The argument above requires which of following assumptions?

选项:

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.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

During the past year, Pro-Tect Insurance Company's total payout on car-theft claims has been larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so it cannot protect itself against continued large payouts that way.  Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.  Many policyholders will respond to the discount by installing such devices, since the amount of the discount will within two years typically more than cover the cost of installation.  Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.
In the argument above, the two portions in boldface play which of the following roles?

Almost a decade after New York State passed laws to protect patients by reducing the grueling hours worked by medical residents, twelve hospitals have been investigated by state medical officials, finding that all twelve consistently break the laws, many residents work longer than 24 hours straight, and that more than half the surgical residents work more than 95 hours a week.
CDE比错了 认为意思是，许多人超过24小时，其中又有一半超过95小时，所以最后一句想用with；同时，C里面每个分句都用that引导，感觉麻烦，不用每个and后面都加that引导吧？

At present the Hollywood Restaurant has only standard-height tables.  However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities.  Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables.  Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.

The proliferation of so-called cybersquatters, people who register the Internet domain names of high-profile companies in hopes of reselling the rights to those names for a profit, led to passing the Anti-Cybersquatting Consumer Protection Act in 1999, allowing companies to seek up to $100,000 in damages against those who register domain names with the sole intent of selling them later.

Like those of the African white and black rhinos, the Sumatran rhino has two horns, but the front one is generally less than a foot long and the second is so small that it often appears to be missing.
