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.

In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat.  Having noted the manatee hunters' expert knowledge of manatees' habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.  Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees' survival.
 
Which of the following, if true, raises the most serious doubt about the plan's chance of success?

Twelve years ago and again five years ago, there were extended periods when the Darfir Republic's currency, the pundra, was weak:  its value was unusually low relative to the world's most stable currencies.  Both times a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially.  Now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again.
 
Which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?

Humans get Lyme disease from infected ticks. Ticks get infected by feeding on animals with Lyme disease, but the ease of transmission from host animal to tick varies. With most species of host animal, transmission of Lyme disease to ticks is extremely rare, but white-footed mice are an exception, readily passing Lyme disease to ticks. And white-footed mouse populations greatly expand, becoming the main food source for ticks, in areas where biodiversity is in decline.

The information in the passage most strongly supports which of the following?
我的逻辑思维是这样的: 原文中提到“从大多数的宿主，lyme disease传播到ticks是非常少见的，但是白老鼠是个例外。” 可以断定，没有白老鼠的地方，lyme disease就很少见. 故B正确。 可是C说的是，一个地方如果生物多样性丰富，那么人少得病。可是原文直说了生物多样性“低”的特点 - 白老鼠多导致ticks传染从而导致人得病。可是没说生物多样性“高”的特点，有一种可能性就是生物多样性高，依然有白老鼠，ticks依然传染，人照样生病，所以把C派出了。
