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.

Which of following most logically completes the argument?
 
The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago.  Prehistoric cave paintings in France depict this animal as having a large hump on its back.  Fossils of this animal, however, do not show any hump.  Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______.
请唐老师解答，谢谢，这题我只看了nevertheless后面部分（然后选的A），意思是没理由去推测洞穴绘画是不正确的，然后看选项B有比较所以无关，D的时间也无关，剩下ACE感觉根据最后一句无法判断了，是不是还得把带however的上一句也读了？根据化石没有显示hump所以选C？

请问张慧雯老师，本题为什么B不对？ Resource-based theory offers an answer, asserting that, in general, firms gain competitive advantages by accumulating resources that are economically valuable, relatively scarce, and not easily replicated. A相反对应的是relatively scarce,那原题问的是inability就是对原文这几个词取相反的意思，那为什么B不对呢？

If the units digit of the three-digit positive integer k  is nonzero, what is the tens digit of k ?
(1)       The tens digit of k + 9 is 3.
(2)       The tens digit of k + 4 is 2.
请问徐小梅老师，本题还是有点晕，想请您再把两个条件都讲讲。问题1：k的十位数+9=3，任何一个小于等于9的数加9肯定要进位所以可以确定这里的十位数是4吗？问题2：还是不是很明白条件2，翻译出k的十位上的数+4=2，我觉得k只能等于8啊，因为如果不进位的话k岂不是=-2不符合题目的背景信息，所以想请老师讲解这两个问题。

Editorial in Krenlandian Newspaper:
 
Krenland's steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties.  But whatever the cause, the cost is ultimately going to be jobs in Krenland's steel industry.  Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
 
Which of the following, if true, most seriously weakens the editorial's argument?
请问张慧雯老师，逻辑链：P（条件）：低价进口影响了K国钢铁企业的销售量，进而影响钢铁行业就业 C（结果）：减少低价进口不仅能保护K国钢铁企业还能保护K国工业就业。E: K国钢铁工人的工资与出国口工人工资差异很大。这里的错误是不是在于他只说了差异大，但是哪里工资高哪里工资低我们不知道，如果K国工资比国外还高一点呢？所以E选项不选。本题c选项： K国很多面临严峻国内国际竞争的制造商，钢材在其原材料成本中占据非常大的比重。那这个选项和是否限制进口有什么关系呢？谈的是原材料比例的问题，有点绕不过来，然后请老师看看我E选项排除的原因对不对。

Which of the following, if true, would most weaken Krech's objections to Martin's theory?
请问张慧雯老师，本题可以理解B选项，对C选项还有疑问，Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene. 克雷奇还反驳了马丁将气候变化排除在外的解释他断言世纪末确实发生了大范围的气候变化。C选项其他证据表明，大范围的气候变化不仅发生在更新世末期，而且发生在以前和以后的时代，这里是不是变相支持了K的反对，但是问题问的是削弱K的反对。

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was 10 years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
请问张慧雯老师，本题逻辑链：p：现在孩子玩雪橇受伤的概率比十年前增加了，现在都用塑料雪橇 c：塑料雪橇更加危险，然后我就选了b，理解是很少有孩子在玩雪橇时穿戴任何类型的防护装备，比如头盔。那就是说是因为孩子自身的原因导致危险增加，和塑料雪橇本身没有关系，为什么B是错误的呢？
