Diagnostic Verbal Test No 5 Q# 12 CR

Drinking Roost, a children’s health drink, must be a good habit. This substantially increases the stamina and IQ required by children for winning competitive cricket matches. Interviews conducted with young cricketers who drank one cup of Roost each before and after the match, confirmed that the players were feeling much fresher than those who did not take the health drink

What is the principal flaw in the above reasoning?

A. Users of Brownvita, another health also claimed the same effect after consuming one cup of Brownvita before and after the event.
B. Users of Roost did not take any other drink
C. The claim was made only by small percentage of the children’s population who drank Roost in the country.
D. The claim was mainly made by children who belonged to upper strata of people, who kept good health in spite of health drinks
E. In some countries, most commercial advertisements are meant only to motivate people into action by appealing to authority rather than to inform facts
[Reveal] Spoiler: OE
A: The prime question is whether Roost can produce the said benefits; that others also can produce the same effect does not impact the argument.
B: This is a strengthener and not a flaw
C: Inadequate sampling is a major flow since it will be easy to motivate a small set of people than a larger population.
D. Strata of society is not a critical factor; notwithstanding use of health drinks, there are plenty of children with poor health in upper class due to poor lifestyles such as lack of immunity, lack of exercise, use of junk foods etc;
E: There is no advertisement that Roost is one such false claimer. So, this is not a flaw.
[Reveal] Spoiler: OA

I was stuck between C & D. Finally selected D but honestly, I felt both C & D as contenders. Here, we are concerned whether Roost was indeed a good habit and the claim of the sampled students is aligned along the same lines. We need to cast a doubt on this sample.

C says that the sample is a small percentage of children population drinking Roost. Therefore casts doubt.

But at the same time, as D says the students, from upper strata, are already healthy in spite of drinking Roost. Here I felt that the sample is not representative and hence casts doubt on the claim.

Confused. Not convinced with OE honestly. Experts inputs please :-)

Got it why D loses to C. D is not actually weakening the claim. D says mainly students from upper strata but the sample might still have students with poor health from upper strata and drinking Roost. So it doesn't really cast doubt as C does. :-)

I vote for C. it took me a couple of seconds to decide between C and D, while A,B,E are clearly wrong.

My reason is that D has a target for upper class, and the Roost works. If we know that the Roost is for everyone from the stem, then option D is correct.
C is the right choice because this option told us that the limitation of the data, which weakened the conclusion

I opted C. As the claim states that it must be good for health. And the option C casts doubt upon the sample space irrespective of the income strata i.e. in general the concerns are raised.

Chose D. Please help me eliminate C. I tel you why C is wrong. C states that 'The claim was made only by small percentage of the children’s population who drank Roost in the country.'
Now I understood from C that - 'small percentage of c's population who drank Roost' implying that out of the total population of children, only a small % drinks Roost and they were fresh. So, does not weaken.
May be you understood that - out of the c's population that drinks Roost, only a small % was fresh. Then it might weaken.

But why should not I go by my understanding and eliminate C?

It is C. Because, the claim is made by young cricketers not by cricketers from all segments including adult group.

It is not D. Because, nowhere in the argument it is saying that the claim is made by the upper strata of people.
