C) The study was only conducted in one city.
D) In another experiment, cancer patients who ate one or more beets per day were no more likely to recover than those who ate no beets.

I doubt OA .How can it be E. It seems to be out of scope of the CR . Is exercising regularly related in anyway to the proper diagnosis of cancer .There is no such evidence .Guys pls put in your expert comments.Also what is wrong with A.
Through elimination, I came to E.
A. Another study & flax seed oil is no way related to our conclusion.
B. This would rather strengthen as it would cancel other possibilities.
C. Experiments will always be conducted on a sample.
D. It is out of scope as it is talking about people who already have cancer.
E. May be eating beets leads the person to do move exercise and it in turn protects someone from cancer. Only option left after elimination the above four options.
