I choose E as the correct answer, but what is wrong with A?

Hi Tyler808, The difference between A and E is that A is descriptive, while E is prescriptive. A simply states a fact (or perhaps an opinion), that X has Y effect. E tells us what we should do, that is, If X does Y, we should do X. Since the doctor is saying that we should tax it, the main point is prescriptive, not simply descriptive like A.

That's what I figured. Because A was factual, thus we don't know 100%. Thank you Emil!

I am very confused with this description. I choose A and it is correct, but this description here in the message board is saying that A is wrong and E is correct. Please clarify. In my section, A is saying "Taxing junk food would benefit public health."

Looks like I flipped e and a!
