请教逻辑二道

逻辑10套内，第六套
4.Many people acquire software programs for their home computers by illegally copying those programe rather than purchasing them. People who own home computers must be making, on average, fewer illegal copies of software programs than before, however, since the average number of software programs that people purchase to use on their home computers has
increased substantially over the past five years.

Which of the following, if true, most strengthens the argument?
(A) The number of home computers in use has increased substantially over the past five years.
(B) Five years ago, about half of the software pro- grams used on home computers had been illegally copied rather than purchased.
(C) Most people who have home computers use their computers more frequently the longer they have them.
(D) Few people who prefer to copy computer software programs illegally cannot copy the software programs they want because they have no acquaintances who have those software programs.
(E) On average, people with home computers have the same number of software programs today as people with home computers did five years ago.

我认为应该选D。既然没有了途径做illegal copy,自然这个人数就少了，很符合题干意思啊~~为啥正确答案选E类？虽然E也挺对的~但是D貌似是MOST啊~

11.As people age, the number of calories they need each day decreases while their daily requirement of vitamin B6 increases. Clearly, unless older people take B6 supplements or eat a diet that contains more B6 than did the diet they ate when they were young adults, there is little likelihood that they will get B6 in needed amounts.

Which of the following would be most helpful to know to evaluate the argument?
(A) Whether the relative decrease in the daily requirement of calories is greater than the relative increase in the daily requirement of vitamin B6.
(B) Whether the form of vitamin B6 found in dietary supplements is more readily absorbed and utilized by the body than is the form of this vitamin that
is found in food.
(C) Whether the consequences of not getting vitamin B6 in required daily amounts are more serious for older people than for young adults.
(D) Whether the diets of most people, when they are young adults, include vitamin B6 in amounts far in excess of their daily needs.
(E) Whether the diets of older people are more likely than those of young adults to include one or more meals a day that are devoid of foods containing vitamin B6.

这类题我最怕了~~我选C是因为B6和衰老或者是能量摄入之间的因果关系不能确定啊，只是现象说明增减关系未免太弱了吧？
答案选D,是论证B6的多少有没有副作用，是这个样子咩？
求高手指教
今天狗血了~~555~~11道只对了3道
发现要不就是逻辑关系很难短时间理清、要不就是题干的关键字没有看懂。~~~我的个亲娘啊~！

第一题很显然是E，总量没遍，正版的多了，自然盗版就少了

第二题的D选项不是副作用。如果人们平时饮食中摄入B6过量，那么虽然老了之后需求增加，那也未必需要增加相关食物嘛。所以就D咯

第一题我也选的D。。。也不知道错那
第二道感觉是D，居然对了。我的理解是，现在主题是验证“老年人是不是要通过额外的维他命片或者富含VB6的食物，来获得足够的VB。”D选项，如果年轻时吃的就是过量的，那现在老了怎么补都没有用。因为是吸收不了，不是量不够。所以就需要这么一个本质问题。。说的很混乱，不知楼主看懂没。。。

注意是few people cannot

啊。多谢。看来做逻辑题时候又想当然了。since正版的增加，assumption 总数量没变---->conclusion那盗版的肯定减少。嗯，make sense

楼主能不能烦劳解释一下为啥我的两个选项错类？谢谢谢谢！ 4# 846136085

D选项是“few people cannot”，所以说D选项根本就没有支持原结论，更谈不上most

第四题原文的逻辑是正版增多导致盗版需求减少...D中显然是没有正版增多这个意思的，只是说没了盗版的途径...与原文逻辑最切合显然是E吖...题目不要只看一半....

第十一题其实也很一目了然啊，题目的逻辑认为既然年龄的增加会减少卡路里的摄入需求，增加V B6的摄入需求。所以老年人要吃更多含B6的东西，否则不能满足每日的需求。这里你要明白，前一句话没有说每日的摄入量是正好的....如果本来VB6的摄入量就是过量的呢？所以第一步必须确定正常饮食中每日的VB6摄入量是达不到要求的，如果本来就是过量的，那么后面的命题就是不成立的。而你的C选项与题目相距甚远。题目问的是能不能满足每日的需求，你却回答重不重要。题目问的是量的问题，你回答的确实性质的问题。

我只说gmat，因为这种题gmat里比重很大。多数情况下，most是没有用的，选项里真正可以support的只有一个
