LR Question 6 Explanation

QUESTION TEXT: Medical columnist: Some doctors recommend taking vitamin…

QUESTION TYPE: Paradox

PARADOX: Some doctors tell cancer patients not to take vitamin C, even though vitamin C has beneficial effects.

ANALYSIS: The doctors are telling cancer patients to stop taking vitamin C. This suggests there is harm from taking it.

Three of the wrong answers just show that vitamin C doesn’t help. That doesn’t resolve the paradox. Only answer choice A explains why vitamin C is harmful to cancer patients.

___________

1. CORRECT. This shows that vitamin C helps cancer cells survive treatment. That’s bad.
2. This just shows that vitamin C has no benefit. It doesn’t show that it’s harmful and that patients should stop taking it.
3. Same as B.
4. This adds to the paradox. Vitamin C can improve health, so why not take it? This advice recommends being in the best of health.
5. Same as B and C.
