gmat数学真题及解析答案详解

gmat数学真题及解析答案详解GMAT数学真题及解析答案详解GMAT（全球管理硕士研究生入学考试）是一个非常重要的考试，它对于想要进入顶尖商学院深造的学生来说至关重要。

GMAT考试包括四个部分，其中数学部分是很多考生担心的一部分。

本文将介绍一些GMAT数学真题，并给出详细的解析答案，帮助考生更好地准备考试。

题目一：The cost, in dollars, of producing x units of a certain commodity is given by the equation C = mx + b, where m and b are constants. If the cost of producing 50 units is $1800 and the cost of producing 100 units is $2800, what is the cost of producing 150 units?解析：首先，根据题目中的信息，我们可以得到两个方程：1800 = m(50) + b2800 = m(100) + b我们需要求解的是当x=150时的C的值。

为了求解这个问题，我们需要求解m和b的值。

我们可以使用第一个方程来求解m和b的值：1800 = m(50) + b2800 = m(100) + b我们可以通过减去两个方程得到：1000 = m(50)因此，m的值为20。

将m的值带入第一个方程，我们可以求解b 的值：1800 = 20(50) + bb = 1800 - 1000b = 800现在，我们可以使用C = mx + b的方程来计算当x=150时的C的值：C = 20(150) + 800C = 3000 + 800C = 3800因此，当生产150个单位时的成本为3800美元。

题目二：The average (arithmetic mean) of 7 numbers is 10. If one of the numbers is removed, and the average of the remainingnumbers is 9, what is the value of the number that was removed?解析：让我们假设被移除的数字为x。

GMAT考试2024量化历年真题全视角

GMAT考试2024量化历年真题全视角GMAT考试（Graduate Management Admission Test）是一项全球性的管理类研究生入学考试。

它的量化部分是考察考生在数学和逻辑推理能力方面的表现，是备战GMAT考试中非常重要的一部分。

在准备GMAT考试的过程中，历年真题是必不可少的参考资源，它们能够帮助考生了解考试的题型、难度和命题风格，从而更好地进行备考。

本文将从全视角介绍GMAT考试2024年的量化部分历年真题，并提供相关题目的解析和解题技巧。

一、Data Sufficiency（数据充分性）题目Data Sufficiency题目是GMAT考试量化部分中的一大特色。

这类题目要求考生判断所给的数据是否足够解决问题。

以下是GMAT考试2024年的一个Data Sufficiency题目：题目：Is the integer x divisible by 3?1. x is divisible by 6.2. The sum of the digits of x is divisible by3.解析：这道题目要求判断整数x是否可以被3整除。

我们先来看一下两个陈述句的意义。

第一条陈述句表明x可以被6整除，我们知道6是3的倍数，所以第一条陈述句意味着x也可以被3整除。

第二条陈述句表明x的各位数字之和可被3整除，这说明x本身可以被3整除。

综上所述，无论是第一条陈述句还是第二条陈述句，都能够得出x 可以被3整除的结论。

因此，答案是D，两个陈述句均充分。

二、Problem Solving（问题求解）题目Problem Solving题目是GMAT考试中的另一类常见题型。

以下是GMAT考试2024年的一个Problem Solving题目：题目：If a, b, and c are positive integers, what is the value of (a + b) / c?(1) a = 3c(2) b = 2c解析：这道题目要求求解表达式(a + b) / c的值。

让知识带有温度。

2022年7月GMAT写作真题（一）720AA1：“In the first four years that Montoya has served as mayor of the city of San Perdito, the population has decreased and the unemployment rate has increased. Two businesses have closed for each new business that has opened. Under Varro, who served as mayor for four years before Montoya, the unemployment rate decreased and the population increased. Clearly, the residents of San Perdito would be best served if they voted Montoya out of office and reelected Varro.AA2：果农Over the past decade, the price per pound of citrus fruit has increased substantially. Eleven years ago, Megamart charged 5 cents apiece for lemons, but today it commonly charges over 30 cents apiece. In only one of these last eleven years was the weather unfavorable for growing citrus crops. Evidently, then, citrus growers have been responsible for the excessive increase in the price of citrus fruit, and strict pricing regulations are needed to prevent them from continuing to inflate prices.”AA3：“Research indicates that those who exercise regularly are hospitalized less than half as often as those whodon’t exercise. By providing a wellequipped gym for Saluda’s municipal employees, we should be able toreduce the cost of our group health insurance coverage by approximately 50% and thereby achieve a balanced town budget.”AA4：“Muscle Monthly, a fitness magazine that regularly features pictures of bodybuilders using state-of-the-art exercise machines, frequently sells out, according to the owner of Skyview Newsstand. To help maximize fitness levels in our town’s residents, we should, therefore, equip our new community fitness center with such machines.”第1页/共3页千里之行，始于足下AA5：一个人在一个叫SALLON的TOWN里有个小餐馆,买辣汉堡.两年前生意很好由于旁边有个LARGE PUBLIC SCHOOL 现在他预备去开3个新的店. 请始终跟他的3个人做MANAGERS 说自己的收入会是3倍AA6：Eight years ago, our firm’s profits were increasing with each new employee we added. We discovered that eachemployee had the skills and motivation to generate more revenue for the firm than his or her salary cost us.However, for the past two years, our profit margin has been falling, even though we have continued to addemployees. Thus, our newer employees are not generating enough revenue to justify their salaries. We mustnot be hiring new employees with the same level of skills and motivation as those we used to attract. Clearly,then, failures in the human resources department account for our falling profits.”AA7：The following appeared as part of a memorandum from the loan department of the Frostbite National Bank.“We should not approve the business loan application of the local group that wants to open a franchise outlet for the Kool Kone chain of ice cream parlors. Frostbite is known for its cold winters, and cold weather can mean slow ice cream sales. For example, even though Frostbite is a town of 10,000 people, it has only one ice cream spot — the Frigid Cow. Despite the lack of competition, the Frigid Cow’s net revenues fell by 10 percent last winter.”AA8：一个company的Cookville分厂很advanced and efficiency, since它的单位时间产量较其他分厂要高。

2023年GMAT考试真题

2023年GMAT考试真题第一部分：数学问题1：某公司2022年销售额为X万元，比上一年增长了25%，请计算2021年该公司的销售额。

解答1：设2021年销售额为Y万元。

根据题意有：X = Y +0.25Y。

化简得到：X = 1.25Y。

解方程可得：Y = X / 1.25。

问题2：已知正方形ABCD的边长为4cm，线段EF平分了BC，且垂直于BC。

求EF的长度。

解答2：由于EF与BC垂直，故BF=FC。

又因为BD=DC=4/2=2cm，所以三角形BDE为等腰直角三角形。

根据勾股定理可得：DE = sqrt(2^2 + (4/2)^2) = sqrt(4 + 4) = sqrt(8) =2sqrt(2) cm。

因此，EF的长度为2DE = 2*2sqrt(2) = 4sqrt(2) cm。

问题3：若a = 3^2^2，b = 2^3^4，c = (ab)^(1/2)，求c的值。

解答3：首先计算a的值：a = 3^2^2 = 3^4 = 81。

然后计算b的值：b = 2^3^4 = 2^81。

由于指数运算满足指数法则，即a^b^c =a^(b*c)，所以b = 2^(3*4) = 2^12。

将a和b的值代入c的表达式可得：c = (81*2^12)^(1/2) = (81*2^12)^(1/2) = sqrt(81*2^12)。

化简得：c = 9*2^6 = 576。

第二部分：语言问题1：选择最佳替代词以完善以下句子：“He is a ______artist and has won numerous awards.”a) talentedb) stubbornc) cautiousd) curious解答1：a) talented。

问题2：填入正确的介词以完善以下句子：“I'm looking forward ______ the weekend.”a) tob) inc) atd) for解答2：a) to。

37. Editorialist: Drivers with a large number of demerit points who additionally have been convicted of a serious driving-relative offense should either be sentenced to jail or be forced to receive driver reeducation, since to do otherwise would be to allow a crime to go unpunished. Only if such drivers are likely to be made more responsible drivers should driver re-education be recommended for them. Unfortunately, it is always almost impossible to make drivers with a large number of demerit points more responsible drivers. If the editorialist's statements are true, they provide the most support for which one of the following? (A) Drivers with a large number of demerit points who have been convicted of a serious driving-related offense should be sent to jail. (B) Driver re-education offers the best chance of making drivers with a large number of demerit points responsible drivers. (C) Driver re-education is not a harsh enough punishment for anyone convicted of a serious driving-related offense who has also (D) Driver re-education should not be recommended for those who have committed no serious (E) Drivers with a larger number of demerit points but no conviction for a serious driving-related offense should receive driver re-education rather than jail 38. Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth's ozone layer has been continuously depleted throughout the last 50 years. Atmospheric ozone blocks UV-B, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer. Each of the following, if true, would strengthen the argument EXCEPT: (A) Of the various types of radiation blocked by atmospheric ozone, UV-B is the only type that can damage genes. (B) Amphibian populations are declining far more rapidly than are the populations of nonamphibian species whose tissues and eggs have more natural protection from UV-B. (C) Atmospheric ozone has been significantly depleted above all the areas of the world in which amphibian populations are declining. (D) The natural habitat of amphibians has not become smaller over the past century. (E) Amphibian populations have declined continuously for the last 50 years. 39. Quasars——celestial objects so far away that their light takes at least 500 million years to reach Earth——have been seen since 1963. For anything that far away to appear from Earth the way quasars do, it would have to burn steadily at a rate that produces more light than 90 billion suns would produce. But nothing that burns at a rate that produces that much light could exist for more than about 100 million years. If the statements above are true, which one of the following must also be true on the basis of them? (A) Instruments in use before 1963 were not sensitive enough to permit quasars to be seen. (B) Light from quasars first began reaching Earth in 1963. (C) Anything that from Earth appears as bright as a quasar does must produce more light than would be produced by 90 billion suns. (D) Nothing that is as far from Earth as quasars are can continue to exist for more than about 100 million years. (E) No quasar that has ever been seen from Earth exists any longer. 40. More and more computer programs that provide solutions to mathematical problems in engineering are being produced, and it is thus increasingly unnecessary for practicing engineers to have thorough understanding of fundamental mathematical principles. Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles, so that space in the engineering curriculum will be available for other important subjects. Which one of the following, if true, most seriously weakens the argument given for the recommendation above? (A) The effective use of computer program that provide solutions to mathematical problems in engineering requires an understanding of mathematical principles. (B) Many of the computer programs that provide solutions to mathematical problems in engineering are already in routine use. (C) Development of composites and other such new materials has meant that the curriculum for engineers who will work in industry must allow time for teaching the properties of these materials. (D) Most of the computer programs that provide solutions to mathematical problems in engineering can be run on the types of computers available to most engineering firms. (E) The engineering curriculum already requires that engineering students be familiar with and able to use avariety of computer programs. 41. Raymond Burr played the role of lawyer Perry Mason on television. Burr's death in 1993 prompted a prominent lawyer to say "Although not a lawyer, Mr. Burr strove for such authenticity that we feel as if we lost one of our own." This comment from a prestigious attorney provides appalling evidence that, in the face of television, even some legal professionals are losing their ability to distinguish fiction from reality. The reasoning in the argument is flawed because the argument (A) takes the views of one lawyer to represent the views of all lawyers (B) criticizes the lawyer rather than the lawyer's statement (C) presumes that the lawyer is qualified to evaluate the perFORMance of an actor (D) focuses on a famous actor's portrayal of a lawyer rather than on the usual way in which lawyers are portrayed on television (E) ignores the part of the lawyer's remark that indicates an awareness of the difference between reality and fiction 42. For next year, the Chef's Union has requested a 10 percent salary increase for each of its members, whereas the Hotel Managers' Union has requested only an 8 percent salary increase for each of its members. These facts demonstrate that the average dollar amount of the raises that the Chefs' Union has requested for next year is greater than that of the raises requested by the Hotel Managers' Union. Which one of the following, if true, most strengthens the argument? (A) The Chefs' Union has many more members than does the Hotel Managers' Union. (B) The Chefs' Union is a more powerful union than is the Hotel Managers' Union and is therefore more likely to obtain the salary increases it requests (C) The current salaries of the members of the Chefs' Union are, on average, higher than the current salaries of the members of the Hotel Managers' Union (D) The average dollar amount of the raises that the members of the Chefs' Union received last ear was equal to the average dollar amount of the raises that the members of the Hotel Managers' Union received (E) The members of the Chefs' Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers' Union received salary increases of only 8 percent in each of the last two years 43. Zoos have served both as educational resources and as entertainment. Unfortunately, removing animals from their natural habitats to stock the earliest zoos reduced certain species' populations, endangering their survival. Today most new zoo animals are obtained from captive breeding programs, and many zoos now maintain breeding stocks for continued propagation of various species. This makes possible efforts to reestablish endangered species in the wild. Which one of the following statements is most strongly supported by the inFORMation above? (A) Zoos have played an essential role in educating the public about endangered species. (B) Some specimens of endangered species are born and bred in zoos. (C) No zoos exploit wild animals or endanger the survival of species. (D) Nearly all of the animals in zoos today were born in captivity. (E) The main purpose of zoos has shifted from entertainment to education. 44. Legal theorist: It is unreasonable to incarcerate anyone for any other reason than that he or she is a serious threat to the property or lives of other people. The breaking of a law does not justify incarceration, for lawbreaking proceeds either from ignorance of the law or of the effects of one's actions, or from the free choice of the lawbreaker. Obviously mere ignorance cannot justify incarcerating a lawbreaker, and even free choice on the part of the lawbreaker fails to justify incarceration, for free choice proceeds from the desires of an agent, and the desires of an agent are products of genetics and environmental conditioning, neither of which is controlled by the agent The claim in the first sentence of the passage plays which one of the following roles in the argument (A) It is offered as a premise that helps to show that no actions are under the control of the agent (B) It is offered as background inFORMation necessary to understand the argument (C) It is offered as the main conclusion that the argument is designed to establish (D) It is offered as evidence for the stated claim that protection of life and property is more important than retribution for past illegal acts (E) It is offered as evidence for the stated claim that lawbreaking proceeds from either ignorance of the law, or ignorance of the effects of one's actions, or free choice 45. Commissioner: Budget forecasters project a revenue shortfall of a billion dollars in the coming fiscal year. Since there is no feasible way to increase the available funds, our only choice is to decrease expenditures. The plan before you outlines feasible cuts that would yield savings of a billion dollars over the coming fiscal year. We will be able to solve the problem we face, therefore, only if we adopt this plan. This reasoning in the commissioner's argument is flawed because this argument (A) relies on inFORMation that is far from certain (B) confuses being an adequate solution with being a required solution (C) inappropriately relies on the opinions of experts (D) inappropriately employs language that is vague (E) takes for gran t e d t h a t t h e r e i s n o w a y t o i n c r e a s e a v a i l a b l e f u n d s / p > p b d s f i d = " 1 2 9 " > / p > / d i v > d i v i d = " f l o a t _ b t n " c l a s s = " " b d s f i d = " 1 3 0 " > b u t t o n c l a s s = " f l o a t _ b t n l e f t _ b t n " i d = " c o p y _ b u t t o n " d a t a - c l i p b o a r d - a c t i o n = " c o p y " d a t a - c l i p b o a r d - t a r g e t = " # c o n t e n t - t x t " o n c l i c k = " d o _ c o p y ( ) ; " b d s f i d = " 1 3 1 " > e m c l a s s = " i c o n " b d s f i d = " 1 3 2 " >。

otters in the North Pacific Ocean began to decline.Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely.After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably.Which of the following, if true, most seriously weakens the reasoning?A.Killer whales in the North Pacific usually prey on seals and sea lions but will,when this food source is scarce, seek out other prey.B.There is no indication that substantial numbers of sea otters migrated to otherlocations from the North Pacific in the 1980’s.C.Along the Pacific coast of North America in the 1980’s, sea otters were absentfrom many locations where they had been relatively common in former times.D.Following the decline in the population of the sea otters, there was an increase inthe population of sea urchins, which are sea otters’ main food source.E.The North Pacific populations of seals and sea lions cover a wider geographicarea than does the population of sea otters.Answer:------------------------------------------------------------------------------------------------------------Q4 to Q6:Frazier and Mosteller assert thatmedical research could be improved bya move toward larger, simpler clinicalLine trials of medical treatments.Currently,(5) researchers collect far more backgroundinformation on patients than is strictlyrequired for their trials—substantially morethan hospitals collect—thereby escalatingcosts of data collection, storage, and(10) analysis.Although limiting informationcollection could increase the risk thatresearchers will overlook facts relevantto a study, Frazier and Mosteller contendthat such risk, never entirely eliminable(15) from research, would still be small in moststudies.Only in research on entirely newtreatments are new and unexpected vari-ables likely to arise.Frazier and Mosteller propose not(20) only that researchers limit data collec-tion on individual patients but also thatresearchers enroll more patients in clinical4(25) (30) (35) (40) trials, thereby obtaining a more represen- tative sample of the total population with the disease under study.Often research- ers restrict study participation to patients who have no ailments besides those being studied.A treatment judged successful under these ideal conditions can thenbe evaluated under normal conditions. Broadening the range of trial participants, Frazier and Mosteller suggest, would enable researchers to evaluate a treat- ment’s efficacy for diverse patients under various conditions and to evaluate its effectiveness for different patient sub- groups.For example, the value of a treatment for a progressive disease may vary according to a p atient’s stage of disease.Patients’ ages may also affecta treatment’s efficacy.--------------------------------------------------------------------------------Q4:According to the passage, Frazier and Mosteller believe which of the following about medical research?A.It is seriously flawed as presently conducted because researchers overlook factsthat are relevant to the subject of their research.B.It tends to benefit certain subgroups of patients disproportionately.C.It routinely reveals new variables in research on entirely new treatments.D.It can be made more accurate by limiting the amount of information researcherscollect.E.It cannot be freed of the risk that significant variables may be overlooked.Answer:--------------------------------------------------------------------------------Q5:The author mentions patients’ ages (line 40) primarily in order toA.identify the most critical variable differentiating subgroups of patientsB.cast doubt on the advisability of implementing Frazier and Mosteller’s proposalsabout medical researchC.indicate why progressive diseases may require different treatments at differentstagesD.illustrate a point about the value of enrolling a wide range of patients in clinicaltrialsE.substantiate an argument about the problems inherent in enrolling large numbersof patients in clinical trialsAnswer:5--------------------------------------------------------------------------------Q6:The passage is primarily concerned withA.identifying two practices in medical research that may affect the accuracy ofclinical trialsB.describing aspects of medical research that tend to drive up costsC.evaluating an analysis of certain shortcomings of current medical researchpracticesD.describing proposed changes to the ways in which clinical trials are conductedE.explaining how medical researchers have traditionally conducted clinical trialsand how such trials are likely to changeAnswer:------------------------------------------------------------------------------------------------------------ Q7 to Q10:The system of patent-granting, which conferstemporary monopolies forLine the exploitation of new tech-(5) nologies, was originallyestablished as an incentiveto the pursuit of risky newideas.Yet studies of themost patent-conscious(10) business of all—the semi-conductor industry—suggestthat firms do not necessarilybecome more innovative asthey increase their patenting(15) activity.Ziedonis and Hall,for example, found thatinvestment in research anddevelopment (a reasonableproxy for innovation) did(20) not substantially increasebetween 1982 and 1992,the industry’s most feverishperiod of patenting.Instead,semiconductor firms simply(25) squeezed more patents outof existing research anddevelopment expenditures.Moreover, Ziedonis andHall found that as patenting(30) activity at semiconductorfirms increased in the6(35) (40) (45) (50) (55) 1980’s, th e consensus among industry employees was that the average quality of their firms’ patents declined.Though patent quality is a difficult notion to measure, the number of times a patent is cited inthe technical literature isa reasonable yardstick, and citations per semiconductor patent did decline during the 1980’s.This decline in quality may be related to changes in the way semi- conductor firms managed their patenting process: rather than patenting to win exclusive rig hts to a valuable new technology, patents were filed more for strategic purposes, to be used as bargaining chips to wardoff infringement suites oras a means to block competitors’ products.--------------------------------------------------------------------------------Q7:The passage is primarily concerned with discussingA. a study suggesting that the semiconductor industry’s approach to patenting duringthe period from 1982 to 1992 yielded unanticipated resultsB. a study of the semiconductor industry during the period from 1982 to 1992 thatadvocates certain changes in the industry’s management of the patenting processC.the connection between patenting and innovation in the semiconductor industryduring the period from 1982 to 1992D.reasons that investment in research and development in the semiconductorindustry did not increase significantly during the period from 1982 to 1992E.certain factors that made the period from 1982 to 1992 a time of intense patentingactivity in the semiconductor industryAnswer:--------------------------------------------------------------------------------Q8:The passage suggests which of the following about patenting in the semiconductor industry during the period from 1982 to 1992 ?7A.The declining number of citations per semiconductor patent in the technicalliterature undermines the notion that patenting activity increased during thisperiod.B. A decline in patent quality forced firms to change the way they managed thepatenting process.C.Increased efficiencies allowed firms to derive more patents from existingresearchand development expenditures.D.Firms’ emphasis on filing patents for strategic purposes may have contributed to adecline in patent quality.E.Firms’ attempts to derive more patents from existing research and developmentexpenditures may have contributed to a decline in infringement suites.Answer:--------------------------------------------------------------------------------Q9:The passage makes which of the following claims about patent quality in the semiconductor industry?A.It was higher in the early 1980’s than it was a decade later.B.It is largely independent of the number of patents granted.C.It changed between 1982 and 1992 in ways that were linked to changes inresearch and development expenditures.D.It is not adequately discussed in the industry’s t echnical literature.E.It was measured by inappropriate means during the period from 1982 to 1992.Answer:--------------------------------------------------------------------------------Q10:Which of the following, if true, would most clearly serve to weaken the author’s claim about what constitutes a reasonable yardstick for measuring patent quality?A.It is more difficult to have an article accepted for publication in the technicalliterature of the semiconductor industry than it is in the technical literature ofmost other industries.B.Many of the highest-quality semiconductor patents are cited numerous times inthe technical literature.C.It is difficult for someone not familiar with the technical literature to recognizewhat constitutes an innovative semiconductor patent.D.There were more citations made per semiconductor patent in the technicalliterature in the 1970’s than in the 1980’s.E.Low-quality patents tend to be discussed in the technical literature as frequentlyas high-quality patents.Answer:------------------------------------------------------------------------------------------------------------ Q11:There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.8A.There are no legal limits, as there are for cod and haddock, on the size ofmonkfish that can be caught, a circumstance that contributes to their depletionthrough overfishing.B.There are no legal limits on the size of monkfish that can be caught, unlike cod orhaddock, a circumstance that contributes to depleting them because they are being overfished.C.There are legal limits on the size of cod and haddock that can be caught, but notfor monkfish, which contributes to its depletion through overfishing.D.Unlike cod and haddock, there are no legal size limits on catching monkfish,which contributes to its depletion by being overfished.E.Unlike catching cod and haddock, there are no legal size limits on catchingmonkfish, contributing to their depletion because they are overfished.Answer:------------------------------------------------------------------------------------------------------------ Q12:A certain automaker aims to increase its market share by deeply discounting its vehicles’ prices for the next several months.The discounts will cut into profits, but because they will be heavily advertised the manufacturer hopes that they will attract buyers away from rival manufacturers’ cars.In the longer term, the automaker envisions that customers initially attracted by the discounts may become loyal customers.In assessing the plan’s chances of achieving its aim, it would be most useful to know which of the following?A.Whether the automaker’s competitors are likely t o respond by offering deepdiscounts on their own productsB.Whether the advertisements will be created by the manufacturer’s currentadvertising agencyC.Whether some of the automaker’s models will be more deeply discounted thanothersD.Whether the automaker will be able to cut costs sufficiently to maintain profitmargins even when the discounts are in effectE.Whether an alternative strategy might enable the automaker to enhance itsprofitability while holding a constant or diminishing share of the marketAnswer:------------------------------------------------------------------------------------------------------------ Q13:With a record number of new companies starting up

inscriptions written in an alphabet date from the eighth century B.C., a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier.Significantly, the text of these earliest surviving Greek inscriptions sometimes runs from right to left and sometimes from left to right.Now, the Greeks learned alphabetic writing from the Phoenicians, and in the process they would surely have adopted whatever convention the Phoenicians were then using with respect to the direction of writing.Originally, Phoenicians writing ran in either direction, but by the eighth century B.C. it had been consistently written from right to left for about two centuries.In the argument given, the two portions in boldface play which of the following roles?A.The first
