急,两道LSAT题

20=2=7
7. Of all the photographs taken of him at his wedding there was one that John and his friends sharply disagreed about. His friends all said that this particular picture did not much resemble him, but John said that on the contrary it was the only photograph that did.

Which one of the following, if true about the photograph most helps to explain John's disagreement with his friends?

(A) It, unlike the other photographs of John, showed him in the style of dress he and his friends usually wear rather than the formal clothes he wore at the ceremony.

(B) It was the only photograph taken of John at his wedding for which the photographer had used a flash.

(C) It was a black-and-white photograph, whereas the other photographs that showed John were mostly color photographs.

(D) It was unique in showing John's face reflected in a mirror, the photographer having taken the photograph over John's shoulder.

(E) It was one of only a few taken at the wedding that showed no one but John.

答案是D,可这是什么意思啊,不懂


7=1=19
When Alicia Green borrowed a neighbor’s car without permission, the police merely gave her a warning. However, when Peter Foster did the same thing, he was charged with automobile theft. Peter came to the attention of the police because the car he was driving was hit by a speeding taxi. Alicia was stopped because the car she was driving had defective taillights. It is true that the car Peter took got damaged and the car Alicia took did not, but since it was the taxi that caused the damage this difference was not due to any difference in the blameworthiness of their behavior. Therefore, Alicia should also have been charged with automobile theft.


19. If all of the claims offered in support of the conclusion are accurate, each of the following could be true EXCEPT:

(A) The interests of justice would have been better served if the police had released Peter Foster with a warning.

(B) Alicia Green had never before driven a car belonging to someone else without first securing the owner’s permission.

(C) Peter Foster was hit by the taxi while he was running a red light, whereas Alicia Green drove with extra care to avoid drawing the attention of the police to the car she had taken.

(D) Alicia Green barely missed hitting a pedestrian when she sped through a red light ten minutes before she was stopped by the police for driving a car that had defective taillights.

(E) Peter Foster had been cited for speeding twice in the preceding month, whereas Alicia Green had never been cited for a traffic violation.

答案是C,也没看懂什么意思

If you "没看懂什么意思", you need to read and understand first. Reasoning is seond them that.

1. It only means that the picture shows him from almost the same angel he looks at himself in the mirror.

2. "blameworthiness for their behavior" If both are of the same level of blamworthiness, they should be punished the same way. Since C says that they are of different level of that, what they got was fair. E is not related to blamworthiness.

第一题楼上的说了等于白说,文中需要解释的是为什么两人在看同一张照片的时候得出的是两个完全不同的结论,你的解释对于上述这个逻辑有什么说明作用吗?

第二题的解释还过的去

以下是引用番茄炒蛋在2003-11-14 21:38:00的发言:

Am I not clear? When you see a person, you look at him straight in the face, correct? Do you look at his image reflcted in the mirror the same way as he look at himself all the time? Do you just read a question and an answer without thinking about the implication?

还是有些疑问
照片里的新郎是镜子里的一个影像,那么这也就是新郎每天可以在镜子里看到自己的那个样子,所以他就说这张照片很象
其他人平时都是直接看到他本人的,而不是看到镜子里的那个新郎,所以说不像
但是这里又有一个问题,这面镜子又不是哈哈镜,里面看出来的人和外面看到的应该也没有什么区别啊
再请教头指点

我想这里实际上是一个中学的物理概念,镜子里面的影像和实际影像是反对称的,仔细回忆一下是这样吧。我们每个人基本上都是从镜子里面知道自己的外貌特征,虽然这种特征和实际别人所看到的(亦即客观存在的)不一致(正好是反对称);这跟哈哈镜的原理有类似的地方,只不过哈哈镜除了反对称外还有其它的变形效果。因此楼上 Mindfree 的解释是正确的。

同样的概念(虽然原理不同)也可以形成一个类似的题目:大家有没有注意到,自己听自己说话的声音和别人听到的你的声音有很大的不同。我经常听到自己的录音就很陌生,很多朋友也有这种感觉。因为人听到的自己的声音部分是从自己颅腔传导的,而别人听到的你的声音完全是通过空气传导。

看来LSAT和GMAT对 “傻子原则” 的背离度更大一些。我做这道题的时候也错了,后来很长时间才想明白。
