We are looking to weaken the argumentLet me break down the argument...
Asthmagon was long considered the most effective of the drugs known as beta-2 agonists, designed to alleviate asthma attacks.(background) However, (
contrast) studies conducted in Rhiago between 1981 and 1987 revealed that nearly one out of every five of the asthma patients under observation who took asthmagon suffered serious side effects after taking the drug. Citing this statistic,
some doctors argue that asthmagon should be banned as an anti-asthma drug.
This is the conclusionWe want to weaken the conclusion that Asthamagon should be banned. So, look for something that goes against the glaring evidence provided by the statistic.
Which one of the following, if true, most weakens the case for the proposed ban of asthmagon?
(A) In Rhiago, where asthmagon had been the most widely prescribed of the beta-2 agonists, the number of asthma deaths increased between 1981 and 1987.
Bad. This strengthens the argument.(B) Many of the patients under observation to whom asthmagon was administered had not previously taken a beta-2 agonist.
Hold. Not good enough to weaken as the drug could be first in line and hence this could be a valid reason to ban it.(C) Despite the growing concern about the drug many physicians in Rhiago still prescribe asthmagon to asthma sufferers.
Irrelevant to the argument(D) Among the patients observed, only those who had very high cholesterol counts suffered side effects after taking asthmagon.
Bingo! Something other than the drug is causing side effects - it is the high cholesterol - so we can get away by just allowing the drug to be used by people with normal cholesterol and not ban the substance completely(E) Asthmagon increases the severity of asthma attacks in some people because the drug can cause damage to heart tissues.
Bad - this strengthens the argumentHence
Option(D) is our choice.Best,
