The author's conclusion is - that the exercise is more effective than taking drug.

His conclusion is based on a survey conducted on people with normal blood pressure. Since the survey results say that people who exercise regularly have normal blood pressure.

Thus author assumes that exercise will have same effect on all the people.

Thus if we doubt this assumption, author won't be able to reach to his conclusion.

Hence D. Thank You.

Let me add my 2 cents

A & D are close.

The main point of argument is the comparison between the effects of a certain drug and the effects of exercising.

The conclusion - Exercising regularly is better than the new drug

Reasons- Exercising helped 80% of normal-blood pressure patients maintain their blood-pressure level normal. Whereas the effects of the drug(only 30% to 10%) are not as good as exercising.

D is saying if high-blood pressure patients exercise regularly, 80% of them will be able to maintain their blood-pressure to normal level. That's what we need, the figure of 80%(more than 30%), to prove the conclusion.

Hi nusmavrik,

Here: cr-drug-vs-exercise-96375.html is the same question. There are two differences. First, this question's choice A is actually choice D in the other question.

Second, here, choice A uses the word "no" while the other one uses the word "few". This is an important difference. In fact, the author's reasoning does not depend on the idea that none of the high-blood pressure patients exercise regularly. The denial of "none" is "at least one". Does this argument fall apart if, say, just one patient in the high-blood pressure group exercises regularly? Nope. And choice D of this question is definitely incorrect (I explained why in the other post).

Thus, my analysis is that there is nothing among the five answer choices that this author's reasoning depends on, and this is a bad question for that reason. If you have questions about why a certain answer choice is wrong, please don't hesitate to post!

The author says that exercise is better to lower blood pressure than the drug.

B: Out of scope
C: Out of scope
E: Out of scope - If it would be an assumption, wouldn't help the author.

So we're down to A & D, which are pretty close. So let's take a look at D:

If the patients all react the same on exercise, the assumption of the author would be true. But if the exercise would increase the blood pressure of some patients, the assumption would not be true. Hence, D is the right choice.

I agree with Testluv this question is wrong.
For D, we don't need to assume "all" patients because "all" includes low-blood pressure patients too and the conclusion doesn't include low-blood pressure patients...
