107. Last year all refuse collected by Shelbyville city services wasincinerated. This incineration generated a large quantity of residualash. In order to reduce the amount of residual ash Shelbyvillegenerates this year to half of last year’s total, the city has revampedits collection program. This year city services will separate forrecycling enough refuse to reduce the number of truckloads of refuse tobe incinerated to half of last year’s number.

Which of the following is required for the revamped collection program to achieve its aim?

(A) This year, no materials that city services could separate for recycling will be incinerated.
(B) Separating recyclable materials from materials to be incineratedwill cost Shelbyville less than half what it cost last year to disposeof the residual ash.
(C) Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year.
(D) The refuse incinerated this year will generate no more residual ashper truckload incinerated than did the refuse incinerated last year.
(E) The total quantity of refuse collected by Shelbyville city servicesthis year will be no greater than that collected last year.
















答案




先自我分析一下： 结论：下划线部分（residual ash减半）
                            前提： revamp  its collection program:  黑体部分 （即， number of truckloads of refuse减半）


                            题中潜在的前提是：refuse的truckloads减半 就能推出 residual ash也减半。


                           推理漏洞是：recycling那部分的refuse能产出的ash是多少呢？




啊啊啊啊啊啊啊啊啊！！！！！！！！！！！！真想咆哮！！！！！！！！！！


尼玛D劳资仔细想想也能想明白！！！！！！！！！！！！为毛想起来着么费劲呢。。。！亲，告诉我肿么办5555555好想哭啊。。。。我想明白要这么久~！！！！！！！！！》。。。


谁能在给我解释一下，这道题啊。。
我一开始选E..

City service will separte enough refuse for recycling purposes in order to reduce the total number of truckloads of refuse sent for inceineration by half.  The intent is to convert at least half of the refuse for recycling in order to cut the total amount for incineration/burning in a year.

If you read carefully, you would notice a scope shift from "the amount of residual ash" to "the number of truck loads." For the conclusion to hold, D has to be true, since it connects "amount of ash" to "truckload."

刚弄懂的一题

从别人处看来的，牛人的解释很精辟

总量(the amount of residual ash)=the number of turckload * residual per truckloads

也就是：

总量减少  需要：

1. 拉去倒垃圾的车次减少            (去年100趟，今年50趟)
2.每辆车的垃圾烧出来的垃圾灰不能去去年多     (因为即使车次少了，你每辆车拉的多了，也会多)

一共产生多少垃圾灰=拉了多少趟车*一趟车产生的垃圾灰

不知道说清楚没

Could you further explain og's explanation of option A please? I could't understand its explanation.


"This merely indicates that no further reduction of ash through recyclingcould be achieved this year; it indicates nothing about how much the ash willbe reduced."


Option A: This year, no materials that city services could separate for recycling will be incinerated.


And option C's og explanation as well:
"Since no information is provided about how much, if any, recyclablematerials were removed from the refuse last year, this does not a?ect the reasoning."


Isn't it clear that no recyclable materials were removed from the refuse last year as inferred from "Last year all refuse collected...was incinerated"? Then why does the explanation mention "since no information is provided about how much, if any, recyclable materials were removed from the refuse last year"?  


Option C: Refuse collected by city services will contain a larger proportion ofrecyclable materials this year than it did last year.


Thank you!

我是来安慰的 ~~~~~~~~

他们说逻辑题要一分半一个，我两份钟了......题目还没看懂.......
我觉得我就是白痴阿..............!!!!!!!!!!!!!!!!!  


100后，本白痴的错误率也上升了

表示100以后确实感觉不一样。。

我也是，到100以后就错的多了。。。

这里明白了

这题这样想就简单了，
题目说的是：要用回收垃圾来减少垃圾灰，“回收垃圾”是一个事实，事实承认即可，不需要再去解释或者证明，所以只需证明“垃圾灰减少”就行了。
C选项在解释一个事实，所以无用。
D选项，因为5个答案中只有D说的是和垃圾灰减少有关，所以D对。
特别是关于上面那个朋友的“总量=单量x数量”的公式请大家先不必考虑（因为想的越多可能离题目所给信息越远，而且还影响速度和正常思路，能用更直接的方法选出就直接选）
