It is widely known that oxidants are toxic in large amounts, and our cells naturally generate their own anti-oxidants to neutralize them. Accordingly it is advised that people boost the intake of antioxidants to counter the effects of toxic "reactive oxygen species," or ROS, the elevated levels of which are connected with various cancers. However, such advice may not have any substantial medical grounds as new research shows that tumor-promoting ROS are produced at cellular energy factories called mitochondria whereas supplements and dietary antioxidants tend to accumulate at scattered distant sites in the cell not connected with mitochondria at all.
In the argument above, the two bold-face portions play which of the following roles?
(A)The first is a conclusion against the position taken by the argument; the second acts as evidence in support of that position.
(B)The first is evidence that the argument disputes; the second is an observation that supports the main conclusion drawn by the argument
(C)The first acts as evidence against the position taken by the argument; the second acts as a reason in support of the position taken by the author
(D)The first is a conclusion that is disputed by the argument; the second is evidence that supports that conclusion
(E)The first is a conclusion that the argument as a whole disputes; the second is evidence that supports the position taken by the argument.
