Hi @ Anna, thanks for your post. Let's start, as always, with a careful assessment of the stimulus.
This stimulus does not present an argument; rather, we get a set of facts, as follows: (1) Stress is a common cause of high blood pressure (2) By calming their minds and thus reducing stress, some people can lower their blood pressure (3) And most people can calm their minds, in turn, by engaging in exercise
The question stem asks us to identify the answer choice that is textually supported by this information.
Answer choice (E) is correct. We know that at least some people are able to calm their minds and reduce their stress; we also know that most people who can calm their minds can do so by exercising. Thus, (E) is textually supported by the information presented in the stimulus. (Remember that the word "some" means "at least one," and the word "most" means more than half.)
Answer choice (B) is incorrect because we don't have enough information to know anything about "most people with high blood pressure." This is a specific population and it is not addressed by the information in the stimulus. We only know about "some people who can calm their minds" and that most of THOSE people can do so via exercise.
Hope this helps. Please let us know if you have any additional questions
