1. Advertisement: Our competitors’ computer salespeople are paid according to the value of the products they sell, so they have a financial incentive to convince you to buy the most expensive units—whether you need them or not. But here at Comput-o-Mart, our salespeople are paid a salary that is not dependent on the value of their sales, so they won’t try to tell you what to buy. That means when you buy a computer at Comput-o-Mart, you can be sure you’re not paying for computing capabilities you don’t need.
Which of the following would, if true, most weaken the advertisement’s reasoning?
A. Some less-expensive computers actually have greater computing power than more expensive ones.
B. Salespeople who have a financial incentive to make sales generally provide more attentive service than do other salespeople.
C. Extended warranties purchased for less-expensive computers can cost nearly as much as the purchase price of the computer.
D. Comput-o-Mart is open only limited hours, which makes it more difficult for many shoppers to buy computers there than at other retail stores.
E. Comput-o-Mart does not sell any computers that support only basic computing.
2.Clearbell Telephone provides slow-dialing (SD) service to customers for a low fee, and fast-dialing (FD) service to other customers who pay a somewhat higher fee. FD technology, however, is so efficient that it costs Clearbell substantially less per average call to provide than does SD. Nonetheless, accountants have calculated that Clearbell’s profits would drop if it provided FD to all its customers at the current low-fee rate.
Assume that installation costs for FD are insignificant if the customer already has SD service. Which of the following, if true about Clearbell, best explains the results of the accountants’ calculation?
A. The extra revenue collected from customers who pay the high fee is higher than the extra cost of providing SD to customers who pay the low fee.
B. The low fee was increased by 6 percent last year, whereas the higher fee was not increased last year.
C. Although 96 percent of customers regard FD service as reliable and more convenient than SD, fewer than 10 percent of them choose to pay the higher fee for FD service.
D. The company’s competitors generally provide business customers with FD service at low-fee rates.
E. Profits rose slightly each month for the first three months after FD was first offered to customers, then fell slightly each month for the succeeding three months.
