Is this a flaw or a weaken question? How to identify this? Whats the main difference between the two ? and their approaches? How to use elimination to solve this? Please provide detailed explanation.

Researchers have noticed that people whose blood shows abnormally low levels of calcium usually have laryngeal polyps, which can permanently damage vocal cords and result in partial or even total loss of voice. In order to reduce the risk of polyps, the researchers recommend a diet high in calcium-rich foods such as dairy and green, leafy vegetables.

Which of the following, if true, most strongly suggests that following the researchers' recommendation would NOT be effective?

a)Dairy contains compounds that are difficult for many people to digest.

b)Laryngeal polyps sometimes disappear without treatment.

c)Laryngeal polyps cause a change in body chemistry that blocks the absorption of calcium.

d)Fresh vegetables are not always available in all seasons.

e)Low levels of calcium can sometimes be remedied with vitamin pills.

sidhans, kindly post the OA
I got C.

(C) Laryngeal polyps cause a change in body chemistry that blocks the absorption of calcium.

Ok now the researchers recommend High calcium diet....and Option c says its difficult/Blocks the absorption of calcium....

Correct me if i am wrong....

I am wondering how the OA -
[Reveal] Spoiler:
C
could be correct???
In the Stimulus, the researchers are discussing ways to reduce the risk (i.e preventing the disease than curing the disease), but the OA provides after effects of the disease than preventing. Isn't something wrong with the OA.

Hi navigator123,

The stimulus says that low calcium causes laryngeal polyps (low calcium -> laryngeal polyps)
but if we can prove that relation b/w cause and effect are in opposite way i.e. if we prove that (laryngeal polyps -> low calcium) then the researcher's reccomendation will not be effective.
