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.

B Current medical technology is not capable of detecting all carriers of tuberculosis.

Your goal is to find the weaken reason with the key concept whether tuberculosis spreads or not.

B talks about that the current medical tech will not be able to detect ALL carriers. All means 100% but nothing says they will be able to detect the 99% which is a high % and the illness could not spread.

B is also too extreme.

D is best

D doesnt make sense to me...

Just b/c TB can't be transmitted through human contact doesnt mean it cant be contracted through other means... like coughing, breathing, blood. right? If this is true, then TB can still spread, regardless of whether humans make contact.

B seems like the best answer

Please Sir refer to my explanation above why B is incorrect

Ask for further explanation if you do need it.
