Analytical Writing Assessment Question
Read the argument and the instructions that follow it, and then make any notes that will help you plan your response. Begin typing your response in the box at the bottom of the screen.
The following appeared as part of an article in the business section of a local newspaper.
"Motorcycle X has been manufactured in the United States for over 70 years. Although one foreign company has copied the motorcycle and is selling it for less, the company has failed to attract motorcycle X customers - some say because its product lacks the exceptionally loud noise made by motorcycle X. But there must be some other explanation. After all, foreign cars tend to be quieter than similar American-made cars, but they sell at least as well. Also, television advertisements for motorcycle X highlight its durability and sleek lines, not its noisiness, and the ads typically have voice-overs or rock music rather than engine-roar on the sound track.”
Discuss how well reasoned you find this argument. In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

文章：

In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Over the last few years, the number of Kravonians enrolled in college has been growing steadily. Therefore, the number of Kravonians entering the job market who have at least the qualification of a college degree will eventually be significantly higher than it has been over the last few years.

题目：

Which of the following, if true, most seriously weakens the argument?

选项:

A、Kravonians with more than one college degree earn little more, on average, than do Kravonians with only one college degree.The average number of years Kravonian college students remain enrolled before completing a degree has been increasing over the past several years.
B、Despite the increase in the number of Kravonians attending college, the percentage of the population attending college is lower in Kravonia than in most other countries. 
C、In recent years, employers have been requiring college degrees for workers in jobs that were previously performed successfully by Kravonians who did not have college degrees.
D、For many years, employers in Kravonia have had difficulty finding enough college graduates to fill the high-paying jobs that were available. 

答案:

B

Line         Manufacturers have to do more than build large
  manufacturing plants to realize economies of scale.
  It is true that as the capacity of a manufacturing
  operation rises, costs per unit of output fall as plant
(5) size approaches “minimum efficient scale,” where the
  cost per unit of output reaches a minimum,
  determined roughly by the state of existing technology
  and size of the potential market. However, minimum
  efficient scale cannot be fully realized unless a steady
(10) “throughput” (the flow of materials through a plant) is
  attained. The throughput needed to maintain the
  optimal scale of production requires careful
  coordination not only of the flow of goods through the
  production process, but also of the flow of input from
(15) suppliers and the flow of output to wholesalers and
  final consumers. If throughput falls below a critical
  point, unit costs rise sharply and profits disappear. A
  manufacturer’s fixed costs and “sunk costs” (original
  capital investment in the physical plant) do not
(20) decrease when production declines due to inadequate
  supplies of raw materials, problems on the factory
  floor, or inefficient sales networks. Consequently,
  potential economies of scale are based on the
  physical and engineering characteristics of the
(25) production facilities—that is, on tangible capital—but
  realized economies of scale are operational and
  organizational, and depend on knowledge, skills,
  experience, and teamwork—that is, on organized
  human capabilities, or intangible capital.
(30)      The importance of investing in intangible capital
  becomes obvious when one looks at what happens in
  new capital-intensive manufacturing industries. Such
  industries are quickly dominated, not by the first firms
  to acquire technologically sophisticated plants of
(35) theoretically optimal size, but rather by the first to
  exploit the full potential of such plants. Once some
  firms achieve this, a market becomes extremely hard
  to enter. Challengers must construct comparable
  plants and do so after the first movers have already
(40) worked out problems with suppliers or with new
  production processes. Challengers must create
  distribution networks and marketing systems in
  markets where first movers have all the contacts and
  know-how. And challengers must recruit management
(45) teams to compete with those that have already
  mastered these functional and strategic activities.


题目：

The passage suggests that which of the following is true of a manufacturer’s fixed and sunk costs?

选项:

A、The extent to which they are determined by market conditions for the goods being manufactured is frequently underestimated.
B、If they are kept as low as possible, the manufacturer is very likely to realize significant profits.
C、They are the primary factor that determines whether a manufacturer will realize economies of scale.
D、They should be on a par with the fixed and sunk costs of the manufacturer’s competitors.
E、They are not affected by fluctuations in a manufacturing plant’s throughput.

答案:

E

文章：

In 1955 Maurice Duverger published The Political Role of Women, the first behavioralist, multinational comparison of women's electoral participation ever to use election data and survey data together. His study analyzed women's patterns of voting, political candidacy, and political activism in four European countries during the first half of the twentieth century. Duverger's research findings were that women voted somewhat less frequently than men (the difference narrowing the longer women had the vote) and were slightly more conservative.

Duverger's work set an early standard for the sensitive analysis of women's electoral activities.

Moreover, to Duverger's credit, he placed his findings in the context of many of the historical processes that had shaped these activities. However, since these contexts have changed over time, Duverger's approach has proved more durable than his actual findings. In addition, Duverger's discussion of his findings was hampered by his failure to consider certain specific factors important to women's electoral participation at the time he collected his data: the influence of political regimes, the effects of economic factors, and the ramifications of political and social relations between women and men. Given this failure, Duverger's study foreshadowed the enduring limitations of the behavioralist approach to the multinational study of women's political participation.

题目：

The passage implies that, in comparing four European countries, Duverger found that the voting rates of women and men were most different in the country in which women

选项:

A、were most politically activeran for office most often
B、held the most conservative political views
C、had the most egalitarian relations with men
D、had possessed the right to vote for the shortest time

题目：

Educational Theorist: Recent editorials have called for limits on the amount of homework assigned to children. They point out that free-time activities
play an important role in childhood development and that large amounts of homework reduce children's free time, hindering their development. But the
average homework time for a ten year old, for example, is little more than 30 minutes per night. Clearly, therefore, there is no need to impose the limits these editorials are calling for.
 
Which of the following is an assumption on which the educational theorist's argument relies?

选项:

A、The free-time activities that ten year olds engage in most are all approximately equally effective at fostering development
B、Regularly doing homework assignments improves children's academic performance.
C、Individual teachers are not the best judges of how much homework to assign the children they teach
D、In most schools, if not all, the homework assignments given are of a length that does not diverge widely from the average.
E、Free-time activities rarely teach children skills or information that they can use in their academic work.

D

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
