Critical Reasoning

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.

D. If D is negated the assumption falls apart.

It is between B and D, D is the better option though as it hits the suggestion directly.

to me D seems to be the right answer since the argument falls apart if we negate D. Please let us know the OA??

IMO is D, too.

OA: D

R u sure this question is 700 level !?

This is a badly designed question. The phrase "human contact" is ambiguous. Clearly, human contact includes touching but does "human contact" also include catching a disease from someone coughing nearby? You can make logical arguments in both directions. Thus, without changes, this question would not have made it past the experimental stage on the real GMAT.

D seems to be the best choice here
