OG-11-112 and OG-11-114 困扰了我一晚上~~~

112. In test for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test has the lowest proportion of false positive results.

which of the following, if true, gives the most support to the recommendation above?

A. The accepted treatment for pironoma does not have damaging side effects

B. The laboratory test htat has the lowest proportion of false positive results causes the same minor side effects as do the other laboratory tests used to detect pironoma.

C. In treating pironoma patients, it is essential to begin treatment as early as possible, since even a week of delay can result in loss of life.

D. The proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma.

E. All laboratory tests to detect pironoma have the same proportion of false negative results.

这道题我没读太懂, 为什么选E呢? D又是什么意思呢?

114. According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two highway brieges along the route the rail line serves. Although the proposed improvements are indeed needed, the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.

Which of the following, if true, would cast the most doubt on the effectiveness of the authority's plan to finance the proposed improvements by increasing bridge tolls?

C. Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.

D. When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.

我是不太明白C在说什么, D选项是答案, 但里面说的20% of the regular commuter traffic也不是很多啊,觉得没什么影响.

 

谢谢大家帮我解答了!!!

112．题目表达的意思是

a.测试中有两种错误，一种是false positive results，另一种是false negative results

b.physicians为了更准确的发现pironoma应该用false positive results最低的实验室的数据

在a条件下要支持b这个结论，应该想到的是false positive results最低的实验室的false positive results要小于等于其他实验室的数据，只要这样才能保证false positive results最低的实验室的准确率最高,只有选择e

 

其实题目本身没什么难度，就是提干中的迷惑成分有点多，呵呵

至于d，多做些题目，多体会，就很好判断这种无关选项了

打错字了，不好意思

114．和上题一样也是题干中无用的迷惑成分比较多，把他们剥离，其实表达的意思就是：TTA认为提高汽车过两座高速公路桥的toll可以finance the improvements.

问题是削弱这个结论，首先想到不能多收到足以finance the improvements的tolls, 然后是有其他途径可以finance the improvement（最强的削弱是反例）

看选择支，只有d符合

 

其实两个题目本身的逻辑都不是很复杂，只是题干部分的无用成分比较多，个人建议楼主应该在阅读上下点功夫，毕竟阅读才是根本！呵呵

谢谢楼上大牛的详细讲解!!!

不过我还在内20%上犯嘀咕

毕竟只有20% driver选其它路走

内个虾米, 我再加问一题行吗?

123. Codex Berinensis,a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copyist, but the remaining 20 pages are by three different copyists, which indicates some significant disruption. Since a letter in handwriting identified as that of the fourth copyist mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year.

D. There was only one outbreak of plague in Florence in the 1100's.

这题我完全没思路,后面的解释看了但还是不清楚

逻辑真是让我不知道该怎么办了

eremitechow 谢谢哈 一说我就明白了
