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. Answer: ------------------------------------------------------------------------------------------------------------ Q28: Which of the following most logically completes the argument? A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______. A. histidine is found in all parts of the plant—roots, stem, leaves, and flowers B. the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids C. others of the closely related group of plants are also found to produce histidine in large quantities D. cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic E. the concentration of histidine in the growing herb declines as the plant approaches maturity Answer: ------------------------------------------------------------------------------------------------------------ Q29: Lofgren’s disease has been observed frequently in commercially raised cattle but very rarely in chickens. Both cattle and chickens raised for meat are often fed the type of feed that transmits the virus that causes the disease. Animals infected with the virus take more than a year to develop symptoms of Lofgren’s disease, however, and chickens

commercially raised for meat, unlike cattle, are generally brought to market during their first year of life. Which of the following is most strongly supported by the information provided? A. The virus that causes Lofgren’s disease cannot be transmitted to human beings by chickens. B. There is no way to determine whether a chicken is infected with the Lofgren’s disease virus before the chicken shows symptoms of the disease. C. A failure to observe Lofgren’s disease in commercial chicken populations is not good evidence that chickens are immune to the virus that causes this disease. D. An animal that has been infected with the virus that causes Lofgren’s disease but
