Using new detection techniques, researchers have found trace amounts of various medicinal substances in lakes and rivers. Taken in large quantities, these substances could have serious health effects, but they are present in quantities far too low to cause any physiological response in people who drink the water or bathe in it. Nevertheless, medical experts contend that eliminating these trace amounts from the water will have public health benefits, since ____________.

A. Some of the medicinal substances found in lakes and rivers are harmless to humans in large quantities.
B. Some of the medicinal substances found in lakes and rivers can counteract possible harmful effects of other such substances found there.
C. People who develop undesirable side effects when being treated with medicines that contain these substances generally have their treatment changed
D. Most medicinal substances that reach lakes or rivers rapidly break down into harmless substances
E. Disease-causing bacteria exposed to low concentrations of certain medicinal substances can become resistant to them.


Here we have to choose the option which supports that removing medicinal substances from water will NOT have medical benefits

why option (B) is wrong and What is the explanation of correct answer

You've got it the other way round. You must choose the option that helps to establish that eliminating these substances from the water WILL have health benefits.

(B) provides an argument to let the substances stay, i.e. not remove them. Exactly the opposite of what we are looking for. Irrelevant.
(E) provides a clear explanation for why removing these substances will have health benefits.

Therefore (E) is correct.

C is incorrect because it has nothing to do with what we want here; basically we are searching for the information that conveys that even these small traces are harmful and hence deserves to be removed; C talks off the topic E properly identifies the required information supporting what we wanted.

Hope this helps..!!

Using new detection techniques, researchers have found trace amounts of various medicinal substances in lakes and rivers. Taken in large quantities, these substances could have serious health effects, but


Situation 1- they are present in quantities far too low to cause any physiological response in people who drink the water or bathe in it.

Situation 2 - Nevertheless, medical experts contend that eliminating these trace amounts from the water will have public health benefits

We need to find the solution which will resolve the paradox.

A. Some of the medicinal substances found in lakes and rivers are harmless to humans in large quantities. I incorrect . It simply states the premise
B. Some of the medicinal substances found in lakes and rivers can counteract possible harmful effects of other such substances found there. incorrect. Read carefully, mediccal substance counter other such substance. which is out of scope,and does not resolve the paradox
C. People who develop undesirable side effects when being treated with medicines that contain these substances generally have their treatment changed incorrect. it does not explain how eliminating these will have health benefits
D. Most medicinal substances that reach lakes or rivers rapidly break down into harmless substances incorrect, it weaken the Situation 2
E. Disease-causing bacteria exposed to low concentrations of certain medicinal substances can become resistant to them. Correct. this clearly mention how eliminating these substance will have health benefits. At the same time it question the validity of situation. Therefore, it clearly resolve the paradox.

Conclusion: eliminating these trace amounts from the water will have public health benefits
Answer choice : Should strengthen the conclusion

A. Some of the medicinal substances found in lakes and rivers are harmless to humans in large quantities.
Not related. On the contrary this negates the premise stated in the argument.
B. Some of the medicinal substances found in lakes and rivers can counteract possible harmful effects of other such substances found there.
This says that having these substances is beneficial because they counteract possible harmful effects of other substances.
Leaving out these substances actually weakens the conclusion (since conclusion is to eliminate these trace amounts)

C. People who develop undesirable side effects when being treated with medicines that contain these substances generally have their treatment changed
We can say that this is already known from the argument since large quantities pose serious health effects. This choice continues further to say that if medicines have large amount then the treatment needs to be changed as they post serious health effects
D. Most medicinal substances that reach lakes or rivers rapidly break down into harmless substances
This also weakens the conclusion, because, if the trace amounts breakdown and become harmless, then there is no need to eliminate
E. Disease-causing bacteria exposed to low concentrations of certain medicinal substances can become resistant to them.
If disease causing bacteria becomes resistant, then there will be health risks to the public. This is because at the moment these trace amounts are killing the bacteria and hence are not a problem now. If not eliminated, might make the bacteria resistant resulting in health issues. Hence strengthens the conclusion.

Thanks
