This passage was adapted from an article written in 1990.
Research data indicate that
there is a great deal of poverty in
the United States among single-
Line parent families headed by women.
(5) This problem could result from
the fact that women’s wages are
only 60 percent of men’s. Some
economists believe that rigorous
enforcement of existing equal pay
(10) laws would substantially decrease
this wage inequity. But equal pay
laws are ineffectual when women
and men are concentrated in different
occupations because such laws
(15) require only that women and men
doing the same jobs be paid the
same. Since gender concentration
exists (for example, 80 percent of
clerical workers are women), other
(20) economists argue that a comparable
worth standard, which would
mandate that women and men in
any jobs that require comparable
training and responsibility be paid
(25) the same, should be applied
instead. But some policy analysts
assert that, although comparable
worth would virtually equalize male
and female wages, many single-
(30) parent families headed by women
would remain in poverty because
many men earn wages that are
below the poverty line. These
policy analysts believe that the
(35) problem is not caused primarily by
wage inequity but rather by low
wages coupled with single parent
hood, regardless of sex. As a
solution, they challenge the govern-
(40) ment’s assumption that a family’s
income should depend primarily on
wages and urge the government to
provide generous wage supplements
(child and housing allow-
(45) ances) to single parents whose
wages are low.
GWD 21-35
The passage suggests that the United States government’s policy towards providing wage supplements to parents whose wages are low is
A. considered ill advised by most economists who have studied the issue
B. based on assumptions about the appropriate sources of family income
C. under revision in response to criticism from some policy analysts
D. capable of eliminating wage inequality but not of raising incomes for both women and men
E. applicable to single-parent families headed by women but not to single-parent families headed by men
GWD 21-36
Which of the following is most clearly an example of the policy advocated by the policy analysts mentioned in line 26 ?
A. A government provides training to women who wish to move out of occupations in which women are concentrated.
B. A government supports research that analyzes the connection between wage inequality and poverty among single-parent families headed by women.
C. A government surveys wages annually to make certain that women and men in the same jobs receive the same pay.
D. A government analyzes jobs in terms of the education and responsibility they require and publishes a list of jobs that should be considered equivalent for wage purposes.
E. A government provides large rent subsidies to single parents whose wages are less than half the average worker’s wage.
GWD 21-37
According to the passage, some economists believe that, in the United States, there would be smaller differences between the wages of women and men who do the same jobs if
A. equal pay laws were enforced more fully
B. more stringent equal pay laws were passed
C. a more rigorous comparable worth standard were developed and applied
D. more men entered the occupations in which women are concentrated
E. women received the same kind and amount of job training that men receive

28-passage one
Social learning in animals is said to occur when direct or indirect social interaction facilitates the acquisition of a novel behavior. It usually takes the form of an experienced animal (the demonstrator) performing a behavior such that the naïve animal (the observer) subsequently expresses the same behavior sooner, or more completely, than it would have otherwise. One example of social learning is the acquisition of preferences for novel foods. Some experiments have suggested that among mammals, social learning facilitates the identification of beneficial food items, but that among birds, social learning helps animals avoid toxic substances. For example, one study showed that when red-wing blackbirds observed others consuming a colored food (30) or a food in a distinctly marked container and then becoming ill, they subsequently avoided food associated with that color (35) or container. Another experiment showed that house sparrows consumed less red food after they observed others eating (40) red food that was treated so as to be noxious. Studies on non-avian species have not produced similar results, leading researchers to speculate that avian social learning may be fundamentally different from that of mammals.
But Sherwin's recent (50) experiments with domestic hens do not support the notion that avian social learning necessarily facilitates aversion to novel (55) foods that are noxious or toxic. Even when demonstrator hens reacted with obvious disgust to a specific food, via vigorous head (60) shaking and bill wiping, there was no evidence that observers subsequently avoided eating that food. Sherwin's research team speculated that ecological or social constraints during the evolution of this species might have resulted in there being little benefit from the social learning of atability, for instance, selective pressures for this mode of learning would be reduced if the birds rarely encountered noxious or toxic food or rarely interacted after eating such food, or if the consequences of ingestion were minimal. (80) In a related experiment the same researchers showed that if observer hens watched demonstrator hens react favorably to food of a particular color, then observer hens ate more food of that color than they ate of food of other colors. These results confirmed that avian species can develop preferences for palatable food through social learning.
28-3: The primary purpose of the passage is to discuss the
A: techniques used in certain experiments on social learning in birds
B: reasons for the differences between social learning in birds and in mammals
C: question of how social learning manifests itself in birds
D: basis for a widespread belief about a difference in behavior between birds and mammals
E: possible reasons why birds may or may not learn from each other in a particular way
28-4: missing
28-5: According to the passage, which of the following is true of the experiments on domestic hens conducted by Sherwin’s research team?
A: Only a small number of observer hens appeared to learn to avoid food that was demonstrated by other hens to be noxious.
B: Observer hens ingested food preferentially only after numerous instances of witnessing demonstrator hens preferentially ingest that type of food.
C: Observer hens appeared unable to recognize when demonstrator hens found a particular food especially palatable.
D: Observer hens appeared unable to recognize when demonstrator hens found a particular food especially palatable.
E: Demonstrator hens altered their behavior less obviously in response to noxious foods than in response to highly palatable foods.
28-6: It can be inferred that the author of the passage would be most likely to agree with which of the following statements regarding the results of the recent experiments conducted by Sherwin’s research team?
A: The experiments demonstrate that social learning in avian species facilitates the identification of noxious or toxic foods.
B: The experiments suggest that social learning has made avian species less adept than nonavian species at learning to prefer beneficial foods and avoid noxious and toxic foods.
C: The experiments undermine the notion that most avian species have evolved in environments where there is little benefit to the social learning of unpalatability.
D: The experiments suggest that the acquisition of food preferences in avian species is largely unaffected by social learning.
E: The experiments show that social learning in avian species can promote the preferential consumption of beneficial foods but do not support the claim that social learning in avian species promotes the avoidance of noxious or toxic foods.
28-passage two
Carotenoids, a family of natural pigments, form an important art of the colorful signals used by many animals. Animals acquire carotenoids either directly (from the plants and algae that produce them) or indirectly (by eating insects) and store them in a variety of tissues. Studies of several animal species have shown that when choosing mates, females prefer males with brighter carotenoid-based coloration. Owens and Olson hypothesize that the presence of carotenoids, as signaled by coloration, would be meaningful in the context of mate selection if carotenoids were either rare or required for health. The conventional (Line 15) view is that carotenoids are meaningful because they are rare: healthier males can forage for more of the pigments than can their inferior counterparts. Although this may be true, there is growing evidence that carotenoids are meaningful also because they are required: they are used by the immune system and for detoxification processes that are important for maintaining health. It may be that males can use scarce carotenoids either for immune defense and detoxification or for attracting females. Males that are more susceptible to disease and parasites will have to use their carotenoids to boost their immune systems, whereas males that are genetically resistant will use fewer carotenoids for fighting disease and will advertise this by using the pigments for flashy display instead.
28-13: Information in the passage suggests that which of the following is true of carotenoids that a male animal uses for detoxification processes?
A: They were not acquired directly from plants and algae
B: They cannot be replenished through foraging.
C: They cannot be used simultaneously to brighten coloration.
D: They do not affect the animal’s susceptibility to parasites.
E: They increase the chances that the animal will be selected as a mate.
28-14: The passage suggests that relatively bright carotenoid-based coloration is a signal of which of the following characteristics in males of certain animal species?
A: Readiness for mating behavior
B: Ability to fight
C: Particular feeding preferences
D: Recovery from parasite infestation
E: Fitness as a mate
28-15: According to the “conventional view” referred to in lines 14-15 of the passage, brighter carotenoid-based coloration in certain species suggests that an individual
A: lives in a habitat rich in carotenoid-bearing plants and insects
B: has efficient detoxification processes
C: has a superior immune system
D: possesses superior foraging capacity
E: is currently capable of reproducing
28-passage three
Many politicians, business leaders, and scholars discount the role of public policy and emphasize the role of the labor market when explaining employers' maternity-leave policies, arguing that prior to the passage of the Family and Medical Leave Act (FMLA) of 1993, employers were already providing maternity leave in response to the increase in the number of women workers. Employers did create maternity-leave programs in the 1970's and 1980's, but not as a purely voluntary response in the absence of any government mandate. In 1972, the Equal Employment Opportunity Commission (EEOC) ruled that employers who allowed leaves for disabling medical conditions must also allow them for maternity and that failure to do so would constitute sex discrimination under the Civil Rights Act of 1964. As early as 1973, a survey found that 58 percent of large employers had responded with new maternity-leave policies. Because the 1972 EEOC ruling was contested in court, the ruling won press attention that popularized maternity-leave policies. Yet perhaps because the Supreme Court later struck down the ruling, politicians and scholars have failed to recognize its effects, assuming that employers adopted maternity-leave policies in response to the growing feminization of the workforce.
28-25: It can be inferred that the author of the passage would be most likely to agree with which of the following statements about government policy?
A: Government policy is generally unaffected by pressures in the labor market.
B: The impact of a given government policy is generally weakened by sustained press attention.
C: It is possible for a particular government policy to continue to have an impact after that policy has been eliminated.
D: A given government policy can be counterproductive when that policy has already unofficially been implemented.
E: The impact of a given government policy is generally weakened when the ruling is contested in court.
28-26: missing
28-27: The passage suggests that the relationship between the view of the author with respect to maternity leave policy prior to passage of the FMLA and the view of the politicians, business leaders, and scholars mentioned in lines 1-2 can best be characterized by which of the following statements?
A: They agree that both the 1972 EEOC ruling on maternity-leave policy and the increasing feminization of the workplace had an impact on employers’ creation of maternity-leave programs but disagree about the relative importance of each factor.
B: They agree that the EEOC ruling on maternity-leave policy had an initial impact on employers’ creation of maternity-leave programs but disagree over whether the Supreme Court’s striking down of the EEOC ruling weakened that impact.
C: They agree that creating maternity-leave programs was a necessary response to the needs of the increasing number of women workers but disagree about whether maternity should be classified as a disabling medical condition.
D: They agree that employers created maternity-leave programs prior to passage of the FMLA but disagree about employers’ motivations for doing so.
E: They agree that employers created maternity-leave programs prior to passage of the FMLA but disagree about how widespread those programs were.
28-passage four
Customer loyalty programs are attempts to bond customers to a company and its products and services by offering incentives – such as airline frequent flyer programs or special credit cards with valuable benefits – to loyal customers. In support of loyalty programs, companies often invoke the "80/20" principle, which states that about 80 percent of revenue typically comes from only about 20 percent of customers. However, this profitable 20 percent are not necessarily loyal buyers, especially in the sense of exclusive loyalty. Studies have demonstrated that only about 10 percent of buyers for many types of frequently purchased consumer goods are 100 percent loyal to a particular brand over a one-year period. Moreover, 100-percent-loyal buyers tend to be light buyers of the product or service. "Divided loyalty" better describes actual consumer behavior, since customers typically vary the brands they buy. The reasons for this behavior are fairly straightforward: people buy different brands for different occasions or for variety, or a brand may be the only one in stock or may offer better value because of a special deal. Most buyers who change brands are not lost forever; usually, they are heavy consumers who simply (35) prefer to buy a number of brands. Such multi-brand loyalty means that one company's most profitable customers will probably be its competitors' most profitable customers as well. (40) Still, advocates of loyalty programs contend that such programs are beneficial because the costs of serving highly loyal customers are lower, and because such loyal customers are less price sensitive than other customers. It is true that when there are start-up costs, such as credit checks, involved in serving a new customer, the costs exceed those of serving a repeat customer. However, it is not at all clear why the costs of serving a highly loyal customer should in principle be different from those of serving any other type of repeat customer. The key variables driving cost are size and type of order, special versus standard order, and so on, not high-loyalty versus divided-loyalty customers. As for price sensitivity, highly loyal customers may in fact come to expect a price discount as a reward for their loyalty.
33: The primary purpose of the passage is to
A: question the notion that customer loyalty programs are beneficial
B: examine the reasons why many customers buy multiple brands of products
C: propose some possible alternatives to customer loyalty programs
D: demonstrate that most customers are not completely loyal to any one brand of product or service
E: compare the benefits of customer loyalty programs with those of other types of purchase incentive programs |
