Stress is a common cause of high blood pressure. By calming their minds and thereby reducing stress, some people can lower their blood pressure. And most people can calm their minds, in turn, by engaging in exercise.

Summary
The stimulus says that stress often causes high blood pressure. Also, some people can calm their minds to lower their stress and thus reduce their blood pressure. Finally, most people can calm their minds by exercising.
In Lawgic, this looks like:
P1. calm mind -s→ lower stress -s→ lower BP
P2. exercise -m→ calm mind

Strongly Supported Conclusions
The stimulus supports the conclusion that some people can probably use exercise to lower their blood pressure.
In Lawgic, this means combining the premises listed above to look like:
P1. exercise -m→ calm mind -s→ lower stress -s→ lower BP

A
For at least some people, having lower blood pressure has at least some tendency to cause their stress levels to be reduced.
This is not supported. The stimulus tells us about a causal link where high stress can cause high blood pressure, not the other way around.
B
Most people with high blood pressure can lower their blood pressure by reducing their stress levels.
This is not supported. Reading closely, the stimulus only says that stress is a “common” cause of high blood pressure. “Common” doesn’t equate to “most.” Instead, it would be better translated as “some,” which does not support this inference.
C
Most people who do not exercise regularly have higher stress levels as a result.
This is not supported. Firstly, most people can calm their minds by exercising, but a calm mind only sometimes reduces stress—maybe less than half the time, we don’t know. Secondly, there may be other ways to calm the mind and reduce stress without exercising.
D
Engaging in exercise can directly lower one’s blood pressure.
This is not supported. The stimulus describes a very indirect mechanism for exercise to sometimes lower blood pressure: we need the intermediate steps of calm mind and stress reduction first. That’s definitely not a direct link between exercise and lower blood pressure.
E
For at least some people, engaging in exercise can cause their stress levels to be reduced.
This is strongly supported. Based on the stimulus, exercise can calm the mind, which can reduce stress, which can reduce blood pressure. None of these steps is guaranteed, but it seems very likely that at least some people make it all the way to lower blood pressure.
