74. (28254-!-item-!-188;#058&002906)

Comcorp Shipping Clerk: Last week, no shipments of building supplies were sent out on Friday. The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies. Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.

If the shipping clerk’s statements are true, which of the following must also be true?

A. All of Comcorp’s shipments of building supplies last week were specially ordered.

B. None of Comcorp’s shipments sent on Friday of last week was sent to Truax Construction.

C. None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.

D. None of Comcorp’s shipments sent on Thursday of last week was sent to Truax Construction.

E. All of Comcorp’s shipments of building supplies last week were sent out on Thursday.

我选的D，答案是C

The
five specially ordered shipments sent out last week were sent out on
Thursday, and each of those specially ordered shipments consisted
entirely of building supplies.
关键是对这句话的理解：注意特指，那5个特殊箱子是在周四送出的。

并没有说周四只送了 5个 special order，如果周四还送了普通的 order，那么有可能还是有送去comcorp的order。

D. None of Comcorp’s shipments sent on Thursday of last week was sent to Truax Construction.
E. All of Comcorp’s shipments of building supplies last week were sent out on Thursday.

这个题目我也错选D，注意这个题目和GWD不同，我把GWD的题目贴在这里，供大家做个比较和斟酌吧。

GWD-3-Q20:
Shipping Clerk: The five specially ordered shipments sent out last week were sent out on Thursday. Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.

If the shipping clerk’s statements are true, which of the following must also be true?

A. At least one of the shipments sent to Truax Construction last week was specially ordered.
B. At least one of last week’s specially ordered shipments did not consist of building supplies.
C. At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
D. At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
E. At least one of the shipments sent to Truax Construction last week was sent out before Friday.

這題的關鍵在於是問must also be true
所以題目說
The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies.
Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.
可以確定的是 4 shipments were sent to TC last week≠5 specially ordered shipments =>(C)
但是(D)C上星期二送出去的貨物沒有一個是送到TC的-->則無法明確推知

作者: cynthia627 时间: 2009-12-18 18:36
The five specially ordered shipments sent out last week were sent out on Thursday,
主要是这句话的理解。这句话只是说五个特别预定含有BS的实在周四发出。并没有说周四发出的只有五个含有BS特别预定的货物。所以D那个选项无从推断

明白啦！恍然大悟！

作者: bendrift 时间: 2010-7-4 10:31
做XDF小蓝看到这道题,做对了选E,但是一直对C,D,耿耿于怀.想了十分钟,拿出来和大家分享一下.

GWD-3-Q20:
Shipping Clerk: The five specially ordered shipments sent out last week were sent out on Thursday. Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.

If the shipping clerk’s statements are true, which of the following must also be true?

A. At least one of the shipments sent to Truax Construction last week was specially ordered.
B. At least one of last week’s specially ordered shipments did not consist of building supplies.
C. At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
(至少有一个货物不是在Thur发出的->那么有可能是4个货物都不是Thur发出的而在Friday发出,可见C表述中可能存在的情况是错误的,所以C是错误的.也就是C蕴涵的各种情况中存在错误的.)
D. At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.(用类似的方法,至少有一个货物是Fri发出的->也就是可能四个货物都是Fri发出的,这也是错误的,不可能四个货物都是Fri发出.D蕴涵的各种情况中存在错误的.)
E. At least one of the shipments sent to Truax Construction last week was sent out before Friday.

总结一下整体思路：

1. 没有装 building supplies 的船周五发出（a）；specially ordered 的船周四发出，且都装 bs （b）；发往 TC的船都没装 bs （c）。

2. 选项A：所有装 bs 的船都是 specially ordered 的。
选项B：没有船周五发往 TC。
选项C：没有发往 TC 的船是 specially ordered 的。
选项D：周五没有船发往 TC。
选项E：所有装 bs 的船都是周五发出。

3. 选项A 对应题干 b，但 b 不能 -> A。
选项B 对应题干a + c。（a + c）= 有可能有没装bs的船周五发往TC 不能 -> B。
选项C 对应题干b + c。（b + c）= 没有周四发出的 specially ordered 的船发往 TC （取非，若有，则必定装有 bs，与题干 c 矛盾）-> C选项。
选项D 对应题干a + c。（a + c）不能 -> D。
选项E 对应题干a。E 与 a 矛盾，所以不正确。

考试时碰到这种题目就………………纠结了

作者: chxingsh 时间: 2011-6-20 15:33
是啊考试遇到这题咋办啊！！

作者: rainbowmanutd 时间: 2011-6-21 12:04
D. None of Comcorp’s shipments sent on Thursday of last week was sent to Truax Construction.
不能推出，虽然文中说5个specially ordered在周4送出去了，但并没有说周4只送了这5个，也有可能送了另外没有bs的给T在周4

作者: superbat28 时间: 2011-9-11 17:45
我还是觉得C也牵强啊。。

文章也没说一周里所有specially ordered都是有building supply的啊。。它只是说周四那5个specially ordered是有BS的。。那C的结论None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.

我觉得欠考虑。。万一这个TC收到了“周一的specially ordered却又没有BS的船”咋办……

然后我就纠结许久，觉得一个都不对。。。

作者: ccfish9 时间: 2011-9-27 15:07
我觉得这题不难~但是下的那个版本悲催地写错答案了还分析了一堆我越看越不能苟同就上来找答案。

题目：没有BS是周五送出的，有四个SS周四送出，SS属于BS。有四个shipments送到TC这个地方，告诉我们送去的四个shipments不属于BS（但没说究竟是什么）。must be true

选项：A.该公司上周的所有BS都是SS（SS属于BS，逆推不成立）
B.周五送出的shipments都不是送到TC的（题目只说周五不送BS，而送到TC的都不属于BS因此无法推出）
C.送到TC的全都不是SS（SS属于BS，送到TC的都不属于BS，正确。大家画个韦恩图就知道了——就是那个AUBUC圆圈的图，BS是大圈，SS是小圈包含在内，到TC的在圈外）
D.周四送出的所有shipments都不是送去TC（题目只说周四送了四个SS并没说only four SS，因此推不出来。做逻辑切忌在题目表面逻辑后进一步自己进行推理。）
E.所有上周发的BS都在周四发（同D.题目只说周四发了四个SS没说总共发了四个SS，就算总共发了四个SS，BS还包含其他的东西，推不出）

希望我的思路能帮到大家(*^__^*) ……

读完题后，首先有几个概念special order---not sepcial order, building order--not building order, 可能组合S-B, S-NB, NS-B, NS-NB.
重点词组：consist of 由...组成
题干：1 FRIDAY: 没有S-B, NS-B, 可能有S-NB,NS-NB
2 THURSDAY: 有SB, 可能还有NS-B，NS-NB，本周所有的S类order, 即5个都在周四发出
3 C-------T, 没有S-B,NS-B,可能有S-NB,NS-NB
推理：但由2知，FIRDAY不可能有S类的shipment，修改条件1 FRIDAY: 没有S-B, NS-B, S-NB,可能有NS-NB
所有的S为SB, 不可能有S-NB 修改条件3 C-----T: 没有S-B,NS-B,S-NB,可能有NS-NB

A. All of Comcorp’s shipments of building supplies last week were specially ordered.
周五可能有NS-NB,周四也可能有NS-NB，错
B. None of Comcorp’s shipments sent on Friday of last week was sent to Truax Construction.
周五有NS-NB, C--------T若是NS-NB, 则可能在周五发出，错
C. None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.
所有的special order 都在周四发出，且都为buildingorder，而C----T,没有Building order, 故C----T的都不会是special order, 由条件3推理也可看出
D. None of Comcorp’s shipments sent on Thursday of last week was sent to Truax Construction.
周四若为NS-NB,则有可能，错
E. All of Comcorp’s shipments of building supplies last week were sent out on Thursday.
还有周一二三bla.....,错

笨办法，但还算清晰

这类极品题，很像楼上说的韦恩图，考试时，容易混乱，把文中没说明的部分补出来，就一目了然了，要细心。

" The five specially ordered shipments sent out last week"的定冠词the是否明确表达了“上周只有5个特定的运单”这个意思？
只有the表达了这个意思，C才是正确的。

作者: 汪寒寒 时间: 2012-1-17 02:25
这一题众说纷纭，其中蒙对后然后上来扯淡的不少。
我只想提出一点，难道题目很明确的说了specially ordered shipments就只有装载building supplies才会发生？

作者: 司马忆云 时间: 2012-4-18 19:02
但是题干中也没有说last week，只有这五个special order啊？

作者: 911cai 时间: 2012-5-16 14:56
题干说明了，上周只有5个Special Order.

原题干-------- ''The five special order （sent out last week ）are sent out on Thursday.'' 其中，（）中sent out last week 修饰the five special order, 定语完全修饰并限制了这五个special order是上周发出去的全部的SPECIAL ORDER，即说明了上周发出的special order 都是周四发的。

如果——--Last week , the five special order are sent out on Thursday.这句话就不能推出上周只有5个Special Order 了。

貌似限定性修饰是将范围缩小，表示的是特指上周发出的那五个special order吧，并不能说明上周发的special order只有这五个。如果表示泛指，表示上周发的就只有这五个，应该是用非限定性修饰吧。。

看过这条后发现其实这题要理解清楚三句话的含义：
第一句noshipments of building supplies were sent out on Friday.说明周五没有BS船
第二句Thefive specially ordered shipments sent out last week were sent out on Thursday,and each of those specially ordered shipments consisted entirely of building supplies.上周只发生了5个SS，并且都在周四寄出，还都是BS
第三句Four shipments weresent to Truax Construction last week, none of which consisted of buildingsupplies.上周有4条船去了T，并且没有BS

只要抓住了三句话里面的限定条件，那么就好判断选项了，逻辑题每次我老错就是没能把句子意思给完全弄明白，似懂非懂的，要不就是没注意到限定条件，要不就是因果关系理解反了……其实题目真正理解了，逻辑关系也就很清楚了

我也想说只能这个原因了，加了the，就是说上周只有这个5个special ordered。如果有多于5个，那么就不能加the了。。。细细体会下~~~

我里个去啊。。。。我搞了将近40分钟这题。。。。。。。。。。

终于比较清晰的理清思路。
如下。。。。。仅供参考

上周五，没有发出装BS的船。但有可能发出没BS的船。

上周四，发出了5个特定且是BS的船（这周只发了5个特定）。但有可能发出没BS的船和有BS没特定的船。

上周，TC收到了4个没BS的船。

A错。谁知道上周四有没有发出BS没特定的船。

B错。上周五有可能发出没BS的船。

C对。因为有特定的穿必定是BS船。

D错。上周四可能发出没BS的穿。

E错。周一二三也有可能发BS船。

我的方法大家试试看，每个选项开头At least one of改成None of …，也就是取非，那么你将会发现只有E取非后不成立，由此推出E项

虽然可能不是最有效的，但是我觉得是比正向思维解题快速很多！

作者: yuoasd 时间: 2018-6-12 20:48
上周四发出5个特殊订单
所有building supplies在周五发出
周末停止发货
4个订单发到TC
只有3个包括building supplies

由此，可以推测，至少有一个不是周五发出的，既然周末不发货，那么剩下的这个是在周五前发出的！！！
而且上周四发出的5个特殊订单并没有排除包含building supplies的可能！！！

If the argument is true, something must be true

你以為在考must be true, 其實他在考的是necessary assumption ( 必要假設）

Core of the argument:

1. If shipments of building supplies ---> Not on Friday

2. If 5 specially ordered shipment be sent out ---> consisted entirely of building supplies ---> It must be on Thursday

3. 4 shipments ---> TC ---> no building supplies

lets see the answers

A. Not necessary true

B. We only know that no building supplies were sent on friday and that all 4 shipment without building supplies are sent to TC. ( Shell game answer, could be true, could not be true )

C. Totally correct answer. Think in this way that if all 5 specially ordered shipment must be entirely building supplies, and none of the building supplies were sent to TC, then apparently it must be true that it is impossible to have any specially ordered shipments sent to TC.

D. 1. 我們知道五件特別配送在禮拜四送, 但是不代表禮拜四只送五件特別配送

阿美夜總會有五個小姐會在禮拜四出現, 但是不代表禮拜四的阿美夜總會只有五個小姐。

E. You can't infer that.
