Question

Hi all GMAT teaching Institutes,

I have come across a few Qs mentioning you as source but there is a flaw in logical reasoning concerned in these Qs. I did raise the queries in the THREAD where these were being discussed but I am sorry to tell you that the you all have avoided the queries keeping the principle of  silence is the best policy , while answering other queries that could be tackled.
The AIM is, in no way, to project your faults, after all it may be correct as it is. Or, it is always possible to error once in a while when we are talking of such a large pool of Qs you all create. But once known, will it not be better and obligatory on you to clarify or review your Qs, so that students using this platform do not carry wrong learnings.
I will reproduce few Qs in this thread and would request you to clarify.

Regards..

Hi,

lets see what the paragraph tells us..
 the average income of those below poverty line has increased by 6% and others by 13.4%. Yet the standard of living has not improved. 
 
what we have to do?
 STRENGTHEN it..

What should come in the mind straightway....
 If increase in income has not led to improvement in standard of living, then the only reason is this 6% has not offset the increase in prices in these 5 years..
 
lets see the OA..

B. During the last five years, the cost of medicine for people living below the poverty line has increased 6%. 
CORRECT but only because no other choice is better. 
 here it tells us that the prices of medicine have gone up by 6%, thus eating into the increase in income...
Only PROBLEM is we are just talking of one aspect of measuring standard of living,. it may be possible that everything else has become cheaper..
we go by what is avail

VeritasPrepKarishma  and @VeritasPrep, the choice C has to be picked up only because of compulsion. 
In reality, it cannot be said to strengthening it.

Hi mikemcgarry , I would put this Q to you, since the Q is shown to be from Magoosh... I'll just speak of the OA, which is D.. Crux of para since three privately owned hospitals have come up, the county executives intend to close down one of the seven county run hospitals to save money , an action that should have least/fewest negative health consequences for citizens of the county,.. Recommendations recommendation is to close down the one with the highest fatality rate... what does the Q asks us? Which of the following, if true, most seriously calls into question the consulting firm's recommendation for the choosing the hospital to close?.. what are we required to find something Questioning closing down the one with the highest fatality rate .. what does the OA, D, convey.. D) The most at-risk patients throughout the county are referred to those public hospitals that have a high concentration of trained specialists on staff... it conveys that most at-risk patients come to place with most trained specialists.. What does the OA lack? .. Connecting two different terms through ASSUMPTION 1) The choice does not connect most at-risks with most fatality rate. 2) It may just be that the hospital with the most fatality rate is at a hospital where lesser at-risk patients come, but the inefficient staff, scanty resources, and other reasons related to the hospital have led to the highest mortality rate at that hospital. 3) Also, It may just be that the hospital recieving the most at-risks cases has the least fatality rate because of the efficient staff, resources, and other reasons related to the hospital have led to the highest mortality rate at that hospital. 4) Why are we assuming that most at-risks will lead to most fatality rate. To answer this Q, we have to limit ourselves to what has been provided to us. mike, I would appreciate that answer be provided without any prejudice to the source. I have seen many sources simply donot reply when it comes to one of their Q, if they go wrong on an issue and thereby imparting or creating a doubt in students mind. I think accepting that, yes, some mistake has happened can only increase the acceptability of the source. I, too, would accept if I have gone wrong in my assessment of the Q, since its early morning and I have just had a glance on this Q and these were first thoughts. For those interested, the intelligent chetan2u and I discussed this question at length here: lawrence-county-has-seven-county-run-hospitals-211711.html Please go there to see the discussion and join it if you like. :-)

A Query asked on 25 dec 2015 is reproduced.. 
Hi,
An example of a Q where you are forced to choose an answer with flawed logic because other choices are even worse.

A. It is possible to hear without the use of the three tiny bones in the inner ear.
  Only possiblity of a correct answer. because ultra thin fibreglass is used in its place to enable a person to hear..
 but logic is questionable.  
 since artificial limbs are utilized by few runners, can we say that it is possible to walk without legs.. 
In this Q We can say that "It is possible to hear by replacing the three tiny bones in the inner ear with a single piece of ultra-thin fiberglass" 
but certainly not  It is possible to hear without the use of the three tiny bones in the inner ear. ...
It says more to the effect that " these bones are there, dont use them but still enjoy hearing"

B. Most hearing loss is due to neurological malfunctioning.
 not necessary. We can only conclude that not most of hearing problems are due to the three bone issue but nothing about neurological malfunctioning.

C. More people have impaired hearing because of neurological damage than because of damage to the tiny bones of the inner ear.
 same as B. not necessary. We can only conclude that not most of hearing problems are due to the three bone issue but nothing about neurological malfunctioning.

D. Hearing loss due to neurological damage is more severe than hearing loss due to damage to the tiny bones in the inner ear.
 severity has not been talked of. Out of context

E. The use of fiberglass cannot help people who have lost hearing due to neurological damage.
 A tempting choice. But we are talking of effects of a specific medical procedure, its a different matter that it uses fibreglass.. may be some other procedure using the fibre glass may be effective

ans A..
But would request some Veritas rep to comment on logic of A..  VeritasPrepKarishma

Hi,
the logic of the main statement itself is flawed..
 The Q would have been better had it asked for "flaw in the logical reasoning". ...

The logic in this Q is ..
all the As will have done B..
so since C is doing B, he will be A..
 all the As will have done B..  does not mean all doing B will be As..

But taking the Q as it is, answer will be C..
For becoming a medallist .. it is necessary that many hours  (requirement 1)  of trg under elite coach  (requirement 2) ..
we know he has coached under elite coach..
so if he has to win a medal, he has to have trained for many hours..

@veritasprep ,  VeritasPrepKarishma  ,  VeritasPrepBrian  ,  VeritasPrepBrandon ..
It would be better if you change  therefore it follows logically that Michael will win a medal in competition.  to  micheal wins a medal in competition , to make the Questin logical
