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.

By the same techniques used for genetically enhancing plants, making them disease- or pest-resistant, researchers have been able to increase the amount of protein in potatoes, sweet potatoes, and tobacco.
这道题目我是在语法专项课的jack老师那边看到的；首先jack老师说了几个重要的指代规则1）对应指代，2）就近指代；规则1）对应指代-适用于主从/并列句；从句中代词在主语上，那就指代主句中的主语，从句中代词在宾语上，那就指代主句中的宾语；并且指代必须要符合单复数形式，即it指代单数/不可数；they指代复数；规则2）如果说规则1）这个条件不满足：比如没有主从句/并列句关系，从句中主语代词it无法指代主句中的主语复数，则用就近原则；例如 students like playing soccer, and it ......那么it无法指代students只能指代soccer，满足就近原则； 这道题纠结CD，看D完整性-无法使用对应原则，因为前半句不完整，不满足规则1），则只能用规则2）就近指代-which 修饰plants但是因为makes,则修饰错误；或者说which只能指代techniques(抽象名词也许可以用单数Makes）-我先放着；them指代plants，符合规则2）就近指代; C-so that表目的的连词，则句子有主从关系-规则1）适用，但我先撇下了指代规则，从句子结构来看so that后面句子结构完整-they are disease- or pest-resistant；句子前面的employing the same techniques used to genetically enhance plants，这里不是一个句子used修饰techniques，to enhance表示目的，缺少主语，而主语在后面researchers；因此如果说主句的主语是researchers，so that后面是从句，they are ...they是从句中的主语，应该对应指代主句中的主语researchers，那语义就不对了。可能我用规则把自己绕进去了，jack老师避开了C因为他觉得C是对的没什么好讲的，D的which有指代问题；我感觉C的问题很严重-如果用他的规则

Editorial:  The roof of Northtown Council's equipment-storage building collapsed under the weight of last week's heavy snowfall.  The building was constructed recently and met local building-safety codes in every particular, except that the nails used for attaching roof supports to the building's columns were of a smaller size than the codes specify for this purpose.  Clearly, this collapse exemplifies how even a single, apparently insignificant, departure from safety standards can have severe consequences.
 
Which of the following, if true, most strongly supports the editorial's argument?
问过老师一次但是现在做还是偏差。这道题目我目前最新的认知-exacting翻译为严格的，less exacting我方便一点翻译为宽松的；A说了标准宽松导致了坍塌；（这里标准比较宽松和没有达到一个宽松的标准应该有区别,感觉还是无关）；题干结论说：departure from safety standards can have severe consequence-没有达标会导致坍塌；这俩个没有说一个事情吧；宽松的规则会坍塌；没有达到严格的标准会坍塌；我总觉得中间差距很大；我第一次做选E；当时觉得没法选出来一个正确的,所以勉强选了E ;当时我想到的是严格的标准，是否需要很多条件匹配-比如房子不能太空…我不想钻牛角尖，但是我感觉我还是走偏了…
