题目： More than 80% of the executives in the county attended high school in the county, and clearly they represent some of the brightest in the county. Among the seventeen high schools in the county, the three in the coastal towns have had the highest test scores in the county for several decades. A recent study shows that almost all of the county executives who attended high school in the county attended one of those three high schools in the coastal towns. The argument above is most vulnerable to criticism on which grounds?

题目： Two years ago, the human resources department at Harrison's Technologies had 175 sexual harassment cases open, a number that at that time led all companies in the sector. At that time, a typical claim took six months to process and clear. In response to this high number, the CEO's Advisory Team published a comprehensive set of guidelines for training employees in the identification and avoidance of behaviors that could constitute sexual harassment. At this writing, the human resources department has only sixty sexual harassment cases open. Clearly, the guidelines published by the CEO's Advisory Team were effective in reducing the occurrence of new sexual harassment claims at Harrison's Technologies. Which of the following, if true, most seriously weakens the conclusion above?

题目： The Dvorak keyboard requires less finger movement than the ubiquitous QWERTY keyboard. As a result, Dvorak keyboard users are not only able to type more words per minute, but are also less vulnerable to both repetitive stress disorder and carpal tunnel syndrome. Nonetheless, businesses, as well as consumers, have not adopted the Dvorak keyboard. Clearly, if the Dvorak keyboard is to become more widely used, its benefits must be more widely touted. Which of the following, if true, casts the most doubt on the author's conclusion?

Nevertheless, Zincstone Motors has chosen to eliminate the last two-door models and produce only four-door models.Which of the following would, if true, most help to explain Zincstone Motors' strategy?

题目： Dolphins can swim at high speeds and achieve high acceleration in the water. In 1936, Sir James Gray calculated the force dolphins should be able to exert based on their physiology. He concluded that the propulsive force they were able to exert was not enough to explain how fast they swim and accelerate. In the 2000s, experimenters used special computer-enhanced measurements of the water in which dolphins were swimming. Through mathematical modeling, they were able to measure the force dolphins exert with their tails. As it turns out, dolphins exert considerably more force with their tails than Sir James Gray or anybody else ever expected. Therefore, the force exerted by their tails easily explains how fast they swim and accelerate.In the argument, the two portions in boldface play which of the following roles?

题目： In social science research, "highest education level attained" would refer to the most advanced grade or degree achieved by an individual-for some individuals, it may be a grade in grade school, and for other individuals, it may be a Bachelor's Degree, a Master's Degree, or Ph.D. (which is considered the highest education level). A recent study has shown a strong correlation between highest education level attained and proficiency in chess. Another result, studied at many points throughout the 20th century, shows a marked positive correlation between highest education level attained and income level. Assuming the statements above are true, what conclusion can be drawn?

题目： In the last decade, the country of Alumba has undergone a massive construction boom. In one city, Semanta, hundreds of new buildings have been erected and, as a result, the ambient light at night has increased from 0.10 lux to 10 lux, causing migratory birds flying to alter their traditional path and fly into Semanta, where they often crash into buildings. The mayor believes that to ensure the birds keep to their traditional flight path while flying through Alumba, the city should turn off lights throughout the city at night during the bird's migratory season, so that ambient light is around 0.10 lux. Which of the following, is necessary, to evaluate the mayor's proposal for limiting the amount of night light that Semanta emits?

题目： The prevalence of a simian virus has been directly correlated with population density in gorillas. Recent fieldwork in the Republic of Dunaga, based on capturing gorillas and testing the gorillas for the virus, has shown that Morgania Plain gorillas are more than twice as likely to be infected than are the Koluga Mountain gorillas. Nevertheless, the population density of Koluga gorillas is significantly greater than that of Morgania gorillas. Which of the following could best account for the discrepancy noted above?

题目： Forty miles to the west of Tucson, a developer attempted to develop an "oasis" glade in the Sonoran Desert. He created a glade that, the developer claims, is as lush and plant-filled as the ambient 35° C temperatures allow. In particular, the developer planted several native fruit-bearing plants, such as prickly-pear cactus. Once the glade was established, a number of desert birds and mammals would regularly inhabit the glade, often eating most of the fruit that falls from the plants. The considerations given best serve as part of an argument that:
