大全-16-2.   The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would have just the same sort of drawback, since things would fall off the shelves’ edges into the rear corners.
Which of the following is presupposed in the argument against introducing rotating shelves?
(A) Refrigerators would not be made so that their interior space is cylindrical.
(B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.
(C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.
(D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.
(E) Rotating shelves would be designed to rotate only while the refrigerator door was open.
这题我选的是D，答案是A，谁能解释一下这A和题干的逻辑关系？

一次问一道太不划算了，容我再问一道~！
大全-15-6.   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 more effective than competing brands of painkillers that have been on the market longer than Novex.
这道题答案是D，我选的是C

再来一道不嫌多啊~
大全-16-15.   In the course of her researches, a historian recently found two documents mentioning the same person, Erich Schnitzler. One, dated May 3, 1739, is a record of Schnitzler’s arrest for peddling without a license. The second, undated, is a statement by Schnitzler asserting that he has been peddling off and on for 20 years.
The facts above best support which of the following conclusions?
(A) Schnitzler started peddling around 1719.
(B) Schnitzler was arrested repeatedly for peddling.
(C) The undated document was written before 1765.
(D) The arrest record was written after the undated document.
(E) The arrest record provides better evidence that Schnitzler peddled than does the undated document.
我选的A，显然是我无奈之下的选择，但我就不知道C为什么是对的。。。
同志们开动脑筋吧~thanks again！

第一题，cylindrical圆柱体的，不就没rear corner了嘛，所以这是个好的presumption

第二题，c选项只说明了医院购进药的环节并不直接影响他卖药的环节，除非他说这种药的利润率更高之类的

谢谢同志们~但是第二题的D选项又为什么对呢？在我看来如果某种药的药价被压到最低，医院会愿意尽量向患者推荐那种药因为这样相对于其他以一般价进货的药会有更大的利润。。。

第二题：D:If Novex is nonprescription,the patient can get it easy.
第三题：If there is a paradox between the record and the statement,we can contradict the conclusion.In order to defend the conclusion,we can decrease the chance of paradox's happening

对了，这个pharmacy是指医院开的药方吗？drug store才是普通的药店？
我觉得第三道题里的第二个document是发生在第一个之前的，所以如果第二个是发生在1735-1765之间那不还是paradox吗？

第二题：觉得C还是不懂。。。那个增强了argument
第题 D为什么不对呢？

dengts · 发表于 2011-4-9 22:57:42

pharmacy=drug store
不得不用汉语了。。。。第二个document明显发生在第一个之后。。。。想象一下：这个哥肯定是第一次被抓才有第一个记录。。。。。第二个是文件已经说明这个哥是惯犯了。。。。。最好的的是第二个发生在晚于1739早于1739+20=1759这段时间，但是这是一道support题.Speaking in numerical terms,any answer choice that strengthen the argument,whether by 1% or by 100%,is correct.Complement set of {晚于1739到早于1759} is{早于1739或晚于1759}.C:{早于1765}decreases the CHANCE of paradox's happening,correct.
