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?

Country Z, which also neighbors Country Y, has not experienced an increase in cases of tuberculosis.
Current medical technology is not capable of detecting all carriers of tuberculosis.
Country X does not have the resources to examine all visitors from Country Y.
Tuberculosis is not spread through human contact.
Citizens of Country Y will not travel to Country X if the proposal is implemented.

IMO B.

whats the OA answer?

IMO B

IMO B

b) Current medical technology is not capable of detecting all carriers of tuberculosis. <- correct

c) Country X does not have the resources to examine all visitors from Country Y. the question says that medical exam is to be done before entering country X.. where it is to be done is not stated.. it may be done in country Y itself... thus incorrect

Nice one..

IMO D . If it does not spread thru human contact, then examination would not curb the disease in any way.. B willl curb the disease to some extent atleast.

what is the OA. pls post the OA soon

You are correct - answer is D
I made a mistake and marked B

Here is official explanation. Note that this explanation also mentions that B also weakens the argument!


Because of the speculation that the tuberculosis outbreak in Country X was the result of an outbreak of tuberculosis in Country Y, health officials in Country X have proposed requiring all visitors from Country Y to undergo a medical examination. We are asked to find a choice that suggests that this proposal will not have the desired effect of curbing the spread of tuberculosis in Country X.

(A) This has no bearing on the situation between Country X and Country Y.

(B) This suggests only that the proposal would not prevent ALL cases. But even if the proposal does not prevent all cases, it could help prevent many.

(C) This suggests only that the proposal would not catch ALL carriers of the disease from Country Y. But even if the proposal does not prevent all cases, it could help prevent many.

(D) CORRECT. This suggests that the visitors from Country Y are not the source of the disease. Thus, testing them would likely do little to curb the spread of the disease.

(E) This does not suggest that the proposal will not help curb the spread of the disease. If the visitors from Country Y are indeed carriers, then their refusal to visit Country X will help curb the disease.

Agree with the expalnation, D should be the correct answer.

Thanks

IMO opinion it will be A

--- Because it suggests that is cases have not spread to ciity Z therefore the reason why the disease has come to city X is not because of city Y but because of another reason.
Therefore if the other reason is not found then the cases would still stay abated.

I dont think its option D becasue even though it is not through human touch, IT would also be through air or other factors that might cause infection if the person is close by though they not neccesarily might be touching each other!!

Whats the OA??

@Shivani, you are assuming lil bit extra:-)

1) people from country Z have not reported the cases of the mentoioned disease
2) country Z and country Y are similar in all respects.

given both 1 and 2, we can conclude A to be correct but withoout 2, A does not fit the bill.

Whats the OA?

shivani,

completely on board with your logic, for what its worth, i happen to have the same crooked logic that you do

I don't know if you saw the author's subsequent posts or not but he/she asserts that D is OA which i completely disagree with.

D is clearly wrong (i'd be willing to give up my GMAT for this )...TB is an airborne disease, human contact doesn't matter, stating that doesn't even help. Agree that the readers are not suppose to know that but when specified you have to account for other logically causes for a disease.


Jatinder,

i don't buy your argument. By referencing Z, we are trying to say that the vicinity to a country is not a factor and that there are local factors in play.

Hmm.. Well i still cant see the OA anywhere. But im quite sure aswell!!

Saw it where is this question from??
