NN赐教，就是想不通啊og12 cr 26

26.When a polygraph test is judged inconclusive, this is
no reflection on the examinee. Rather, such a
judgment means that the test has failed to show
whether the examinee was truthful or untruthful.
Nevertheless, employers will sometimes refuse to
hire a job applicant because of an inconclusive
polygraph test result.

Which of the following conclusions can most properly
be drawn from the information above?

(A)Most examinees with inconclusive polygraph
test results are in fact untruthful.

(B)Polygraph tests should not be used by
employers in the consideration of job applicants.

(C)An inconclusive polygraph test result is
sometimes unfairly held against the examinee.

(D)A polygraph test indicating that an examinee is
untruthful can sometimes be mistaken.

(E)Some employers have refused to consider the
results of polygraph tests when evaluating job
applicants.
就是想不通D为什么不是，不是就是测谎试验有时候会出错吗？

恩，谢谢你啊。不过还是小糊涂中，等第二遍看的时候再纠结下，现在这道题钻进牛角尖了。

D) Untruthful is different from inconclusive. Hence, you cannot derive the main conclusion as D).

E) The whole paragraph is about CONSIDERING polygraph result, not "refuse to consider polygraph test."

这道题目我也有点糊里糊涂，我一开始就排除了A B E，不过自己的理由和解答完全不同。
我排除A是因为most太过绝对，而答案解释当测谎仪测试不确定时无法反映被测试者，这个还能理解。
排除B是因为完全不要在招聘时使用测谎仪，也有点绝对，毕竟测谎仪是偶尔inconclusive，而答案说本题只讨论inconclusive polygraph result，不是最后一句话都提到hire a job了吗？怎么能说不讨论呢？
当时排除E我是有点不确定的，看到答案说更本和讨论无关，怎么说无关呢？最后一句话不是明明说有些雇主因为inconclusive polygraph test result而拒绝hire a job？
D错误我看了上面的解释目明白了，不过还是觉得牵强，是没提到mistaken，但是不就是这个意思吗？老外那么死脑筋，推理不会吗？

谢谢！懂了

(C) is the correct. If a company uses inconclusive polygraph result to reject an applicant, it is unfair. This statement (C) properly identifies a conclusion that can reasonably be drawn from the stimulus.

As to choice (D), the whole argument is concerned only with inconclusive tests, not mistaken or false polygraph test result.  There is no mention of a mistaken polygraphy test in the stimulus.

Answer to a inference question has to be 100% true based on the stimulus.
