The recent construction of the chemical plant on the shores of Lake Blue has introduced a new pollutant into the water: toxidil. Toxidil first works its way into the ecosystem through the underwater plant life. These plants absorb the pollutant, which is then transmitted to the local fish population when the vegetation is ingested. Fish so tainted appear healthy, but their meat, when consumed by humans, leads to serious health problems. The population living in the vicinity of Lake Blue will undoubtedly suffer a decline in health due to the new chemical plant.

Which of the following is an assumption necessary for the author's conclusion?

(A) Other pollutants are not also detrimental to human health.

(B) The fish in Lake Blue are consumed by the people who reside nearby.

(C) The first reported incidences of fish tainted with toxidil occurred in Lake Blue, and not elsewhere within Canada or the United States.

(D) Currently, the only source of toxidil in the world is the chemical plant at Lake Blue.

(E) Banning chemical processes that produce toxidil will merely cause the owners of the chemical plant to continue these same processes in secret at Lake Blue.

Answer will clearly be (B) from the highlighted part quoted above, negating the above will result in braking the conclusion

B clearly destroys the link when negated.

Author is assuming that settlement living near Lake blue will consume the tainted fish .

Why not D

If there are other sources of pollutants then health decline will not be because of new plant.

(D) Currently, the only source of toxidil in the world is the chemical plant at Lake Blue.

(E) Banning chemical processes that produce toxidil will merely cause the owners of the chemical plant to continue these same processes in secret at Lake Blue.

The question stem is asking for an assumption.

Conclusion is :
The population living in the vicinity of Lake Blue will undoubtedly suffer a decline in health due to the new chemical plant.

This is based on the assumption that people living nearby eat the fish from that lake.
If people don't eat fish from the lake they wont get the toxin into their bodies. Negating this will shatter the conclusion.

As to why d is wrong, Pay attention to the argument structure.
We dont care of there are any other sources. If there are other sources how does that affect the conclusion.
It doesn't shatter it if there are other sources of the Toxin.

Hard and fast rule to find the correct assumption.
Negate it. if negating the assumption shatters the conclusion then its the right one.

Hope i made it clear.

Please help with my PoE:

Conclusion: The population living in the vicinity of Lake Blue will undoubtedly suffer a decline in health due to the new chemical plant.

How does author arrive here?
A recent construction of a chemical plant introduces a pollutant T in water.
T transfers to fish wide vegetation they consume. When humans consume sick fish, they
too become sick.

So people living nearby the Lake Blue will be sick due to new chemical plant.

Quote:
(B) The fish in Lake Blue are consumed by the people who reside nearby.

Negating this -> The fish in Lake Blue are NOT consumed by the people who reside nearby. Shatters the conclusion

Quote:
(D) Currently, the only source of toxidil in the world is the chemical plant at Lake Blue.

Negate this ->Currently, there are other sources toxidil in the world than the chemical plant at Lake Blue.
Then also this WEAKENS my conclusion.Since now I can not attribute sickness of people to new chemical plant.
