题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

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.

Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers.  This population's descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland.  Tufe Island is significantly drier than Tufe Peninsula was.  So the current average height of Tufe's Turfil sunflowers is undoubtedly at least partially attributable to changes in Tufe's environmental conditions.
 
Which of the following is an assumption on which the argument depends?

In a study conducted in Pennsylvania, servers in various restaurants wrote "Thank you" on randomly selected bills before presenting the bills to their customers.  Tips on these bills were an average of three percentage points higher than tips on bills without the message.  Therefore, if servers in Pennsylvania regularly wrote "Thank you" on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.
 
Which of the following is an assumption on which the argument relies?
错选了C，原文说：在一个研究中，随机选择的顾客看到写有“thank you”的bill，小费会平均高于没有写“thank you”的bill。因此，如果宾州的服务员在bill上习惯性的写上“thank you”的话，他们的平均收入会有显著的提高。不知道原文理解是否正确。问假设。我选的是C，文中的逻辑链是，写“thank you”退出“服务员的收入提高”，ACD感觉有没有回答问题，但是B我确实想不太明白。请老师解答。
