### HideShow timer Statistics

Pharmacist: A large study of people aged 65- 81 and suffering from insomnia showed that most of insomnia' s symptoms are substantially alleviated by ingesting melatonin, a hormone produced by the pineal gland, which plays a role in the regulation of the body's biological clock. Thus, the recent claims made by manufacturers of melatonin supplements that the pineal gland produces less melatonin as it ages are evidently correct.

The pharmacist's argument is flawed in that it

(A) infers from the effect of an action that the action is intended to produce that effect
(B) relies on the opinions of individuals who are likely to be biased
( C) depends on using two different meanings for the same term to draw its conclusion
(D) confuses an effect of a phenomenon with its cause
(E) relies on a sample that is unrepresentative

D AND E are probable contenders for answer

D is wrong it does not confuse effect with cause it actually uses effect to identify cause.

But the argument sample contains aged group from 65 to 81 ,melatonin rectify problem in them by ingesting melatonin.but the same thing cannot be generalized for everyone.

What about ppl below 65 they may use some other thing to rectify as they can have appropriate level of melatonin.

Also it could be possible that melatonin refers fix at certain age and then decrease .so can't say.

Can you please explain how E is the answer? There is no 'sample' that is being relied upon here-only the claims if manufacturers. Only B looks to be the best option here. Also, are you sure this is from LSAT?

Only pharmacist is mentioned in argument so how come the opinion of individuals come because only one individual is present.
So B is wrong

Sample here is 65-81 age group.not Everytime is question stem they will mention.it is logical and you need to get through it as you read along argument.

Hope this helps

Manufacturers have made a claim that is not a 'sample'. If you understood what a sample means, then you would not be questioning my doubt. Also, yes, have to go as per the argument and not 'infer' anything here as you have mentioned. I will wait for the poster/experts to help on this. Thanks

Manufacturers claim that pineal gland produces less melatonin as the gland ages. Pharmacist says this claim is true by basing his argument on the survey taken. The sample set of survey is only those who are between 65-81 and suffering from insomnia. So we cannot conclude in general that pineal gland produces less melatonin as it ages. We may conclude that the gland produces less melatonin only in those who're suffering from insomnia. So sample set is the issue here. Hope this helped.

Cheers!

I understand what you are saying here-Thanks for explaining but the question is how is the sample 'unrepresentative'? It is certainly representative but perhaps limited. Not a great question IMO .

One of the question when it is efficient to do a little prethinking.
When I read a question I was 99% sure what the answer will be.

The argument is flawed because the passage spoke only about people aged 61-85 with insomnia. Imagine that these people had insomnia in age 30-45 for example.
They were younger. Nothing changed after that. So the argument that pineal gland produces less melatonin with age is wrong. Maybe this pineal gland produced less melatonin than in other people from the beginning.

So it is E. Unrepresentative.
