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.

Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite.  Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.
 
Which of the following, if true, most seriously undermines the argument?
想选择B。对题目的理解是因为实验室合成条件严苛所以自然界中也能形成的F物质让科学家想要去研究地球crust的情况。选B的原因是这个物质是也在meteorite上发现，那么found in nature的那些也可能来自外太空（就没必要去检测crust了，因为不在地球上形成）不选D的原因是科学家已经准备检测crust了，不就是默认这个东西是在crust附近形成？（那个structure也可能只是crust的一部分吧）还是说因为是一个未知的structure所以weaken了检测crust的必要？这个题做错了反映的是什么样的思维误区呢？谢谢老师

Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.  One plan to accomplish this is to establish giant floating seaweed farms in the oceans.  When the seaweed plants die, they will be disposed of by being burned for fuel.
 
Which of the following, if true, would indicate the most serious weakness in the plan above?
答案选正确了，但是在做题过程中犹豫过A。感觉A是建这个plan的前提（plan是否存在），B是判断plan有没有用。所以weaken的时候都是默认这个plan一定存在么？谢谢老师！
