Q1) In 1979 approximately 1/3 of the 37.3 million airline passengers traveling to or from the United States used Kennedy Airport. If the number of such passengers that used Miami Airport was 1/2 the number that used Kennedy Airport and 4 times the number that used Logan Airport, approximately how many millions of these passengers used Logan Airport that year?
Q2) Last year Mrs. Long received 160 Dollar in dividends on her shares of Company X stock, all of which she had held for the entire year.

Reading Comprehension ---- A recent worldwide decline of ocean fishery stocks has stimulated rapid growth in cultivated production of fish and shellfish, usually known as fish farming. Between 1987 and 1997, for example, global fish production from farming doubled. Fish farming produces a quarter of all fish and shellfish eaten by humans, and, as global population increases, fish farming will probably become even more important in supplying human protein needs. Some experts even argue that in addition to helping to compensate for the decline in ocean harvests, fish farming will restore wild populations by relieving pressure on ocean fisheries. There is, however, little if any evidence that fish farming will restore ocean fishery stocks. The complexity of production systems leads to an underlying paradox: fish farming is a possible solution, but also a potential contributing factor, to the continued decline of ocean fishery stocks worldwide. In the first place, the more intensive forms of fish fanning, oriented toward high-volume production, threaten the sustainability of ocean fisheries through water pollution and ecological disruption. Intensive fish farming usually involves the enclosure of fish in a secure system; population densities are typically high, resulting in the generation of large amounts of waste and increased potential for the spread of pathogens. Habitat destruction through the spread of untreated waste, the escape of species not native to the farm's region, or contamination by new pathogens can all ensue, seriously damaging ocean and coastal resources and, ultimately, wild fishery stocks. Even more important, intensive farming of many species of fish requires large inputs of fish meal and fish oil in order to supply fatty acids that vegetable matter lacks or essential amino acids that it inadequately supplies, like lysine and methionine. For the ten species of fish most commonly farmed, an average of 1.9 kilograms of wild fish is required for every kilogram of fish produced. Of the ten species, only three—catfish, milkfish, and carp—require less fish input than is eventually harvested, while the farming of carnivorous species like salmon has a very high input-to-output ratio. Although some defenders of fish fanning contend that predatory carnivores in the wild consume even more fish than they would on a farm, farming of such carnivorous species requires up to 5 kilograms of wild fish for every kilogram of fish produced. Expanding farm production does have the potential to alleviate some of the pressure on wild fishery stocks. For example, increasing the farm production of fish like salmon can reduce prices, deterring investment in fishing fleets and, over time, reducing fishing efforts. Similarly, other farmed fish like tilapia and channel catfish provide alternatives to ocean fish like cod and haddock. Nonetheless, even these benefits may in the end be lost because niche markets have started to develop for several species of wild-caught fish, causing their catch rates to remain high even as the production of viable farmed substitutes has increased.

These new ideas could have a profound impact on the diagnosis of strictures, especially since the medications generally given to surgical patients mask the obvious warning signs of bile duct strictures. In the past, those suffering from such strictures would exhibit telltale symptoms - an oozing of pus from the pores of the chest and a dark discoloration of the urine and saliva. But the prevalent use of multivitamins and antibiotics keeps these symptoms hidden in patients, giving doctors no external indications of a problem in the bile duct system. Doctors have had to resort to other methods of detection, primarily biopsy through either traditional means or endoscopy. However, even micro endoscopy is enough of an invasive technique that the procedure itself could provoke the same reaction that may cause bile duct strictures. Newer, noninvasive technologies such as MRI (magnetic resonance imaging) or ultrasound could, thus, prove to be beneficial. Still, even these techniques are not useful unless the approximate location of the stricture is known. Without some empirical evidence of where the blockage is occurring or some theory that could successfully pinpoint its locale, an ultrasound scan could be a quixotic endeavor.
Q9) The author’s primary purpose in this passage is to
Q10) It can be inferred from the passage that a doctor who wishes to detect the presence of a bile duct stricture within a patient would have the most success by performing which of these procedures?
Q11) The passage suggests that which of the following would lead to the easiest detection of possible bile duct strictures?

Q12) Current farm policy is institutionalized penalization of consumers. It increases food prices for middle- and low-income families and costs the taxpayer billions of dollars a year. Which of the following statements, if true, would provide support for the author’s claims above? I. Farm subsidies amount to roughly $20 billion a year in federal payouts and $12 billion more in higher food prices. II. According to a study by the Department of Agriculture, each $1 of benefits provided to farmers for ethanol production costs consumers and taxpayers $4. III. The average full-time farmers have an average net worth of over $300,000.

Q13) Which of the following best completes the passage below? In today’s pluralistic society, textbook publishers find themselves in an increasingly uncomfortable position. Since the schools are regarded as a repository of society’s moral and cultural values, each group within society wishes to prevent any material that offends its own values from appearing in textbooks. As a result, stance on an issue is certain to run afoul of one group or another. And since textbook publishers must rely on community goodwill to sell their books, it is inevitable that______

Q14) Manufacturers of household appliances are still urging the public to purchase food processors. The various manufacturers’ advertisements all point out that the prices of these appliances are now lower than ever and that each food processor comes with a lifetime service warranty. In addition, many manufacturers offer sizable rebates to customers who purchase food processors within a given time period. With these incentives, the advertisements contend, people can hardly afford not to purchase food processors. Which answer choice is a logically prior issue that the manufacturers’ advertisements fail to address?

Q15) Some analysts maintain that an embargo by country Litora on the export of a strategic metal to country Zenda, if imposed, would drive up the price of the metal in Zenda at least tenfold. They note that few other countries export the metal and that, with an embargo, Zenda might have to depend on as-yet-unexploited domestic sources of the metal. Which of the following, if true, constitutes the most serious objection to the analysis above?
