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.

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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Lyme disease is caused by a bacterium transmitted to humans by deer ticks.  Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice.  However, certain other species on which the larvae feed do not harbor the bacterium.  Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium―and hence the number of people contracting Lyme disease—would likely decline.
 
Which of the following, if true, most strengthens the argument?癮
老师好，我可以理解用答疑里说的“概率”来解释，但是考试时候我感觉很难想到这一点。我认为，这道题的解释应该是C里的only once根本就不需要管，只要C说deer tick feeds on....while in the larval stage就够了，就算他是feed一百次一千次都无所谓，因为他只要feed on就能strengthen。就像英吉老师讲的北京喝雪碧，什么什么红毛猴子产雪碧说明北京有喝雪碧的可能，这个例子一样，只要能跟他相关，是postive的答案就可以，对吗？请教
