The number of new cases of tuberculosis diagnosed in Country X increased dramatically this year. The country's news media have speculated that the sharp increase in new cases is the result of the tuberculosis outbreak that occurred in neighboring Country Y last year. Health officials in Country X have therefore proposed that all visitors from Country Y must submit to a medical examination before entering Country X. Which of the following, if true, most strongly suggests that the proposed medical examinations will NOT help curb the spread of tuberculosis in Country X?
A. Country Z, which also neighbors Country Y, has not experienced an increase in cases of tuberculosis. B. Current medical technology is not capable of detecting all carriers of tuberculosis. C. Country X does not have the resources to examine all visitors from Country Y. D. Tuberculosis is not spread through human contact. E. Citizens of Country Y will not travel to Country X if the proposal is implemented.
NN, the answer to this question is D. I chose A instead. The explanation says that A has nothing to do with the question above. But I think that A rules out the possibility that it is the people in Y that transfer the disease. What's wrong with my reasoning? Can anyone help me? I'd be appreciated.
