夜深人静，发一道智商题，限制1.5分钟答完 (老将小将）

[emanuel]

The R, a passenger ship, sank as a result of a hole in its hull, possibly by caused by sabotage. Normally, when a holed ship sinks as rapidly as the R did, water does not enter the ship quickly enough for the ship to be fully flooded when it reaches the ocean floor. Full flooding can be achieved, however, by sabotage. Any ship that sinks deep into the ocean when not fully flooded will implode. Deep-sea photographs, taken of the sunken R where it rests on the ocean floor, reveal that the R did not implode.
Which one of the following must be true on the basis of the information above?
A. The R was so constructed as to reduce the risk of sinking by impact.
B. If the R became fully flooded, it did so only after it reached the ocean floor.
C. If the R was not sunk by sabotage, water flooded into it unusually fast.
D. If the R had sunk more slowly, it would have imploded.
E. The R was so strong constructed as to resist imploding under deep-sea pressures.

说明选项理由，时间1.5分钟。（难易程度 1-10, 是3)

E

[subsub1]

c呗
船没implode，一定进满水了

[none]

。。。。。。

[YJM1024]

C

R 肯定 fully flooded 。 fully flooded 的原因可以是 sabotage 。 R 可能是 sabotage ， 但是如果不是的话，水流进来就是很快的了。

[none]

呃。。。
但也可以是这个船就是这样设计的，使得下沉时在低于某个深度后自动fully flooded，以保持沉船的整体性。
sabotage也能造成fully flooded，不用unusually fast flooding。
所以C改成the R might not be sunk by sabotage and water flooded into it unusually fast.更容易接受。
anyway，根据出题一般的调性，答案确实应该是C

C

R 肯定 fully flooded 。 fully flooded 的原因可以是 sabotage 。 R 可能是 sabotage ， 但是如果不是的话，水流进来就是很快的了。

D

其它选项有的反了。
B the R became fully flooded, it did so only after it reached the ocean floor.
原文：Normally, when a holed ship sinks as rapidly as the R did, water does not enter the ship quickly enough for the ship to be fully flooded when it reaches the ocean floor. Full flooding can be achieved, however, by sabotage.
即使sabotage，也是隐含在reaches the ocean floor之前，而不是之后
C. If the R was not sunk by sabotage, water flooded into it unusually fast.
与上面的正好相反，sabotage快，其它原因慢
E 也是反的。

A. The R was so constructed as to reduce the risk of sinking by impact.
没说，只是强调从一般沉船出发，船沉到海底会瘪，而本船未瘪。

D if the R had sunk more slowly, it would have imploded.

前面讲water does not enter the ship quickly enough for the ship to be fully flooded ，而Full flooding can be achieved, however, by sabotage. 后面由海底照片反推已经Full flooding，那么很显然水进入本船是相比于第一个条件快的，而第一个条件下有空气，在海底会被压瘪。所以符合。

这是LSAT的题？还是GRE的？

看不懂。能翻译成汉语吗？

[newZero]

正确答案是啥？为啥觉得全都不对

[StMichael]

C

就是充分和必要条件什么的简单逻辑倒来倒去

还限时间，因该是LSAT，楼主在准备考么？

（刚发现不能短时间连续发贴）

[verdelite]

一打开就不想做，因为一分半估计读不完题目，LOL

还是老买提人才济济啊。这是高二参加集训的难题本一道题，现在咋一看没有反应过来。老将们都对，答案是C。
笔记本上记着，“注意阅读第二句，已经承接第一句论点，说明如果是人为毁坏，那沉船的时候水就不会快速flood， 魔鬼在细节里“
所以，几个老将都说得很对，分析得很对，从物理到文法再到逻辑倒推上，小弟佩服佩服，比大妈网智商不是高一点点。

连续重复发帖，活人变成机器人？

[StMichael]

这应该是从LSAT上扒下来的题，就那个路子。

熟悉套路了就不难了，就是用很复杂的语言覆盖很简单的逻辑。

这题就是充分条件，必要条件的形式逻辑题。把复杂的语言符号化就容易多了。 a-->b-->c; c not --> b not-->a not

不要小看大妈网，有好些律师，有些是正经JD, LSAT拿过高分的。

[Sususu]

当年我老考gre 逻辑就是拿lsat 练手。最后果然满分。

这题是c，就是考你是否迅速剔除无关条件，然后基本的逆否逻辑

[marclee]

显然是C吗！

做过GMAT逻辑题的这个算个屁。没做过的楼上的几个还分析得头头是道没找到C的，就别做了。

[srx]

C

[minquan]

Normally, when a holed ship sinks as rapidly as the R did, water does not enter the ship quickly enough

这句是water does not enter the ship quickly enough
凭什么支持C的not sabotage -> usually flood fast?

这明明是flood slow
