标题: OG12- 107我脑子秀逗了吗。怎么100题以后的就是搞不懂呢。求解答,求安慰555555
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

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)

【去年S市服务站收集的垃圾都被焚化了】【焚化造成了大量的残余灰分】
【为了使今年产生的灰分量减少到去年的一半,S市重新修订了他的收集计划】
【今年,市服务站将分出足够的垃圾,使今年每卡车需焚化垃圾的量减少到去年每卡车需焚化垃圾的量的一半】

逻辑结论:每卡车负载垃圾减半会导致总燃烧垃圾灰分量减半

研究了一下我这么理解的,文章其实就在将变量和定量的问题。
1. 评估措施的题目。
2. P1:S会进行垃圾分类,将可回收的垃圾分离,以减少垃圾车量至去年的一半。
3. 答案是P2
4. 结论是说明S城采用的方法是正确的。
5. A: 只是说明了一个事实。可回收的垃圾不用焚烧。
B: 谈到成本的问题。文章没有讨论。文章专注于减少残灰的事实。
C: 可回收的占很大一部分。不代表不可回收的不增加。不可回收的是导致残灰的原因。
D: correct。要达到目的。残灰的总量=每车的垃圾产生的残灰量*有几车。文章已经说明了车的数量减少了,是需要证明另外一个变量不变。就能达到目的
E: 今年S收集到的垃圾不会比去年多。
讨论了垃圾的总量不变。与残灰的总量的这个变量无直接关系。

同问同问呀~og上对A项的解释感觉莫名其妙的,感觉和A都扯不上关系
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."  
求NN解释呀~

我错选了A

OG解释我也没明白,我自己的理解是
A只说recycling的不被焚烧,但是没说焚烧的那部分垃圾会产生多少ash。有可能,recycling的这部分没烧,但是烧的那部分产生了从前三倍的ash,那么reduce ash to half...  就不能实现相比之下,D就说得很直接啦

LZ 不够细心,从很多细节上可以看出来:
-------------------------------------------------------------------------
“residualash”,“Shelbyvillegenerates”,“revampedits”,“forrecycling”,
“ tobe”
-------------------------------------------------------------------------------

我做题的时候是做对了,问题是在后来重新分析题目的时候,觉得这道题出的有漏洞,要是答案是d的话,那么必须是今年处理的垃圾就是去年收集的那些,这样,一半一半,而且没卡车焚烧产生的ash 数量不增加,才可能是去年的一般,但是问题是,今年处理的垃圾应该是今年收集的啊,要是今年收集的总量就比去年的总量多了,那么一半一半,一半的数量也相应增加了,那么每卡车产生的ash 不变,那么ash总量还有可能增多的啊。所以我觉得还是少了一个前提~

发表于 2009-8-8 13:08:00 |只看该作者
文章结尾说通过recycle减少要焚烧垃圾的truckloads到去年的一半,以减少产生的ash到去年的一半。

产生的ash的量 = number of 要焚烧垃圾的truckloads * 每truckloads产生的ash量

number of 要焚烧垃圾的truckloads 已经减少到去年的一半了,要想产生的ash的总量为去年的一半,必须要求就是per truckloads 产生的ash量不会比去年多。否则,每truckloads要焚烧的垃圾产生的垃圾量为去年的100倍,减少一半truckloads也无济于事
