标题: 求助两道逻辑题---很简单，只是我实在想不通~~~
GWD-24-29.
Plant scientists have been able to geneticallyengineer vegetable seedsto producecrops that are highly resistant to insect damage. Although these seeds currently cost more than conventionalseeds, their cost is likely to decline. Moreover, farmers planting them can usefar less pesticide, and most consumers prefer vegetables grown with lesspesticide, therefore, for crops forwhich these seeds can be developed, their use is likely to become the norm.
Which of the following would be most useful to knowin evaluating the argument above?
A. Whether plant scientists have developed insect-resistantseeds for every crop that iscurrently grown commercially
B. Whether farmers typically use agricultural pesticides inlarger amounts than is necessaryto prevent crop damage.
C. Whether plants grown from the new genetically engineeredseeds can be kept completelyfree of insect damage.
D. Whether seeds genetically engineered to produceinsect-resistant crops generatesignificantly lower per acre crop yields than do currently used seeds.
E. Whether most varieties of crops currently growncommercially have greater natural resistanceto insect damage than did similar varieties in the past.
这道题之前有讨论过啦，可是大家都在纠结B和D，我纠结的却是A和D，A中如果没有给每个植物都有这样的种子，那么这种种子还是不会become the norm，削弱了原文，可是。。。为什么不对呢？

93. (24269-!-item-!-188;#058&000870) (GWD-21-Q38)
Becauseit was long thought that few people would watch lengthy televised politicalmessages, most televised political advertisements, like commercialadvertisements, took the form of short messages. Last year, however, one candidate produced ahalf-hour-long advertisement. At thebeginning of the half-hour slot a substantial portion of the viewing public hadtuned in to that station. Clearly, then,many more people are interested in lengthy televised political messages thanwas previously thought.
Whichof the following, if true, most seriously weakens the argument?

A.The candidate who produced the half-hour-long advertisement did not winelection at the polls.
B.The half-hour-long advertisement was widely publicized before it was broadcast.
C.The half-hour-long advertisement was aired during a time slot normally taken byone of the most popular prime-time shows.
D.Most short political advertisements are aired during a wide range of programsin order to reach a broad spectrum of viewers.
E.In general a regular-length television program that features debate aboutcurrent political issues depends for its appeal on the personal qualities ofthe program's moderator.
这道题的D我怎么觉得也挺有道理的啊，因为这个political的广告到处都在播，那么人们没有办法只好看这个了，所以好像显得人们都很关注政治新闻一样，其实并没有，这样不也削弱了原文了吗？

每次都靠第一感觉做出来，可是认真想想就怎么都想不通了。。。上了考场完全没有了第一感觉，什么都不会了喔~~~~~~~~~

这是第二题的结论

那么D说Most short political advertisements跟结论有关么？无关选项怎么weaken啊第一个就应该排除掉

拜托，还是有点不明白啊，short political advertisements不是和political message挺相关的吗？为什么无关的啊

第一题：
目的：降低成本
手段：播种新种子
评价：是否能够真的降低成本

B确实有争议。但是A起不到评价的作用。
就比如说，现在有一种记忆改良，种出来的新型的胡萝卜吃了能减肥，而人们都喜欢吃能减肥的食物，所以这种胡萝卜会成为一种热销品。那么来评价设个结论，你说，是不是每一种萝卜都能变成减肥萝卜呢？这跟我这个胡萝卜卖的好不好无关啊~~~

every crop就算是引入的新元素了

题干中的转折词可以成为你选择结论的提示。
这个题的思路是：科学家balabala。虽然balaba。但是！！！！更何况balabala。所以balabal。
按照语言习惯来说，但是后面才是重点。所以个人喜欢D胜过B

题目在对比长的广告和短的广告啊

通俗点说。
通常人们都喜欢吃小包子，可是最近开了家包子店，发现他家的大包子销量更好，所以人们通常的认识是错误的。
削弱。你说小包子因为携带容易所以广受欢迎。

这不能削弱结论说大包子才受欢迎啊。

所以正解应该是其实不是大包子受欢迎，是因为买一个大包子就会送一袋一直很畅销的豆浆。
这样明白了么？
