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.

Finally reaching a decision on an issue that has long been politically charged
in the Pacific Northwest, politicians decided to postpone by at least five years
an ambitious plan to protect wild salmon and other endangered fish, instead
of which they proposed a series of smaller steps, by which they intend to
protect the fish.
想请问一下，1，这道题的B里面intended是作为adj形式修饰steps吗？如果是动词就变成被动时态了好像不太对？2，我听前面tina老师说这个intend的发出者是steps不是人，可我觉得intend不是一种主观的人发出来的意图嘛？

Among the Tsonga, a Bantu-speaking group of tribes in southeastern Africa, dance teams represent their own chief at the court of each other, providing entertainment in return for food, drink, and lodging.
错选A，请老师指出我思考中的错误，并且讲一讲这道题的正向思考方式，以及being这个用法。我是这样想的：首先根据句意，dance teams应该包括很多team，而B、E中another是两者，所以排出；D选项Being，虽然不知道怎么错…但一般选项有being都不对……所以也排除了；C选项我理解 的句意重点在provide enter上，忽略了后面的as a return on ，所以排除。谢谢老师！！

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolving as a kind of snorkel.
老师，我错选C，请老师指出我做题思维的错误，并讲一讲这道题正确的答题思路。我的思路是这样的：首先，纵向比较句子前办部分，to do 表目的，我认为没有表现出很强的目的的意味，因此排除D、E，其次，我理解trunk originally……是指aquatic of snorkel的，A、B指代不明确，且A句子结构不完整，因此排除A、B。

While most of the earliest known ball courts in Mesoamerica date to 900–400 b.c., waterlogged latex balls found at El Manati and representations of ballplayers painted on ceramics found at San Lorenzo attest to the fact that the Mesoamerican ballgame was well established by the mid-thirteenth century b.c.
