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.

Political Advertisement:
 
Mayor Delmont's critics complain about the jobs that were lost in the city under Delmont's leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont's tenure the average paycheck in this city has been getting steadily bigger.
 
Which of the following, if true, most strengthens the argument in the advertisement?
请老师再讲一下AD的区别 我当初听英老师讲A觉得没问题，但现在一看意思好像又晕了。原文是想让夸MD做得很好。A说的是过去三年平均公司比M D早期任职是要高，这不是贬低MD啊，这是在他当政期间平均工资高了，为啥不选？ D说的是消掉的工作平均工资跟市内平均工资一样，这倒很无关。请老师指点，谢谢啦！

4. For each of the following sponsors, select Yes if an attendee of the sponsor’s conference would spend less money by employing the ROHH strategy—paying the lowest possible room rate outside the host hotel and paying the nondiscounted registration fee—than by reserving a room in the block at the host hotel. Otherwise, select NO.
姜老师好， IR的思路我还是不太灵光的，比如： 1， 题目文字过多，如何快速摘出关键信息，同时避免丢失隐藏的关键信息。如酒店这道题1，reserving a room in the block的房费计算方法如果根据原文的话就很绕，是根据原文大致提到了discount，所以对应table中去提炼信息为discounted registration fee。但我自己做时，没有有效联系文章三段与给出的table去建立公式，就很晕 2， 住酒店这道题的2，因为第一问已经运用了公式计算房费是涉及到registration fee的，第二问为计算时不考虑registration fee?是因为如果空房，就不用registration fee了对么？这个信息是常识（真的不知道这个逻辑，平时国内好像没怎么仔细想过这个问题）还是从文章中能得到的信息？ 3， 还是酒店这道题目的第3问，题目对应的是原文第三段，站在block的角度去说；cost-saving strategy，计算差价的时候，都不用分别加上registration fee再去比较么？ 4，酒店这题的第4问，还是对应信息的问题。题目让求ROHH的战略跟block比是否省钱，ROHH计算方法给了，lowest possible room rate OUTSIDE the host hotel,原文的table中 没有对应的值，原文中是在最下面一行字提到了lowest rate for an available room in City X …is $65. 说实在的，我自己做题时，很难把描述不一致（或者眼神看来不是很一样）的信息对应到一起，也就是胆小、不踏实不敢乱对应信息，这道题如果读不出来这里文章最后一行的65块钱就是第四题里面定义ROHH房价公式的最低rate，就做不出来了。 超级感谢姜老师！期待您的指点

Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made only unleavened bread, such yeasts must frequently have been mixed into bread doughs accidentally.  The Egyptians, however, did not discover leavened bread until about 3000 B.C.  That discovery roughly coincided with the introduction of a wheat variety that was preferable to previous varieties because its edible kernel could be removed from the husk without first toasting the grain.

The first trenches that were cut into a 500-acre site at Tell Hamoukar, Syria, have yielded strong evidence for centrally administered complex societies in northern regions of the Middle East that were arising simultaneously with but independently of the more celebrated city-states of southern Mesopotamia, in what is now southern Iraq.
这题 有点选不出来。 不知道为什么 要直接用 cut 而不是 that were cut。 然后 为什么是 have yield 而不是 yields 并且 为什么是 with but 而不是 but also？
