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.

In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to proteins on its surface.  Mice infected with a herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye.  Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies to herpesvirus.
 
Which of the following, if true, gives the greatest additional support to the scientists' hypothesis?
原文实在读得太晕了,就读出来大概是老鼠感染病毒免疫系统会产生抗体,通过联合蛋白质什么的,反正就是说免疫系统的反应,然后又说老鼠感染眼病会产生k这个物质,发现眼睛细胞上的蛋白质和h表面的相似,所以假设K是由h抗体引起的,让支持,因为完全没明白什么意思觉得肯定和k相关留下CDE,觉得E好像方向错了,CD之间无法取舍就选了C,请老师讲一下

Traveler:  Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents.  Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight.
 
Which of the following, if true, casts the most serious doubt on the traveler's argument?
我选的E,虽然SA的事故频率很高,但是两个航线在航班中的事故比率仍然非常低。我这是否属于选项发散,因我把airlines发散成了from Pederton to Dacenta的航线。 review的时候,看到B,大多数的SA航班,但不包括从P到D这条线的航班,使用S这个机场,这个机场因为处于多山所以是世界上最危险的地方之一。这是把其他出口打开,将原文SA本身发生事故的可能性降低。 但是在考场上根本想不到这么多啊~

Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.  However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual.  Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies' finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.

The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer.  That assumption, however, is evidently false:  in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.
