B is the trap answer for those who don`t understand the word benign (no effect).

The cleaner water creates a favorable enviornment for Pike to flourish. The pike`s prey are the sunfish, and hence their voracious eating habits have resulted in dwindling sunfish numbers. (C) clearly resolves the paradox.

shahnandan · Answer

clear (C). The refinment process has given rise to the predator which is responsible for dwindling sunfish population.

OasisNYK · Answer

I had a tougher time with this one...it looks like it is between A and C for sure - and while C looks like it is the right answer, it does not say that pike is a specific predator of sun fish unless it is stating it is a predator of all fish - in which case it would be correct.

A on the other hand looks like it would reduce the number of fish in the population because while the water has become cleaner, it is still polluted a little and this causes there to be less offspring, thus reducing the population.

I chose A but I would not be overly confident that it is correct. OA?

old_dream_1976 · Answer

here is my take on why not A 

we are talking about a period 1 year max . My gold fish is with me for more than a year. and i bought him when he was about 2 inches long now he is 2 1/4 inc.

we are talking about decrease not decrease in growth.

ps_dahiya · Answer

C it is.

I also had a problem with these CRs but not now. I used to think cause of a cause. I mean thinking to far.
If you are inclined towards A then you might be thinking that more pollution ----> less offsprings ------> reduce population.
Less offsprings doesn't mean less population but it says less population growth.

Juaz · Answer

Between A and C, C is better choice.

jaynayak · Answer

Clear winner C

If the predator fish that feeds on the sunfish increase. It can account for the dwindling population of sunfish

Gauss · Answer

in this case there is a close call between C and D but I would say D because it more directly address the new clining policy while C is more a consequence of the porcess

dwivedys · Answer

Did we get an OA on this C. I chose C as well.

rnachloo · Answer

C

I see that we are discussing if A could be the answer? Doesn't A state the contrary. I think it says "if pollution is high, life span doesnt come down, by the number of offspring production during their life span comes down".

If this were true, the population of this particular fish should increase and not decrease?

Am I missing anything here.

gmatornot · Answer

Got stuck between A & C but went with C finally (however note that it does not say that pike, the predator fish are actually in the lake)
