OG12 OG15 OG16 OG17 OG18 OG19 OG20 OG2022	Several industries have recently switched at least partly from older technologies powered by fossil fuels to new technologies powered by electricity.

OG15 OG16 OG17	The following appeared in a memorandum from a company's marketing department:"Since our company started manufacturing and marketing a deluxe air filter six months ago, sales of our economy filter—and company profits—have decreased significantly. The deluxe air filter sells for 50 percent more than the economy filter, but the economy filter lasts for only one month while the deluxe filter can be used for two months before it must be replaced. To increase repeat sales of our economy filter and maximize profits, we should discontinue the deluxe air filter and concentrate all our advertising efforts on the economy filter."Discuss how well reasoned you find this argument. In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

OG12 OG15 OG16 OG17 OG18 OG19 OG20 OG2022	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?
OG15 OG16 OG17	The following appeared in a memorandum from the president of a company that makes shampoo:"A widely publicized study claims that HR2, a chemical compound in our shampoo, can contribute to hair loss after prolonged use.

Therefore, we do not need to consider replacing the HR2 in our shampoo with a more expensive alternative."Discuss how well reasoned you find this argument.
