Stimulus

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 turn, by engaging in exercise.

What this question is testing

Most Supported

Facts

Three pieces of information:

1. Stress causes high blood pressure (often).

2. Calming the mind reduces stress; for some people this lowers their blood pressure.

3. Most people calm their minds by exercising.

Evaluate

Most Supported questions reward small, careful inferences. The safest move chains the closest links. Most people can calm their minds by exercising. Calming reduces stress. So at least some people — those covered by "most" — get their stress reduced by exercising.

Watch out for answers that go too far: claiming exercise directly lowers blood pressure (skips the chain), or claiming most people can lower their blood pressure this way (the stimulus only says "some" can).

Goal

Pick the answer that's a small, conservative inference: at least some people get stress reduction from exercise.

Which one of the following is most strongly supported by the

Answer choices

  1. Reversal / Negation2% picked this

    For at least some people, having lower blood pressure has at least some tendency to cause their stress

    The stimulus says reducing stress lowers blood pressure for some — the direction is stress → blood pressure. This answer reverses it, claiming lower blood pressure causes lower stress. Nothing in the stimulus supports that backwards causal direction.

  2. Too Strong9% picked this

    Most people with high blood pressure can lower their blood pressure by reducing

    The stimulus says "some people can lower their blood pressure" by reducing stress — not most. So we can't conclude that most people with high blood pressure can lower it through stress reduction. The leap from "some" to "most" is unsupported.

  3. Too Strong3% picked this

    Most people who do not exercise regularly have higher stress levels

    The stimulus says exercise can calm the mind for most people — but it doesn't say that not exercising causes higher stress. People who don't exercise might use other ways to calm their minds. So claiming non-exercisers have higher stress as a result is unsupported.

  4. Too Strong10% picked this

    Engaging in exercise can directly lower one's

    The stimulus describes an indirect chain: exercise → calmer mind → reduced stress → lower blood pressure (for some). This answer says exercise can directly lower blood pressure — skipping all the intermediate steps. The stimulus doesn't support a direct mechanism; it supports an indirect one routed through stress.

  5. Correct75% picked this

    For at least some people, engaging in exercise can cause their stress levels

    Why this is right

    This is the conservative inference the chain supports. The stimulus says (a) calming the mind reduces stress and (b) most people can calm their minds by exercising. So at least some of those "most people" have their stress reduced by exercising. The "for at least some" hedge keeps the inference safely within what the stimulus guarantees.
