E. I would go with E.
Superoxy doesnot add anything extra value. Tap water does the samething what superoxy does.

Premise1:- One of the limiting factors is the amount of oxygen absorbed by muscles from bloodstream
Entrepreneurs have started selling Water X, which has more oxygen than does normal water
Conclusion:- Water X is useless
Reason:- Amount of oxygen in the blood of person who is exercising is already more than the muscle cells can absorb
This is supporting the conclusion that Selling Water X is useless. We need to find an answer choice that does the same

a)Does not support the argument( this choice is only about world class athletes)
b)Accepting this as true will not mean selling Water X would be useless
c)If lungs are the only means through which oxygen can be absorbed then consumption of water X would indeed be useless
d)No one is denying this..argument itself states that lack of oxygen is one of the limiting factors...
e)If the water lost can be replaced with ordinary tap water, so be it. There is no discussion of oxygen, limiting factors....hence this is not relevant to the argument

I'll go with C

Cheers,
Unplugged

I went for C. This actually supports the conclusion the same way as the boldface does in the argument.

i will go for D.

Premise clearly says that "one of the limiting factor of the human physical performance is the amount of oxygen absorbed by muscles from bloodstream.

But the Entrepreneurs misinterpreted it and started to sell water with more dissolved oxygen.

The conclusion says that the Entrepreneurs' idea is useless. COz the less oxygen content is not the only reason for "the limiting factor of the human physical performance"

yes, agree with C

what's the function of the bold part? this part makes the water with extra O2 useless...

The only answer that makes such water useless is C

Cheers

Agree with C, however, what is wrong with E?

E does not support the conclusion. So what if the lost water can be replaced with ordinary tap water? Still, SuperOXY may be useful.
