6. In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?(C)

A. A few children still use traditional wooden sleds.

B. Very few children wear any kind of protective gear, such as helmets, while sledding.

C. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.

D. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.

E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

9. 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.(D)

The argument above requires which of following assumptions?

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.

13. A sudden increase in the production of elephant ivory artifacts on the Mediterranean coast of North Africa occurred in the tenth century. Historians explain this increase as the result of an area opening up as a new source of ivory and argue on this basis that the important medieval trade between North Africa and East Africa began at this period.

Each of following, if true, provides some support for the historians’ account described above EXCEPTD)

A. In East Africa gold coins from Mediterranean North Africa have been found at a tenth-century site but at no earlier sites.

B. The many surviving letters of pre-tenth-century North African merchants include no mention of business transactions involving East Africa.

C. Excavations in East Africa reveal a tenth-century change in architectural style to reflect North African patterns.

D. Documents from Mediterranean Europe and North Africa that date back earlier than the tenth century show knowledge of East African animals.

E. East African carvings in a style characteristic of the tenth century depict seagoing vessels very different from those used by local sailors but of a type common in the Mediterranean.

14. In January of last year the Moviemania chain of moive theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Moviemania's own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.

Which of the following, if true, most strongly supports the argument against Moviemania's claim?(A)

A. Total sales of all refreshments at Moviemania's movie theaters increased by less than 5 percent last year.

B. Moviemania makes more money on food and beverages sold at its theaters than it does on sales of moive tickets.

C. Moivemania's customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.

D. Total attendance at Moivemania's movie theaters was more than 20 percent bigger last year than the year before.

E. The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.

建议你一道一道的问好么？否则大家看到这么多的问题，头先晕了。

第一题，小安没给准确的答案，我倾向于c，因为这个选项指出了他因，即并非是因为它不安全，而是因为它使用多。但估计这道题以后再没人碰到过，因为此后的机警无人提及。
