hey experts ! took 1 mins 07 secs
it was quiet tough between C and D
Unfortunately end up marking D
can someone please explain why D is false.
Hello,
Anshuman0902. I would be happy to help clarify the matter. If you look at the passage and answer choice again, perhaps a little closer to
exactly what (D) says, you should be able to spot the problem.

Page: 521
When a polygraph test is judged inconclusive, there is no reflection on the examinee. Rather, such a judgement 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?
(D) A polygraph test indicating that an examinee is
untruthful can sometimes be mistaken.
Where does the passage talk about the results of a polygraph showing the examinee to be
untruthful? Nowhere. That word only appears in the sentence that refers to a test that
has failed to show whether the examinee was truthful or untruthful. Such a test would be deemed
inconclusive, according to the first line of the passage. Thus, we cannot comment on what (D) is saying. There is simply no evidence to lean on in the passage for support.

Does the passage talk about this type of test result? It sure does, and the last sentence corroborates that such a test is, in fact,
sometimes unfairly held against the examinee. There is nothing to argue against here, so it must be our answer.
I hope that helps. Be careful not to be led astray in CR. Make sure the words match up.
Good luck with your studies.
