Q21: Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers’ report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically. Which of the following would it be most useful to know in order to evaluate the argument? A. Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed B. Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops C. Whether for most farmers who grow cotton it is their primary crop D. Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did E. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide Answer: ----------------------------------------------------------------------------------------------------------- - Q22: The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale. The argument above is flawed because it fails to take into account 11

----------------------------------------------------------------------------------------------------------- - Q23 to Q25: Companies that must determine well in advance of the selling season how many unites of a new product to manu- Line facture often underproduce products (5) that sell well and have overstocks of others. The increased incidence in recent years of mismatches between production and demand seems ironic, since point-of-sale scanners have (10) improved data on consumers’ buying patterns and since flexible manufac- turing has enabled companies to produce, cost-effectively, small quantities of goods. This type of (15) manufacturing has greatly increased the number of new products introduced annually in the United States. However, frequent introductions of new products have two problematic side effects. For (20) one, they reduce the average lifetime of products; more of them are neither at the beginning of their life (when prediction is difficult) or at the end of their life

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
