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.

D

People who do regular volunteer work tend to live longer, on average, than people who do not. It has been found that “doing good,” a category that certainly includes volunteer work, releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. Clearly, there is a connection: Regular releases of endorphins must in some way help to extend people’s lives.

Which of the following, if true, most seriously undermines the force of the evidence given as support for the hypothesis that endorphins promote longevity?

The tulu, a popular ornamental plant, does not reproduce naturally, and is only bred and sold by specialized horticultural companies. Unfortunately, the tulu is easily devastated by a contagious fungal rot. The government ministry plans to reassure worried gardeners by requiring all tulu plants to be tested for fungal rot before being sold. However, infected plants less than 30 weeks old have generally not built up enough fungal rot in their systems to be detected reliably. And many tulu plants are sold before they are 24 weeks old.

Which of the following, if performed by the government ministry, could logically be expected to overcome the problem with their plan to test for the fungal rot?

Healthy lungs produce a natural antibiotic that protects them from infection by routinely killing harmful bacteria on airway surfaces.  People with cystic fibrosis, however, are unable to fight off such bacteria, even though their lungs produce normal amounts of the antibiotic.  The fluid on airway surfaces in the lungs of people with cystic fibrosis has an abnormally high salt concentration; accordingly, scientists hypothesize that the high salt concentration is what makes the antibiotic ineffective.
 
Which of the following, if true, most strongly supports the scientists' hypothesis?
老师这道题梗还是没理解。原文说 健康的肺能产生自然抗生素去杀死病毒，但纤维化的肺就无法杀菌。往往受感染的纤维化肺部检验出高浓度的盐，所以科学家得出结论，高盐度是肺无法正常抗菌的原因。问题支持该假设。所以就是补充-就是盐分导致肺ineffective。A说 故意增高健康人肺部盐分，盐浓度会回到标准水平--加盐后健康肺的反应，无法说明高浓度就是导致纤维化肺部无效。B一些样本显示低浓度盐分里的抗生素也能杀菌，这个无法对高浓度怎样形成支持。杀。C纤维化肺部的组织被控制盐浓度在一定范围就还是可以抗菌的，先放一边。D很多肺病可以用和横抗生素治疗，完全跑题，杀。E高盐度在很多情况下都存在，没有任何语义贡献，杀。所以虽然C梗没读出来也出来了答案。您看我这么推可以吗？是否有更好的方式，也请您给出合理推论的过程。谢谢！

The primary purpose of the passage is to
老师，这题大致逻辑是读出来：第一段 isconventional galaxy之外新发现了dim galaxy，讲了这个新发现是什么。第二段may回答（也就是一种猜想也不是已经解答了）一个puzzle，就是可能会解答那些missing mass。B这个物质是星星的源，所以从星星发光程度可以估计出B的量。however，氦元素含量表明真实存在的B的量远比肉眼观察估计出来的量要大得多。天文学家推测一定会在银河系某处能看到missing mass的。这道主旨题错选了E。inconsistency我定位到“宇宙中B本来挺多的但是实际没观测到”这里了。请老师逐一杀一下选项，尤其是我为什么错怎么避免这类题容易混淆主旨。谢谢

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a droip in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.
 
Which of the following is an assumption on which the argument depends?
这道题其实做过好几次了，听过老师讲解没有特别琢磨就是杀掉了肯定离谱的，留下了C。原文说：Bo降低关税，但是在Bo的电视销量没变。但是，近期，Bo的装配工人数量少了。所以Bo从V进口的电视数量上升了。题干问能推出电视进口量增多这个结论依据的假设是： A， V的装配工人数量大增，弥补了bO的工人减少数量。上面结论就是，进口的电视数量增多了，这个选项跟电视数量增多没关系。 B，电视特点，没关系。C,，Bo的装配工人花费的平均每台装配时间没有特别大幅度的decrease，（没有更少的时间去装配，也就是每个工人装配一台电视花费的时间，没变或者还增加了hours，都是可能的情况--所以可以得出，工作效率没有上升啊。。虽然读到这里还是觉得逻辑很扭曲，但是放着吧） D 电视装配数量，每年在V的，迅猛增加了—增加不增加，跟导致Bo从V进口数量上升没有因果关系。E，工人工资的减少比较，不是导致电视进口数量的原因，无法弥补原文逻辑。但现在又想了一下，真的觉得很诡异。。Bo的工人数量少了，而且每个工人的工作效率还没变或者更低（因为装配每台的hours没有减少啊），怎么就证明还能装配更多的甚至来自于V进口的电视呢。。。虽然可以用排除法做，但是我还是苦于没有明白这里的梗在哪。也听了英吉老师讲过的一个思路，一看原文的开头hourly wages，那只有C说了average hours，所以就这个相关。。。我觉得这个还是很牵强的眼神定位吧。如果再有个迷糊的，没法这么做的。请老师解惑
