CR - Infer Conclusion

by karthikpandian19 » Sat Jun 30, 2012 3:14 am
Tests for the presence of a certain drug are sometimes judged "inconclusive," which is no reflection on the examinee. Instead, such a judgment indicates only that the test cannot determine whether or not the drug is present in the body of the examinee. Nevertheless, many insurance companies will throw out any claim of workplace injury if the claimant's drug tests do not yield conclusively negative results.

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


(A) Most examinees with inconclusive drug test results are in fact drug users.

(B) Drug tests should not be used by insurance companies to evaluate workplace injury claims.

(C) A drug test indicating the presence of a certain drug can sometimes be mistaken.

(D) An inconclusive drug test is sometimes unfairly held against the examinee.

(E) Some insurance companies have refused to consider the results of drug tests when evaluating workplace injury claims.

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


(A) Most examinees with inconclusive drug test results are in fact drug users. --- Out of context

(B) Drug tests should not be used by insurance companies to evaluate workplace injury claims. ---I don't think the issue here is to not use the test totally but to not use the test unfairly against the examinee. So B is going a bit too far, hence incorrect.

(C) A drug test indicating the presence of a certain drug can sometimes be mistaken. --- Out of context

(D) An inconclusive drug test is sometimes unfairly held against the examinee. --- True, this is suggested by the passage.

(E) Some insurance companies have refused to consider the results of drug tests when evaluating workplace injury claims.--- Irrelevant.

OA is D

We must identify an appropriate inference from the argument given. The prompt first tells us that a drug test may yield an "inconclusive" result, which means only that the test cannot determine whether the drug is present in the body of the examinee. Second, the prompt tells us that nevertheless , insurance companies will not honor workplace injury claims if the claimant's drug tests are inconclusive result or positive.

Choice D: The author states both that inconclusive results are no reflection on the examinee and that examinees whose tests come back inconclusive are nevertheless denied their claims. This does indeed suggest that inconclusive tests are "sometimes unfairly held against" examinees. Choice D is correct.

Choice A: False. The author explicitly says that an inconclusive result cannot determine whether or not the drug is present in the body of the examinee. To claim that "most examinees" with inconclusive results are using drugs is not supported by the argument.

Choice B: Extreme. The fact that tests sometimes produce inconclusive results does not entail that insurance companies "should not use them," only that the tests are imperfect. Besides, this argument is not about what companies should do.

Choice C: Unsupported. The author gives no indication about the accuracy of conclusive test results. Only inconclusive tests are discussed.

Choice E: Unsupported. While some insurance companies might have a good reason to not "consider the results of drug tests," the author never indicates that any insurance companies currently disregard these tests.
