Question 11/20:
The idea that equipping homes with electrical appliances and other “modern” household technologies would eliminate drudgery, save labor time, and increase leisure for women who were full-time home workers remained largely unchallenged until the women’s movement of the 1970’s spawned the groundbreaking and influential works of sociologist Joann Vanek and historian Ruth Cowan. Vanek analyzed 40 years of time-use surveys conducted by home economists to argue that electrical appliances and other modern household technologies reduced the effort required to perform specific tasks, but ownership of these appliances did not correlate with less time spent on housework by full-time home workers. In fact, time spent by these workers remained remarkably constant—at about 52 to 54 hours per week—from the 1920’s to the 1960’s, a period of significant change in household technology. In surveying two centuries of household technology in the United States, Cowan argued that the “industrialization” of the home often resulted in more work for full-time home workers because the use of such devices as coal stoves, water pumps, and vacuum cleaners tended to reduce the workload of married-women’s helpers (husbands, sons, daughters, and servants) while promoting a more rigorous standard of housework. The full-time home worker’s duties also shifted to include more household management, child care, and the post-Second World War phenomenon of being “Mom’s taxi.”
According to the passage, which of the following is true about the idea mentioned in the highlighted text?
A.It has been undermined by data found in time-use
surveys conducted by home economists.
B.It was based on a definition of housework that was
explicitly rejected by Vanek and Cowan.
C.It is more valid for the time period studied by
Cowan than for the time period studied by Vanek.
D.It is based on an underestimation of the time that
married women spent on housework prior to the
industrialization of the household.
E.It inaccurately suggested that new household
technologies would reduce the effort required to
perform housework.

Question 14/20:
In recent years, Western business managers have been heeding the exhortations of business journalists and academics to move their companies toward longterm, collaborative “strategic partnerships” with their external business partners (e.g., suppliers). The experts’ advice comes as a natural reaction to numerous studies conducted during the past decade that compared Japanese production and supply practices with those of the rest of the world. The link between the success of a certain well-known Japanese automaker and its effective management of its suppliers, for example, has led to an unquestioning belief within Western management circles in the value of strategic partnerships. Indeed, in the automobile sector all three United States manufacturers and most of their European competitors have launched programs to reduce their total number of suppliers and move toward having strategic partnerships with a few.
However, new research concerning supplier relationships in various industries demonstrates that the widespread assumption of Western managers and business consultants that Japanese firms manage their suppliers primarily through strategic partnerships is unjustified. Not only do Japanese firms appear to conduct a far smaller proportion of their business through strategic partnerships than is commonly believed, but they also make extensive use of “marketexchange” relationships, in which either party can turn to the marketplace and shift to different business partners at will, a practice usually associated with Western manufacturers.
The passage is primarily concerned with
A.examining economic factors that may have
contributed to the success of certain Japanese
companies
B.discussing the relative merits of strategic
partnerships as compared with those of marketexchange
relationship
C.challenging the validity of a widely held assumption
about how Japanese firms operate
D.explaining why Western companies have been slow
to adopt a particular practice favored by Japanese
companies
E.pointing out certain differences between Japanese
and Western supplier relationships

Question 19/20:
A fruit known as amla in certain parts of Asia is an excellent source of vitamin (C) A small quantity of the fruit grated and added to salads provides almost all the daily requirement of this vitamin. However, the fruit is very sour. A new process designed to remove most of the sour taste will make the fruit acceptable to American tastes. We are therefore starting to grow this fruit for sale in the United States.

A. Americans generally won’t eat very sour foods
B. The new process does not remove a significant part of the vitamin content
C. That a market exists for a new source of vitamin C
D. The fruit can be used only in salads
E. Apart from being sour there are no other objections to eating this fruit
Question 20/20:
Most scientists agree that new lines of interdisciplinary research are the need of the hour. Even government committees on science have stressed the need for more interdisciplinary projects. Yet, often proposals for new interdisciplinary projects last year, only one was successfully funded Some have suggested that this means that as yet researchers are not coming up with sufficiently persuasive projects, or that their proposals are not of high enough quality, or even that the reputations of these researchers is not high enough. However, the real reason probably lies in the way funding is organized Funding is still allocated according to the old categories and there are no funds specifically for research that overlaps different subject areas.

B. The first is a finding that the author attempts to account for; the second is a finding that contradicts the author’s main conclusion.
C.The first is a fact that the author attempts to account for. The second is data that explicitly supports the author’s main conclusion.
D. The first is a position that the author opposes; the second is the author’s main position
E. The first is a situation that the author finds paradoxical; the second is an assumption that the author uses to reinforce the paradox.
Question 1/20:
Companies that must determine well in advance of the selling season how many unites of a new product to manufacture often under-produce products that sell well and have overstocks of others. The increased incidence in recent years of mismatches between production and demand seems ironic, since point-ofsale scanners have improved data on consumers’ buying patterns and since flexible manufacturing has enabled companies to produce, cost-effectively, small quantities of goods. This type of manufacturing has greatly increased the number of new products introduced annually in the United States. However, frequent introductions of new products have two problematic side effects. For one, they reduce the average lifetime of products; more of them are neither at the beginning of their life (when prediction is difficult) or at the end of their life (when keeping inventory is expensive because the products will soon become obsolete). For another, as new products proliferate, demand is divided among a growing number of stock-keeping units (SKU’s). Even though manufacturers and retailers can forecast aggregate demand with some certainty, forecasting accurately how that demand will be distributed among the many SKU’s they sell is difficult. For example, a company may be able to estimate accurately the aggregate number of shoes it will sell, but it may be uncertain about which specific types of shoes will sell more than other types.
Which of the following most accurately describes the function of the last sentence in the passage?
A. To cite a situation in which the aggregate demand
is more important than the distribution of demand
among SKU’s
B. To refute an assertion about the side effects of
flexible manufacturing
C. To illustrate an assertion about companies’ ability to
forecast demand
D. To provide an example of ways in which companies
address the difficulties of forecasting demand
E. To note an exception to the author’s assertion
about distributing demand among SKU’s
Question 2/20:

For example, a company may be able to estimate accurately the aggregate number of shoes it will sell, but it may be uncertain about which specific types of shoes will sell more than other types.
The passage suggests which of the following about divided demand among a growing number of SKU’s?
A. It has increased the average lifetime of products.
B. It has resulted from retailer’s attempts to predict
demand more accurately and avoid both understocks
and overstocks.
C. It has decreased the use of flexible manufacturing
by companies.
D. It has not increased the expense of keeping
inventory of certain products.
E. It has not prevented companies from predicting
aggregate demand with some certainty.
Question 3/20:
Companies that must determine well in advance of the selling season how many unites of a new product to manufacture often under-produce products that sell well and have overstocks of others.

According to the passage, which of the following has led to growth in the number of new products introduced in the United States each year?
A. Reduced average lifetime of products
B. Increased ability to forecast aggregate demand
C. More cost-effective ways of keeping inventory for
products
D. Cost-effective production of small quantities of
goods
E. Increased ability to divide demand among a number
of SKU’s and to forecast how that demand will be
distributed among those SKU’s
Question 4/20:
Until recently, zoologists believed that all species of phocids (true seals), a pinniped family, use a different maternal strategy than do otariids (fur seals and sea lions), another pinniped family. Mother otariids use a foraging strategy. They acquire moderate energy stores in the form of blubber before arriving at breeding sites and then fast for 5 to 11 days after birth. Throughout the rest of the lactation (milk production) period, which lasts from 4 months to 3 years depending on the species, mother otariids alternately forage at sea, where they replenish their fat stores, and nurse their young at breeding sites. Zoologists had assumed that females of all phocid species, by contrast, use a fasting strategy in which mother phocids, having accumulated large energy stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species. However, recent studies on harbor seals, a phocid species, found that lactating females commenced foraging approximately 6 days after giving birth and on average made 7 foraging trips during the remainder of their 24-day lactation period. The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation. Harbor seals are small compared with other phocid species such as grey seals, northern elephant seals, and hooded seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smaller than many other phocids, harbor seals are similar in size to most otariids. In addition, there is already some evidence suggesting that the ringed seal, a phocid species that is similar in size to the harbor seal, may also use a maternal foraging strategy.
It can be inferred from the passage that the females of all phocid species differ from the females of all otariid species in that the female phocids
A. have shorter lactation periods
B. consume more food during lactation
C. consume a higher proportion of fat stores
D. forage for food occasionally during their lactation
periods
E. deplete a smaller percentage of their fat stores
during their lactation periods

Question 6/20:
Until recently, zoologists believed that all species of phocids (true seals), a pinniped family, use a different maternal strategy than do otariids (fur seals and sea lions), another pinniped family. Mother otariids use a foraging strategy. They acquire moderate energy stores in the form of blubber before arriving at breeding sites and then fast for 5 to 11 days after birth. Throughout the rest of the lactation (milk production) period, which lasts from 4 months to 3 years depending on the species, mother otariids alternately forage at sea, where they replenish their fat stores, and nurse their young at breeding sites. Zoologists had assumed that females of all phocid species, by contrast, use a fasting strategy in which mother phocids, having accumulated large energy stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species. However, recent studies on harbor seals, a phocid species, found that lactating females commenced foraging approximately 6 days after giving birth and on average made 7 foraging trips during the remainder of their 24-day lactation period. The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation. Harbor seals are small compared with other phocid species such as grey seals, northern elephant seals, and hooded seals, all of which are known to fast for the entire lactation period. Studies show that mother seals of these species use respectively 84 percent, 58 percent, and 33 percent of their fat stores during lactation. By comparison, harbor seals use 80 percent of their fat stores in just the first 19 days of lactation, even though they occasionally feed during this period. Since such a large proportion of their fat stores is exhausted despite feeding, mother harbor seals clearly cannot support all of lactation using only energy stored before giving birth. Though smaller than many other phocids, harbor seals are similar in size to most otariids. In addition, there is already some evidence suggesting that the ringed seal, a phocid species that is similar in size to the harbor seal, may also use a maternal foraging strategy.
According to the passage, until recently zoologists believed which of the following about all phocid mothers?
A. Their fasting periods after giving birth were typically
shorter than those of otariids.
B. Their lactation periods were generally as long as
those of comparably sized otariids
C. They acquired only moderate energy stores in the
form of blubber before arriving at breeding sites.
D. They depleted less than a third of their stored body
fat during lactation.
E. The replenished their fat stores only after their
lactation period ended.

strategy may be related to their small size
Question 8/20:
Anton: I sold my house on an internet site last year and was happy with the price I got a speedy sale and the cost of advertising was insignificant. I would advise you to avoid real estate agents. Barbie: It is in the interest of the real estate agent to get me the best price for my property because he gets a commission based on the selling price Therefore, when selling my house I will certainly use an agent rather than trying to sell the house by word of mouth, or by advertising in newspapers or on the internet.
Barbie’s could strengthen her position by pointing out all of the following EXCEPT
A. Houses of comparable value often obtain a lower price when sold on the internet
B. Very few houses are sold on the internet at the moment and a valid comparison is difficult
C. The agent’s service includes many add-on benefits in terms of legal fees, surveyor’s reports and advice that are not available on internet sites
D. Some buyers pay the agent to find them a cheap house
E. The agent’s commission is usually less than the difference between the internet price and the higher price the agent obtains for you
Question 9/20:
Early data on seat-belt use showed that seat-belt wearers were less likely to be killed in road accidents. Hence, it was initially believed that wearing a seat-belt increased survival chances in an accident. But what the early analysts had failed to see was that cautious drivers were more likely to wear the belts and were also less likely to cause ‘big accidents’, while reckless drivers were more likely to be involved in ‘big’ accidents and were less likely to wear the belts.
Which of the following, if true, could an opponent of the view presented above best cite as a reason for recommending continued use of seat-belts?
A.Careful drivers who are involved in accidents caused by reckless drivers, would be more likely to survive if wearing a belt
B.All drivers should be required by law to wear a belt
C.The ratio of ‘big’ to ‘small’ road accidents is very small
D. In fatal accidents seat-belt wearers in the front seat are less likely to survive than those wearing seat belts in the back seat
E. On average, careful drivers pay lower insurance premiums than do drivers who have been involved in accidents.
