- Question 1 of 7
Proposed new safety rules for Beach City airport would lengthen considerably the minimum time between takeoffs from the airport. ln consequence, the airport would be able to accommodate 10 percent fewer flights than currently use the airport daily. The city’s operating budget depends heavily on taxes generated 532 by tourist spending, and most of the tourists come by plane. Therefore, the proposed new safety rules, if adopted, will reduce the revenue available for the operating budget.

- Question 2 of 7
As a construction material, bamboo is as strong as steel and sturdier than concrete. Moreover, in tropical areas bamboo is a much less expensive construction materialthan either steel or concrete and is always readily available. ln tropical areas, therefore, building with bamboo makes better economic sense than building with steel or concrete, except where land values are high.
Which of the following, if true, most helps to explain the exception noted above?CorrectIncorrect
- Question 3 of 7
Scientists have modified feed corn genetically, increasing its resistance to insect pests. Farmers who tried out the genetically modified corn last season applied less insecticide to their corn fields and still got yields comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less, and what these farmers saved on insecticide rarely exceeded their extra costs for seed. Therefore, for most feed-corn farmers, switching to genetically modified seed would be unlikely to increase profits.
Which of the following would it be most useful to know in order to evaluate the argument?CorrectIncorrect
- Question 4 of 7
Proponents of the recently introduced tax on sales of new luxury boats had argued that a tax of this sort would be an equitable way to increase government revenue because the admittedly heavy tax burden would fall only on wealthy people and neither they nor anyone else would suffer any economic hardship. ln fact, however, 20 percent of the workers employed by manufacturers of luxury boats have lost their jobs as a direct result of this tax.
The information given, if true, most strongly supports which of the following?CorrectIncorrect
- Question 5 of 7
ln the past the country of Malvernia has relied heavily on imported oil. Malvernia recently implemented a program to convert heating systems from oil to natural gas. Malvernia currently produces more natural gas each year than it uses, and oil production in Malvernian oil fields is increasing at a steady pace. lf these trends in fuel production and usage continue, therefore, Malvernian reliance on foreign sources for fuel is likely to decline soon.
Which of the following would it be most useful to establish in evaluating the argument?CorrectIncorrect
- Question 6 of 7
Normally, the pineal gland governs a person’s sleep-wake cycle by secreting melatonin in response to the daily cycle of light and darkness as detected by the eye. Nonetheless, many people who are totally blind due to lesions in the visual cortex of the brain easily maintain a 24-hour sleep-wake cycle, So the neural pathway by which the pineal gland receives information from the eye probably does not pass through the visual cortex.
For purposes of evaluating the argument it would be most useful to establish which of the following?CorrectIncorrect
- Question 7 of 7
Last year Comfort Airlines had twice as many delayed flights as the year before, but the number of complaints from passengers about delayed flights went up three times. lt is unlikely that this disproportionate increase in complaints was rooted in an increase in overall dissatisfaction with the service Comfort Airlines provides, since the airline made a special effort to improve other aspects of its service last year.
Which of the following, if true, most helps to explain the disproportionate increase in customer complaints?CorrectIncorrect
