Advertisement: The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee, Inc. So it only stands to reason that if you buy a can of Kreemo's coffee, you're buying the best blended coffee available today.

The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that

几道头疼的逻辑题

The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no companny purchases more Colombian beans than Kreemo Coffee. Inc. So it only stands to reason that if you buy a can of Kreemo's coffee, you are buying he best blended coffee avaiable today.
The reasoning o fthe argument in the advertisement is flawed because it overlooks the possiblility that
A. The equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers.
B. not all of Kreemo's competitors use Colombian coffee beans in the blends of coffee they sell.
C. Kreemo sells more coffee than does any other company.
D. Kreemo's coffee is the most expensive blended coffee available today.
E. the best unblended coffee is better than the best blended coffee.
答案是C,可是我就是想不通为什么。

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 drawbacks, since things would fall off the shelves' edgesinto 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. Refigerators would not be made to have a windowin 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. Refigerators are so well designed that there are bound to be drawbacks to any design change.
E. Rotating helves would be designed to rotateonly the refrigerator door was open.
答案是A,可是为什么呢?

The recent decline in land prices has hurt many institutions that a invested heavily in real estate. Last year, before the decline began, a local college added 2,000 acres to its holdings. The college, however, did not purchase the land but received it as a gift. Therefore the price decline will probably not affect the college.
Which of the following, if true, casts most doubt on the conclusion above?
A. The 2,000 acres that the college was gven last year are located within the sae community as the college itself.
B. The college usually receives more contributions of money than of real estate.
C. Land prices in te region in which the college is located are currently higher than the national average.
D. Last year, the amount that the college allocated to pay for renovations included money it expected to receive by selling some of its land this year.
E. Last year, the college paid no property taxes on land occupied by college buildings but instead paid fees to compensate the local government for servies provided.
答案是D, 寻求解释

第一题个人理解,作者的逻辑是公司K买的Columbia咖啡豆比其他公司多,那么can of Kreemo's coffee就比其他公司的品质好,但忽略了如果K公司卖出去的can特别多,可能平均每个单位里面咖啡豆含量就可能降低了,类似分子分母都很大,分数值就不一定大了。

第二题假设说没法设计适应转架的refrigerated food,所以他们还是可能跌到不被人看到的地方(fall off the shelves' edgesinto the rear corners)

第三题其实把D选项看明白就好了,D主要是说这个大学认为房地产可以出售,预期收益很高,于是花了很多钱,但房产价格下降,实际收益低于预期收益,大学可能就亏空了

说得不对的大家讨论,谢谢

第二题的假设是要表示, Refrigerators 的设计不能避免"things would fall off the shelves' edgesinto the rear corners"这样的情况.大概看来,rotating shelves可能是会有个什么rear corners的部分吧。我个人理解可能是按照一般的冰箱的立方体或长方体的形状,如果在里面加了可以rotate的shelves,应该是会有东西掉到后部的角落里的,搂主可以设想立方体的东西里面有一个圆形的可以转动的架子,那么类似于一个正方形里面有一个内切圆,四个角落肯定是有空的。这样在旋转架子的时候自然会有东西掉到那些角落里了。

而A说Refrigerators would not be made so that their interior space is cylindrical,

把它取非:Refrigerators would be made so that their interior space is cylindrical.就是把冰箱设计成圆柱形的了,也就不存在那个角落的问题,所以也就削弱了文中的反对意见。有这样的取非削弱作用的,就是最好的假设题的选项。

另外,其他的几个选项,搂主仔细看看就会发现它们都是无关的选项。B说有a windowin front for easy viewing of their contents without opening the door,反对意见主要是针对掉东西到角落里的情况,这和可不可以不开冰箱就看到里面的东东无关.C说食物变质问题是不可以通过改进冰箱设计来解决的,这样的一个假设超出了假设的"必要性"范围,如果是SUPPORT题,这样的一个条件是可以当选项的,但是假设题强调必要性,类似于"最大的底限"是什么,没有C如此苛刻的要求.D说的就更离谱了,冰箱设计已经如此的好一直于任何改进都是有drawbacks,无关。E说的是在什么时候可以打开门,这和掉东西到角落里也是无关的。

第三题:D选项说这个学校去年分好的打算今年用来搞翻修的资金包括了他们打算在今年卖掉土地所得的钱,而文中的条件恰好说recent decline in land prices ,地价下降了,这个学校可以得到的钱自然少了,自然就受到影响了啦。直接就削弱了文中的结论probably not affect the college.

不知道我的解释清楚了没?

感谢楼上的MM,太感谢了.第三题已经完全懂了,第二题我不懂得原始是对INTERIOR SPACE 理解不对,我还以为INTERIOR SPACE 是指SHELF.所以答案怎么看怎么不对,但是如果是把冰箱设计成圆柱型的,答案就没问题了.看来阅读问题还是很严重的说.
