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

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.

Manatees, aquatic mammals inhabiting Florida's rivers and coastal waters, swim close to the surface and are frequently killed in collisions with boats.  To address the problem, boat traffic in manatee-populated waters is being required to maintain very low speeds.  Unfortunately, manatees are unable to hear low-pitched sounds and a boat's sound lowers in pitch as the boat slows.  Therefore, this approach may in fact make things worse rather than better.
 
Which of the following, if true, casts most doubt on the conclusion?
比较BE B说的是m吃的wh这种东西的bed会被快速的船破坏，我觉得B沾边,像那种前面不沾后面沾的感觉。 E说的是m能不能分辨不同速度的声音，我排除这个选项有两个原因，一个是原文说的是m能不能听到low-pitched的声音，我觉得听到和分辨不是一回事，第二就是这个选项中拿来做实验的m和原文第一句话说的住在Florida's river的m不一定是同一些m，范围不准，所以我就选了B。

Until a few centuries ago, any large bones discovered in the fields or caves of Europe, now known to be large prehistoric animals, were usually assumed to be the remains of giants and were often displayed as curiosities in castles, palaces, town halls, churches, and monasteries.
我选了B 看选项时首先发现开头有没有bone，我觉得前面说了一些bone被发现在哪，而修饰的对象并没有变化，所以我认为再说一次bone有点罗嗦，（录音里说这里不加bone的话会有歧义，不清楚known短语修饰的是谁，我体会不到这里为什么会有歧义）于是我排除了CD 剩下的选项我发现known as known to be 还有assumed as assumed to be的区别，我觉得to be有将来的意思，而这里并没有之前之后的概念，而且划线外and后面与之并列的display也跟的as，于是我就选了B
