GMAT逻辑实例讲解（GWD13 Q15,Q17,Q18）.

　　相信大家对于GMAT 逻辑都存在不小的疑虑，而GMAT 逻辑实例讲解资料只有官方的OG，为此澳际小编特将GWD中的CR部分提取出来，进行实例讲解，分享给大家，希望对大家有所帮助，观点仅代表个人，仅供参考。

　　GWD-1-Q15:

　　In parts of South America, vitamin-A diciency is a serious health problem, especially among children. In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A. The plan has good chances of success, since sweet potato is a staple主要成份 of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene.

　　Which of the following, if true, most strongly supports the prediction that the plan will succeed?

　　Which of the following, if true, most strongly supports the prediction that the plan will succeed?

　　Which of the following, if true, most strongly supports the prediction that the plan will succeed?

　　The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.

　　The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat different when prepared from SPK004.

　　There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.

　　The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.

　　There are other vegetables currently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.

　　GWD-1-Q17:

　　The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therore hypothesize that the diatonic musical scale was developed and used thousands of years bore it was adopted by Western musicians.

　　Which of the following, if true, most strongly supports the hypothesis?

　　Which of the following, if true, most strongly supports the hypothesis?

　　Which of the following, if true, most strongly supports the hypothesis?

　　Bone flutes were probably the only musical instrument made by Neanderthals.

　　No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.

　　The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.

　　Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.

　　The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.

　　这个笛子只有四个孔残留，而结论认为这个四孔的骨笛就表明了当时就是7音音阶，则实际上是假定这个骨笛当时应该是至少有7孔的，e支持了这个假设。

　　GWD-1-Q18:

　　It is illegal to advertise prescription medications in Hedland except in professional medical journals or by mail directly to physicians. A proposed law would allow general advertising of prescription medications. Opponents object that, in general, laypersons lack the specialized knowledge to evaluate such advertisements and might ask their physicians for inappropriate medications. But since physicians have the final say as to whether to prescribe a medication for a patient, the objection provides no grounds for concern.

　　Which of the following would it be most usul to establish in order to evaluate the argument?

　　Which of the following would it be most usul to establish in order to evaluate the argument?

　　Which of the following would it be most usul to establish in order to evaluate the argument?

　　Whether nonprescription medications can interact with and block the action of any prescription medications that could be advertised to the general public

　　Whether most prescription medication advertisements directed at the general public would be advertisements for recently developed medications newly available by prescription

　　Whether prescription medication advertisements directed at the general public would appear on television and radio as well as in print

　　Whether physicians are more likely to pay attention to advertising directed to the general public than to advertising directed to physicians

　　Whether physicians are likely to succumb to pressure from patients to prescribe inappropriate medications

　　A与非处方药无关，B的newly available，C的广播电视广告无关。D医生是否更注意直接给医生的广告还是登在公众出版物上无关。题目中含有患者找医生开药，选项中应该有“医生是否会给开”这样的意思。
