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.

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging, which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.
请问老师，这里的正确答案B加上划线外的，or surface fires that burn down individual trees but do not denude the forest ， 这里一个定语从句，后面俩个并列句子修饰同一个先行词，为什么but后面没有that呢？请帮忙解答，谢谢老师！

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.
E为each one of which dates; have done;要先于主句的动词发生；我想确认一下，这句话的意思是说A和H是俩个幸存最久的communities，我当初选A是因为dating back…这个是进一步解释，伴随状态；而老师说have done不行，因为要先于主句动词发生，那语义上先后顺序可以理解为-因为他们先存活了1000年/他们的communities至少可以追溯到1000年以前；所以他们是最古老的（这个结论后面才能发生）,或者说作者给出了的这个结论是根据时间来的, 结论是后面才能提出的。这样理解不对吗？

The steel industry has changed radically over the last two decades, as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one end of the process to shipping at the other have greatly downsized, or in some cases shut down altogether.
A中as解释为像，比如，是介词，后面跟一个名词，such as也是介词，后面跟名词，则A排除；保留B；C选项with没有紧跟句子，结构上可以保留，with可以表示伴随，也可以表示解释，语义上with后面的东西用来解释radically changed，保留；while翻译为尽管，是连词；翻译为当，也是连词；则D只有名词+修饰语，缺少动词；E明显不对，因为有从属关系-举例/解释被解释；保留了BC；对比BC，B 中as作为副词-翻译为比如；such as也是比如一句话中能出现连续俩个这样的吗？如果说the steel industry has changed radically over the last two decades, such as large integrated company, Bethlehem Steel不是更好吗？

During her presidency of the short-lived Woman's State Temperance Society (1852-1853), Elizabeth Cady Stanton, as she was a staunch advocate of liberalized divorce laws, scandalized many of her most ardent supporters in her suggestion that drunkenness should be made sufficient cause for divorce.
我现在认为a staunch advocate可以作为同位语，则E中的she多余；这道题的考点是同位语其实更好，但是另一种理解是否有偏差？as等同于because，表示因为，后面接一个完整的句子；Elizabeth scandalized many blabla, as (because) she was a advocate；另外老师说suggest that sb.+动词原形，那suggestion that sb.+动词原形对吗？或者说更通俗的是suggest that somebody (should) do sth. Should可以省略，但动词需要原型；suggestion that somebody (should) do sth. Should可以省略，但动词也需要原型；

Neuroscientist: Memory evolved to help animals react appropriately to situations they encounter by drawing on the past experience of similar situations. But this does not require that animals perfectly recall every detail of all their experiences. Instead, to function well, memory should generalize from past experiences that are similar to the current one.

The neuroscientist’s statements, if true, most strongly support which of the following conclusions?
a选项错误的原因我有点拿不准，原文说原文说记忆帮助动物反应，并不是要求记住动物记住每个细节。这个和是否有动物记住细节没有关系对么？
