Can somebody explain why B is not stronger than A here in regard to undermining the conclusion?

Thanks in advance


Pharmacist have found that people who wear contact lenses buy soothing eye drops to manage dry eyes more than people who do not wear contact lenses. Pharmacist assume that wearing contact lenses cause dry eyes.

We want to undermine this conclusion. So What could be other possible explanation?

Possibly, if there is an inherent condition wwhich causes BOTH--> Dry Eyes and poor eysight --> Patients will require both eye drops and contact lenses, in such a case, contact lenses DO NOT CAUSE eye dryness, Still patients will require soothing eye drops.
So A is plausible explanation which can undermine above conclusion.

Now consider B:
Physical exertion causes dry eyes in many people who wear contact lenses.
We dont know, whether people are actually exercising after wearing contacts, so even if the info in B was true, we wont be able to attribute the dryness to contact lenses.

I hope this helps. Experts may provide alternate explanation.

The problem in these questions is to identity what is causing what. If you have to weaken a question like this, here is what you do.

Let say A clause B, typical question will give you an answer choice in which b will cause A and that will be the answer.
similary, if A causes b, then find something where C is clausing B, which clearly refutes the argument.

For example

Contact lens causes dryness.
Ok.
but one of the answer says, no, there is another disease, that causes both. And guess what, whole argument fell apart. This is exactly what happened here.


Hi riteshgupta1

Isn't option A making a logical jump by assuming that only people with weak eyes can wear lenses.


Actually No,

A says that there is another reason for both the circumstances to coexist. and this reason undermines the conclusion of the pharmacists that contact lenses are causing eye dryness.

I can understand when you are saying that both the things are caused by a third factor. But my point is that those two things discussed in option choices and question stimulus are different.

So, when does question states that people with weak eyes wear lenses. What if now people wear lenses only for cosmetic purposes. So, in the given question it is assumed from the reader that he should know that the lenses are worn as a matter of eye defect.
