A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.

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?

想问问郭培月老师，这道题能明显排除BDE，但是A和C我选了A，因为感觉说revenue collected from customer who pay high fee跟extra cost of SD比较，跟原文说如果provide FD，利润会下降这一点无关，C说顾客不愿意买FD，感觉更相关，麻烦老师指出这样想的错误的地方，以及分析考场上应该如何思考这两个选项
