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.

Conclusion: All the visitors must be examined for TB.

a) Country Z, which also neighbors Country Y, has not experienced an increase in cases of tuberculosis. [Country Z is not mentioned in the argument – eliminate it]

b) Current medical technology is not capable of detecting all carriers of tuberculosis. [May be help in curbing TB, but does not help in completely address the issue – eliminate it]

c) Country X does not have the resources to examine all visitors from Country Y. [Does not help – eliminate it]
d) Tuberculosis is not spread through human contact. [Hold it]
e) Citizens of Country Y will not travel to Country X if the proposal is implemented. [Irrelevant]

Answer: D

A is the correct answer. If Country Y outbreak is the casue then other neighboring countries should also see increase incidence.

B is not correct because the questions ask if the examinations will "curb" not eliminate the spread and B assumes current medical technology will catch some buit not all carriers so it should help curb the spread.

D is not correct because human contact is irrelevant. If a carriers brings the disease to X then perhaps it is spread through the use of drinking fountations or in the air when an infected person coughs. CONTACT is not required but that does not mean that carriers cannot spread the disease in another way after entering X from Y.

What if countries Y and Z are enemies and the border is sealed ..... that could be a reason for TB not spreading to Z.... or people are not moving from Y to Z becuase Z is a very poor country with militant problems, no one wants to go there ..... There is a lot of assumption in Option A..... if there was an added line that number of people visiting Z from Y is almost same as to X... then yes, but not in its current form .....

I see that D is not airtight but the best of worse. D says the main idea that channel of transfer of tuberculosis may not be visitors, but, for instance, it may be infected water in the river that flows from country Y to country X, or imported grain, and etc.

IMO answer is D

a) Country Z, which also neighbors Country Y, has not experienced an increase in cases of tuberculosis. ( NR )
b) Current medical technology is not capable of detecting all carriers of tuberculosis. ( NR )
c) Country X does not have the resources to examine all visitors from Country Y. ( it is about curbing the spread, not eradicating it, so this point doesnt matter. )
d) Tuberculosis is not spread through human contact. ( Incase Tuberculosis is not spread through human contact, the proposal is not sensible , Best Answer )
e) Citizens of Country Y will not travel to Country X if the proposal is implemented. ( NR :- Not Relevant)

An interesting question. First, the use of 'tuberculosis' here is a red herring. CR questions do not test your knowledge of medical conditions; they test your ability to analyze an argument. Our prior knowledge of tuberculosis- that it's spread through human contact- might influence our answer here, and lead us to an incorrect analysis of the argument. Indeed, D asks us to assume something we know to be false in real life. We should not think of tuberculosis at all; we might replace 'tuberculosis' in the question with any other condition- 'insomnia', or 'stress', or 'depression', for example.

Then the structure of the argument becomes clear. There is a 'post hoc ergo propter hoc' fallacy- just because one thing happens after another does not mean one thing was caused by the other. The argument says: "Y had high levels of stress (or whatever you like) last year. X had high levels of stress this year. Therefore stress in Y caused stress in X." This is not a valid argument, at least not without further support. It may just be coincidence that X had high levels of stress the year after Y did. High levels of stress might be caused by environmental factors, economic conditions, political turmoil, etc...

The assumption is that visitors from Y brought 'stress' to X. Answer D suggests that people do not transmit stress- that the cause lies elsewhere. D is the correct answer. It's not 'airtight', of course; we can imagine scenarios where the screening would be helpful even if human contact is not the cause, but these all seem unlikely. D "most strongly suggests" that the screening won't be effective, even if it is not 100% convincing.

I'd note, finally, that B and C must be incorrect, even if we grant the assumption that tuberculosis is contagious. If tuberculosis is contagious, even screening some of the visitors from Y will reduce the spread of the disease. As has been pointed out, the question does not ask whether the medical examinations will completely eradicate tuberculosis. A is incorrect because we have no knowledge of Country Z; Country Z might have been screening all their visitors for tuberculosis for years, which might be the reason Z had no increase. Indeed, were that true, A would help to support the argument, not weaken it.

From MGMAT Explanation -

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.

According to me Option B & C both are equally good. They both are suggesting that medical examination is not going to work.

Experts please help.

Experts please help.
The question stem highlights the word "NOT." However, there is another very important word in the question stem right next to it: "Help."

(B) and (C) suggest that the plan in the question stem will be of limited use. But the question isn't asking us to weaken the idea that the plan will completely solve the problem. It asks us to disprove the idea that the plan will help at all to solve the problem. In cases (B) or (C), the proposal in the stem is no panacea, but it could still be one part in a comprehensive plan to prevent the spread of Tuberculosis. But choice (D) makes it clear that the plan won't help in the slightest--it won't do a thing! That makes (D) the only correct answer to this question.

B and D are good contenders.
In B,the use of "all" strikes the difference.B says that- Current medical technology is not capable of detecting all carriers of tuberculosis but it can detect some carriers.thus, it will help to curb the disease to some extent.

I hope its clear!

It's between B and D.

B is not strong enough. If Current medical technology is not capable of detecting all carriers of tuberculosis, then it would possibly be capable of detecting at least some carriers of tuberculosis if not all. Therefore to some extent it would be possible to curb the spreading.

D. Yes. If the spreading does not happen through human contact, then there is no point of the medical examinations.
