※ 引述《heystranger (卍旷世巨鲁霸气登台卍)》之铭言： : Electric utilities pay less for low-quality coal per ton delivered than for : high-quality coal. Yet more low-quality coalthan high-quality coal must be : burned to generate the same amount of electricity. Moreover, per ton of coal : burned,low-quality coal generates more ash than does high-quality coal, and : the disposal of ash is becoming more and more expensive. : The considerations above, if true, most strongly support which of : the following claims? 不要以为看到support就是加强题～～～ : (A) A coal-burning utility might not be assured of benefiting economically : by always adhering to the policy of keeping its overall coal purchasing : costs as low as possible. : (B) In those regions where the cost of disposing of coal ash is negligible, : it is more expensive for coal-burning utilities to use high-quality : coal than low-quality coal. : (C) Transportation costs represent a smaller proportion of the cost per : delivered ton for low-quality coal than for high-quality coal. : (D) It is no less expensive to dispose of a ton of coal ash that results : from the burning of high-quality coal than it is to dispose of a ton of : coal ash that results from the burning of low-quality coal. : (E) In regions where coal-ash disposal is the least expensive, reserves of : low-quality coal are likely to decline at a faster rate than are : reserves of high-quality coal. : --------------------------------------------------------------------------- : 小弟资质愚钝不解答案为何是A，这题做了快10分钟...超难选择答案最後选了E : 再回过头看A，我的理解A:购买低成本无法保证带来经济利益(不知道这大意对不对) : 可是原文我找不到一个conclusion明确表明low quality就是不实用 : 只有隐性的自己心里认为这个low quality不实用，与其说support，我怎麽觉得这题更 : 像assumption? 请大大指教! 这题不是support也不是assumption，而是推论题。 support跟assumption（以及weaken/evaulation）我们可以视作同一个家族的题型 特色就是：文章中会有一个明显的conclusion 而选项则是新的外来资讯，要去朝conclusion做sup/wkn/assumption/eval 让我们看看常见题干的写法，就知道了： （加强） “Which of the following, if true, most strengthens the argument?” “Which of the following, if true, most strongly supports the statement above?” “Which of the following, if true, does most to justify the conclusion above?” 有没有发现都是下面（following）选项，去朝上面（above）的论点做加强？ 回到今天这个题目，来看看题干： : The considerations above, if true, most strongly support which of : the following claims? 其实是上面（above）的资讯，要朝下面（following）加强， 也就是问你上面的资讯可以推出下面哪个一个资讯。 让我们来看看其他的推论题题干写法： “If the statements above are true, which of the following must be true?” “Which of the following conclusions is best supported by the statements above?” “The statements above, if true, best support which of the following assertions?” “Which of the following can be correctly inferred from the statements above?” “Which of the following is most strongly supported by the information above?” 是不是都是上面（above）朝向下面（following）？所以这其实是推论题。 推论题正好就是问你读完上面所有资讯之後，心中所得到的综合判断。 所以这题你心中的隐姓判断没有错，只是判断题干时错了， 才会避开A不选。 Dustin -- Dustin Deng (一战自修760，AWA 5.5) Dustin/A2GMAT 全科机经班： http://a2gmat.blogspot.tw/p/blog-page.html https://webptt.com/cn.aspx?n=bbs/GMAT/M.1433954252.A.2EC.html GMAT自修资源部落格： http://dustingmat.blogspot.tw A2GMAT线上解题、讨论Group： https://www.facebook.com/groups/A2GMAT --
