A physician who is too thorough in conducting a medical checkup is likely to subject the patient to the discomfort and expense of unnecessary tests. One who is not thorough enough is likely to miss some serious problem and therefore give the patient a false sense of security. It is difficult for physicians to judge exactly how thorough they should be. Therefore, it is generally unwise for patients to have medical checkups when they do not feel ill.
Which one of the following, if true, would provide the most support for the conclusion in the passage?
(A)
Not all medical tests entail significant discomfort. - WRONG. It's not about all the tests.
(B) Sometimes unnecessary medical tests cause healthy people to become ill. - CORRECT. Not the best of the answer one is looking for but best among the choices available here.
(C)
Some patients refuse to accept a physician’s assurance that the patient is healthy. - WRONG. Exceptions are always there.
(D) The more complete the series of tests performed in a medical checkup, the
more likely it is that a rare disease, if present, will be discovered. - WRONG. This most likely does the opposite to the conclusion.
(E)
Physicians can eliminate the need to order certain tests by carefully questioning patients and rejecting some possibilities on that basis. - WRONG. What a physician should do it does not matter. It's not doing anything to the conclusion as it does not point out how patients are unwise to go for checkups.
This question requires a choice that either strengthens the conclusion or does nothing to the passage(but that depends on other choices that most likely weaken the conclusion). Also, this can be an assumption. So, a choice can either a sufficient(strengthener) or an assumption(necessary).
Answer B.
