OG11-10. Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.
Which of the following, if true, most seriously undermines the advertisement's argument?
(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.
(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.
(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.
(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor's prescription.
(E) In clinical trials Novex has been found to be more effective than competing brands of painkillers that have been on the market longer than Novex.
答案选C
Three out of four hospitals might be giving their patients Novex not because it is the most effective painkiller for sinus pain, but because it is inexpensive.既然不是因为EFFECTIVE而选择此药，那么为何不能选择B呢？正是因为病人不能忍受一般的药，所以医生开出此种药.
OG11-15 15. A researcher studying drug addicts found that, on average, they tend to manipulate other people a great deal more than nonaddicts do. The researcher concluded that people who frequently manipulate other people are likely to become addicts.

此题没想通OG的解释。我的逻辑是 既然条件people who like to manipulate others _推出_____addict pepole
如果要WEAKEN，则应当从people who DO like to manipulate others---推出-------addict people 或者
people who like to manipulate others ---推出---------non-addict people
我觉得从这两个方面都可以加以削弱
OG11-16. In Swartkans territory, archaeologists discovered charred bone fragments dating back one million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white _ stinkwood, the most common tree around Swartkans.
Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?
(A) The white stinkwood tree is used for building material by the present-day inhabitants of Swartkans. , (B) Forest fires can heat wood to a range of temperatures that occur in campfires.
(C) The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.
(D) Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500,000 years ago.
The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.答案选E
