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.

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.

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.

A mutual fund having billions of dollars in assets will typically invest that money in hundreds of companies, rarely holding more than one percent of the shares of any particular corporation.
请问Tina老师，A选项和D选项如何察觉出正误。我认为A选项虽简洁但holding是存在歧义，不易马上知道hold 的主语；而D选项用they来代指companies很直接明白，且so that的因果关系也可以理解成立。请问该如何确认呢？

Found only in the Western Hemisphere and surviving through extremes of climate, hummingbirds’ range extends from Alaska to Tierra del Fuego, from sea-level rain forests to the edges of Andean snowfields and ice fields at altitudes of 15,000 feet.
请问Tina老师，B和E俩选项都可以理解，我觉得都没有硬伤。说B有不足（extending对前句中的survive并没有解释说明，不是解释说明其如何survive），能够convinced；说E不足（并列关系中主语有变化导致不连贯），也能够convinced。 inthiscase在考试中如何确定出来？还是错一个就错一个？

Newspaper editorial:
 
In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor's ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.

The information in the passage suggests that which of the following statements from hypothetical sociological studies of change in industry most clearly exemplifies the social constructivists’ version of technological determinism?
这题研究了很久不是很懂怎么做。大概觉得是原文 The alternative to constructivism, in other words, is to view technology as existing outside society, capable of directly influencing skills and work organization找答案。技术实在社会外，直接影响skill和work organization。所以大概选A？但A有个rather than，好像原文也没有。所以不怎么敢选。 我选的时候，选的是b。来源于原文Technological change is construed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. This position represents the new mainstream called social constructivism.所以b差不多就是social constructivist的观点。但是，题目问的是，social constructivist对于技术决定论的看法，而不是social construtism本身的观点。因此b不对。因此答案要从misrepresenting的那段找。 是这么思考么？请老师解答。
