用递减原理。
答案:边际效用递减原理是指随着消费者对某种商品或服务的消费量增加,其从每增加一个单位的消费中获得的额外满足感(即边际效用)逐渐减少的现象。
这一原理是消费者行为理论的基础之一,反映了消费者在不同商品和服务之间的选择和偏好。
2. 什么是市场失灵?请举例说明。
答案:市场失灵是指市场机制在某些情况下不能有效地分配资源,导致资源配置的效率低下。
例如,外部性问题(如污染)和公共品的提供(如国防、公共安全)是市场失灵的典型例子。
在这些情况下,市场无法通过价格机制来反映商品或服务的真实社会成本和效益。
3. 请解释完全竞争市场的条件。
答案:完全竞争市场的条件包括:市场上有大量买家和卖家,产品是同质的,市场信息完全透明,进入和退出市场没有障碍,以及没有政府干预。
在这种市场中,单个买家或卖家对价格没有影响力,价格由市场供求关系决定。
4. 什么是货币政策?请简述其主要工具。
答案:货币政策是中央银行用来影响经济活动,特别是总需求水平的一系列措施。
主要工具包括:调整利率(如联邦基金利率),公开市场操作(买卖政府债券以影响货币供应量),以及调整银行准备金率。
5. 请描述经济增长与发展的区别。
答案:经济增长通常指的是一个国家或地区的总产出(如GDP)随时间的增加。
而经济发展则更广泛,不仅包括经济增长,还包括生活质量的提高、社会福利的改善、技术进步和结构变化等方面。
6. 什么是机会成本?请举例说明。
答案:机会成本是指为了获得某项资源或进行某项活动而放弃的其他选择的最高价值。
例如,如果一个农民选择种植小麦而不是玉米,那么种植小麦的机会成本就是放弃种植玉米所能带来的收益。
7. 请解释什么是菲利普斯曲线。
答案:菲利普斯曲线描述了失业率与通货膨胀率之间的短期负相关关系。
在短期内,当失业率较低时,工资和价格上升的压力可能导致通货膨胀率增加;反之亦然。
然而,长期来看,这种关系可能会因为预期调整等因素而变得不那么明显。

Countless billions of ______ sea creatures and plants lived and sank to the sea bed.A. secondB. minuteC. hourD. dayPart Ⅲ Reading ComprehensionDirections:In this section, there are five passages. Read the passages and questions carefully and make your choices that you think would **plete the statements or best answer the questions by marking them on the ANSWER SHEET.Passage OneNo matter what you think about testing rends, one thing is clear: as long as there is teaching and learning, there will be testing. But how much credit do those charts and numbers deserve?When you review a school"s test scores at a school board meeting, always look beyond the basic numbers. The scores for a single school in a single year have limited value for judging school performance. Equally important is "trend data" —test scores from several years that show you how a school"s performance has changed over time. Additionally, comparing a school to otherschools with similar demographics may give your perspective on where the school stands relative to other schools like it. You can also learn a lot from data that is broken down by ethnic group and socioeconomic level. A school is only truly successful when it achieves high performance with students across all ethnic and social groups.On the other hand, the next time you hear somebody say, "That school is the best in the district because it has the highest test scores," make a point to respond: "I"d love to know more about what"s happening at the school that accounts for those scores, but I can"t assume that it"s the best school just based on one piece of evidence. What you know about the school"s teaching methods, the leadership of the principal, or its climate of safety?" Take time to investigate these other measures of school quality before making judgments about a school.To communicate with your child certainly is the final way. Raise your hand if you"ve heard some stories about students begging to stay home on test day. Is this level of anxiety appropriate? The correct answer is no! When your child"s class is preparing for its annual standardized testing marathon, let your child know that while you hope she does her best on the test, it"s not a competition. Explain that the results may help her and her teacher understand the areas where she might be especially strong or where she may need to focus more.1. The second paragraph implies that when you review a school"s test scores ______.A. you should give priority to the stores for this yearB. you should take into an account the performance of the students across all ethnic and social groupsC. you needn"t refer to the test scores in the past several yearsD. you don"t need to compare a school with others since you are only concerned about your children"s scores2. According to the author, when we evaluate the quality of a school, the following factors should be involved EXCEPT ______.A. teaching methodsB. leadership of the principalC. relationship with other schoolsD. safety3. In the last paragraph of this passage, the word "anxiety" in the sentence "Is this level of anxiety appropriate?" implies the child"s serious concern about ______.A. strict teachersB. competitive examC. unsafe conditions of the schoolD. no care from the parents4. What is the most proper title for this passage?A. Get Smart about School Test ScoresB. Don"t Look up to the Test ScoresC. The Scores Matter a LotD. Deal Better with the Child and ScoresPassage TwoThere are four basic types of competition in business that form a continuum from **petition through **petition and oligopoly (商品应垄断) to monopoly. At one end of the continuum, **petition results when **pany has a similar product. Companies that deal in commodities such as wheat or corn are often involved in **petition. In **petition, it is often the ease and efficiency of distribution that influences purchase.In contrast, in **petition **panies **pete for the sale of items that may be substituted. The classic example of **petition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts are often used as part of a marketing strategy to influence sales.Oligopoly occurs when a **panies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, **petition is not considered desirable because it would result in reduced revenue for **pany in the group. Although price wars do occur, in which **panies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously is also usual.Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these cases, it is government control, rather **petition, that protects and influences sales.1. Which of the following would be the best title for the passage?A. MonopoliesB. The Commodity MarketC. The Competition ContinuumD. The Best Type of Competition2. An example of a product in **petition is ______.A. cornB. electricityC. airline ticketsD. coffee3. What does the author mean by the statement "Although price wars do occur, in which **panies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously also usual"?A. It is not unusual for **panies to increase prices at the same timeB. It is common **panies to compete for customers by lowering pricesC. Customers may lose money **panies have price warsD. Prices are lower during price wars, but they are usually higher afterward4. The word "it" in Paragraph 3 refers to ______.A. a product or serviceB. competitionC. revenueD. oligopolyPassage ThreeIn August 2004, Duke University provided free iPods to its entire freshman class. The next month, a Korean education firm offered free downloadable college entrance exam lectures to students who purchased an iRiver personal multimedia player. That October, a financial trading firm in Chicago was reportedly assessing the hand-eye coordination of traders" using GameBoys. Yetwhile such innovative applications abound, the use of technology in education and training is far from new, a fact as true in language classrooms as it is in medical schools.Practically since their availability, a succession of audiovisual recording devices ( e. g. , reel-to- reel, VCRs, PCs) has been used to capture language samples, and myriad playback and broadcast devices (e. g. , phonographs, radios, televisions) have provided access to authentic speech samples. The espousal of audiolingual theory in the 1950s brought the widespread use of the language laboratory in educational settings. Influenced by behaviorism, the lab was progressively replaced in the 1960s by drill-**puter-assisted instruction, which decades later was itself surpassed by a more intelligent, interactive and **puter-assisted language learning. The popular acceptance of the Internet in the 1990s advanced the development of computer-**munications.As technologies continue to evolve, so does their propensity to shrink in size. "Other technologies that hold the capacity for language learning include PDAs, multimedia cellular phones, MP3 players, DVD players, and digital dictionaries. " Such portable media—referred to in popular and scholarly literature as mobile, wireless, handheld or nomadic—are now social staples. Mobile learning, or m-learning, is a burgeoning subdivision of the e-learning movement, further evidenced by European initiatives such as m-learning and Mobilearn. In this paper, applied fusions of m-learning and language learning follow, after which their benefits and challenges are reviewed.1. What is the article introduction specifically deals with?A. Language learningB. Emerging technologyC. Mobile assisted language learningD. Wired learning2.

Behaviorism language learning strategy does not include ______.A. pattern drillsB. learner autonomyC. rote memorizationD. repetitionPassage FourMost Americans believe that our society of consumption-happy, fun-loving, jet-traveling people creates the greats happiness for the greatest number. Contrary to this view, I believe that our present way of life leads to increasing anxiety, helplessness and, eventually, to the disintegration of our cultures. I refuse to identify fun with pleasure, consumption with joy, busyness with happiness, or the faceless, buck-passing "organization man" with an independent individual. Modem industrialism has succeeded in producing this kind of man. He is the "alienated" man. He is alienated in the sense that his actions, and his own forces have become estranged from him; theystand above him and against him, and rule him rather than being ruled by him. His life forces have been transformed into things and institutions, and these things and institutions have become idols. They are something apart from him, which he worships and to which he submits. Alienated man bows down before the works of his own hands. He experiences himself not as the active bearer of his own forces and riches but as an impoverished "thing", dependent on other things outside of himself. He is the prisoner of the very economic and political circumstances which he has created. Since our economic organizations is based on continuous and ever-increasing consumption (think of the threat to our economy if people did not buy a new car until their old one was really obsolete), contemporary industrial man is encouraged to be consumption-crazy. Without any real enjoyment, he "takes in" drink, food, cigarettes, sights, lectures, books, movies, television, any new kind of gadget. The world has become one great maternal breast, and man has become the eternal suckling, forever expectant, forever disappointed.In general, our society is becoming one of giant enterprises directed by a bureaucracy in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, fringe benefits, well-ventilated factories and piped music, and by psychologists and "human relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue—and white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.1. Modern industrialized society needs men who are ______.A. individualistic in their tastesB. capable of commanding the social machineC. obedient and submissiveD. free and independent2. An alienated man is one who is ______.A. in control of economic and political circumstancesB. ruled by the things he createsC. worshipped as an idolD. more interested in women than in sports cars3. Which of the following is NOT a characteristic of modern industrial society?A. Ever increasing consumptionB. BureaucracyC. Ever-increasing power of manD. Automated machines4. The word "prisoner" in the last sentence of Paragraph 2 closely means ______.A. the person who is detained by policeB. the person who is being put behind barC. the person who is confined to his circumstancesD. the person who is being kept away from the normal lifePassage FiveThere is a confusion about two distinct questions: (a) **puters made books obsolete? and (b)**puters make written and printed material obsolete?Let us suppose **puters will make books disappear (I do not think this will happen and I shall elaborate later on this point, but let us suppose so for the sake of the argument). Still, this would not entail the disappearance of printed material. We have seen that it was wishful thinking to hope **puters, and particularly word processors, would have helped to save trees. Computers encourage the production of printed material. We can imagine a culture in which there will be no books, and yet where people go around with tons and tons of unbound sheets of paper. This will be quite unwieldy, and will pose a new problem for libraries.Debray has observed that the fact that Hebrew civilization was a civilization based upon a book is not independent of the fact that it was a nomadic civilization. I think that this remark is very important. Egyptians could carve their records on stone obelisks, Moses could not. If you want to cross the Red Sea, a book is a more practical instrument for recording wisdom. By the way, another nomadic civilization, the Arabic one, was based upon a book, and privileged writing upon images.But books also have an advantage with respect to computers. Even if printed on acid paper, which lasts only seventy years or so, they are more durable than magnetic supports. Moreover, they do not suffer power shortages and blackouts, and are more resistant to shocks. As Bolter remarked, "it is unwise to try to predict technological change more than few years in advance," but it is certain that, up to now at least, books still represent the most economical, flexible, wash-and-wear way to transport information at a very low cost.**munication travels ahead of you, books, travel with you and at your speed, but if you are shipwrecked on a desert island, a book can be useful, while a computer cannot—as Landow remarks, electronic texts need a reading station and a decoding device. Books are still the **panions for a shipwreck, or for the Day After.I am pretty sure that new technologies will render obsolete many kinds of books, like encyclopedias and manuals. Take for example the Encyclomedia project developed by Horizons Unlimited. When finished it will probably contain more information than the Encyclopedia Britannica (or Treccani or Larousse), with the advantage that it permits cross-references and nonlinear retrieval of information. The whole of **pact disks, plus **puter, will occupy one-fifth of the space occupied by an encyclopedia. The encyclopedia cannot be transported as the CD-ROM can, and cannot be easily updated; it does not have the practical advantages of a normal book, therefore it can be replaced by a CD-ROM, just a phone book can. The shelves today occupied, at my home as well as in public libraries, by meters and meters of encyclopedia volumes could be eliminated in the next age, and there will be no reason to lament their disappearance. For the same reason today I no longer need a heavy portrait painted by an indifferent artist, for I can send my sweetheart a glossy and faithful photograph. Such a change in the social functions of painting has not made painting obsolete, not even the realistic paintings of Annigoni, which do not fulfill the function of portraying a person, but of celebrating an important person, so that **missioning, the purchasing, and the exhibition of such portraits acquire aristocratic connotations.Books will remain indispensable not only for literature, but for any circumstance in which one needs to read carefully, not only to receive information but also to speculate and to reflect about it. To read a computer screen is not the same as to read a book. Think of the process of learning how to use a piece of software. Usually the system is able to display on the screen all the instructionsyou need. But the users who want to learn the program generally either print the instructions and read them as if they were in book form, or they buy a printed manual (let me skip over the fact that currently all the manuals **e with a computer, on-line or off-line, are obviously written by irresponsible and tautological idiots, **mercial handbooks are written by intelligent people). It is possible to conceive of a visual program that explains very well how to print and bind a book, but in order to get instructions on how to write such a computer program, we need a printed manual. After having spent no more than twelve hours at a computer console, my eyes are like two tennis balls, and I feel the need to **fortably down in an armchair and read a newspaper, or maybe a good poem. It seems to me **puters are diffusing a new form of literacy but are incapable of satisfying all the intellectual needs they are stimulating. In my periods of optimism I dream of a computer generation which, compelled to read a computer screen, gets acquainted with reading from a screen, but at a certain moment feels unsatisfied and looks for a different, more relaxed, and **mitting form of reading.1. "Hebrew civilization was a civilization based upon a book" indicates that printed books will be ______.A. preserved permanentlyB. perused widelyC. repaired when damagedD. transcribed as heritage2. The advantages of the printed books include all of the following except ______.A. being less durable than magnetic supportsB. not suffering power shortages and blackoutsC. being more resistant to shocksD. transporting information at a very low cost3. The example of Encyclomedia project developed by Horizons Unlimited shows that ______.A. CD-ROM can store more informationB. the space is left on shelvesC. the e-encyclopedia is more superiorD. the disappearance of normal print is a grief4. By comparison, the author likes to do reading ______.A. onlineB. off lineC. at leisureD. during the adventurePart Ⅳ ClozeDirections:Read the article below and fill in each of the blanks with one suitable word or phrase by marking your choices on the ANSWER SHEET.The marvel of the machine age, the **puter has been 1 only since 1946.

Read/he passages and questions carefully and make your choices that you think would best complete the statements or best answer the questions by marking them on the ANSWER SHEET.Passage 1.No matter what you think about testing rends, one thing is clear: as long as there is teaching and learning, there will be testing. But how much credit do those charts and numbers deserve?When you review a school's test scores at a school board meeting, always look beyond the basic numbers. The scores for a single school in a single year have limited value for judging school performance. Equally important is “trend data”一test scores from several years that show you how a school's performance has changed over time. Additionally, comparing a school to other schools with similar demographics may give your perspective on where the school stands relative to other schools like it. You can also learn a lot from data that is broken down by ethnic group and socioeconomic level. A school is only truly successful when it achieves high performance with students across all ethnic and social groups.On the other hand, the next time you hear somebody say.” T hat school is the best in the district because it has the highest test scores,” make a point to respond: “I’d love to know moreIabout what’s happening at the school that accounts for those scores, but I can’t assume that it’s the best school just based on one piece of evidence. What you know about the school's teaching methods, the leadership of the principal, or its climate of safety?” Take time to investigate these other measures of school quality before making judgments about a school. To communicate with your child certainly is the final way. Raise your hand if you've heard some stories about students begging to stay home on test day. Is this level of anxiety appropriate? The correct answer is no! When your child’s class is preparing for its annual standardized testing marathon, let your child know that while you hope she does her best on the test, it's not a competition. Explain that the results may help her and her teacher understand the areas where she might be especially strong or where she may need to focus more.36 The second paragraph implies that when you review a school's test scores. .A. you should give priority to the stores for this yearB. you should take into an account the performance of the students across all ethnic and social groupsC. you needn't refer to the test scores in the past several yearsD. you don ’t need to compare a school with others since you are only concerned about your children's scores37 According to the author, when we evaluate the quality of a school, the fo llowing factors should be involved EXCEPT .A. teaching methodsB. leadership of the principalC. relationship with other schoolsD. safely38 In the last paragraph of this passage, the word “anxiety” in the sentence “I s this level of anxiety appropriate?” implies the child's serious concern about.A. strict teachersB. competitive examC. unsafe conditions of the schoolD. no care from the parents 39 What is the most proper title for this passage ?A. Get Smart about School Test ScoresB. Don't Look up lo the Test ScoresC. The Scores Matter a LotD. Deal Better with the Child and ScoresPassage TwoThere are four basic types of competition in business that form. a continuum from pure competition through monopolistic competition and oligopoly (商品供应垄断) to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase.In contrast, in monopolistic competition several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts are often used as part of a marketing strategy to influence sales.Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously is also usual.Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these cases, it is government control, rather than competition, that protects and influences sales.40 Which of the following would be the best title for the passage?A. Monopolies:B. The Commodity MarketC. The Competition ContinuumD. The Best Type of Competition41 An example of a product in monopolistic competition is .A. cornB. electricityC. airline ticketsD. coffee42 What does the author mean by the statement "Although price wars do occur, in which all companies offer substantial savings to customers, a somewhat similar tendency to raise prices simultaneously also usual"?A. It is not unusual for all companies to increase prices at the same time.IB. It is common for companies to compete for customers by lowering prices.C. Customers may lose money when companies have price wars.D. Prices are lower during price wars, but they are usually higher afterward.43 The word "it" in paragraph 3 refers toA. a product or serviceB. competitionC. revenueD. oligopolyPassage ThreeIn August 2004, Duke University provided free iPods to its entire freshman class. The next month, a Korean education firm offered free downloadable college entrance exam lectures to students who purchased an iRiver personal multimedia player. That October, a financial trading firm in Chicago was reportedly assessing the hand-eye coordination of traders’ using GameBoys. Yet while such innovative applications abound, the use of technology in education and training is far from new, a fact as true in language classrooms as it is in medical schools.Practically since their availability, a succession of audiovisual recording devices (e.g., reel-to-reel, VCRs, PCs) has been used to capture language samples, and myriad playback and broadcast devices (e.g., phonographs, radios, televisions) have provided access to authentic speech samples. The espousal of audiolingual theory in the 1950s brought the widespread use of the language laboratory in educational settings. Influenced by behaviorism, the lab was progressively replaced in the 1960s by drill-based computer-assisted instruction, which decades later was itself surpassed by a more intelligent, interactive and multimedia computer-assisted language learning. The popular acceptance of the Internet in the 1990s advanced the development of computer-mediated communications.As technologies continue to evolve, so does their propensity to shrink in size. "Other technologies that hold the capacity for language learning include PDAs, multimedia cellular phones, MP3 players, DVD players, and digital dictionaries". Such portable media —referred to in popular and scholarly literature as mobile, wireless, handheld or nomadic —are now social staples. Mobile learning, or m-learning, is a burgeoning subdivision of the e-learning movement, further evidenced by European initiatives such as m-learning and Mobilearn. In this paper, applied fusions of m-learning and language learning follow, after which their benefits and challenges are reviewed.44 What is the article introduction specifically deals with?A. language learningB. Emerging technologyC. Mobile assisted language learningD. Wired learning45 The word " espousal ",in paragraph two can be best replaced byA. advocateB. supportC. ideaD. perception46 Mobile learning is a burgeoning subdivision of the e-learning movement in the sense that you can study withoutA. iPhoneB. laptopC. PDAD. desktop computer47 Behaviorism language learning strategy does not include:,A. pattern drillsB. learner autonomyC. rote memorizationD. repetitionPassage FourMost Americans believe that our society of consumption-happy, fun-loving, jet-traveling people creates the greats happiness for the greatest number.

It is possible to conceive of a visual program that explains very well how to print and bind a book, but in order to get instructions on how to write such a computer program, we need a printed manual.After having spent no more than twelve hours at a computer console, my eyes are like two tennis balls, and I feel the need to sit comfortably down in an armchair and read a newspaper, or maybe a good poem. It seems to me that computers are/diffusing a new form of literacy but are incapable of satisfying all the intellectual needs they are stimulating. In my periods of optimism I dream of a computer generation which, compelled to read a computer screen, gets acquainted with reading from a screen, but at a certain moment feels unsatisfied and looks for a different, more relaxed, and differently-committing form of reading.52 “Hebrew civilization was a civili zat ion based upon a book” indicates that printed books will beA. preserved permanentlyB. perused widelyC. repaired when damagedD. transcribed as heritage.53 The advantages of the printed books include all of the following exceptA. being less durable than magnetic supports.B. not suffering power shortages and blackoutsC. being more resistant to shocksD. transporting information at a very low cost.54 The example of Encyclomedia project developed by Horizons Unlimited shows thatA.
