ALL choices except D are too extreme in the language and D flows directly from the PARA..

A. Individuals who avoid eating mercury-rich fish face  no risk of increasing toxins  in the bloodstream.
 NO risk!!!.. there can be many other reasons that can lead to excessive mercury

B.  Individuals who do not eat mercury-rich fish regularly  will have a lower risk of developing increased toxicity in their bloodstreams as they age.
 Again ALL individuals!!! - some may have some other reasons to develop excessive mercury

C. Abstaining from mercury-rich fish altogether is  the most effective method  of lowering toxicity.
 MOST effective!!! - not mentioned anywhere

D. An abundance of mercury-rich fish will increase toxins in the bloodstreams of  some people. 
 Correct

E.  Only abstaining from mercury-rich fish  is necessary to lower toxicity levels in the bloodstreams of individuals of average weight.
 ONLY!!! - extreme again

D

I guess the right option is incorrect because it states "An abundance of mercury-rich fish will increase toxins in the bloodstreams of some people." that abundance of fish can happen anywhere such as either in pond or in river. It doesn't say about the consumption of that particular fish.

Please correct me if m wrong ?

I agree also there is a strong transition in language. The argument says that eating mercury fish "may" increase toxicity. This choice says that eating mercury rich fish "will" increase toxins. If all other options are too extreme, this choice stands no different.

For suppose, There is a seller of Mercury rich fish but he won't eat it, does it increase his toxin levels ?. It is still considered as an abundance of mercury rich fish. So according to this option not only those who EAT abundance of mercury rich fish BUT ALSO stay near or abundance of mercury rich fish in water, elsewhere, will also increase the toxin levels in some. I think the wording is incorrect. that's why I did not chose D.

abhimahna, GMATNinja, can you please help me with my query.

Hey  Nightmare007  ,

I completely agree to your point.

Being something in abundance doesn't mean we are going to consume it. I also didn't pick D at the first go but later realized that all the other answer choices are too extreme to select.

I would call this question a POOR quality question and move on.

Does that make sense?

Which of the following is a correct inference that can be drawn from the information provided?

A. Individuals  who avoid eating  mercury-rich fish  face no risk  of increasing toxins in the bloodstream.

B. Individuals  who do not eat  mercury-rich fish regularly will have a lower risk of developing increased toxicity in their bloodstreams  as they age.
 
C.  Abstaining from mercury-rich  fish altogether is the  most effective  method of lowering toxicity.
  
D. An abundance of mercury-rich fish will increase toxins in the bloodstreams of some people.

E.  Only abstaining  from mercury-rich fish is necessary to lower toxicity levels in the bloodstreams of  individuals of average weight.

1 .First of, the tone of the passage is soft/general, so any answer choice using extreme tone can be eliminated easily.

2. Second, we are talking about people who eat mercury-fish, so any answer choice that talks about people who don't eat MF is wrong.

3. Anything that is not stated in the passage is out of scope.

Using above mentioned information and POE, we can eliminate A, B, C, and E.

D is the best among all the choices for its soft tone. But it seems a bit awkward to say that mere abundance of fish can increase the toxicity in blood stream. But this is the best available choice.

(D)
