A medical research team in France recently discovered that people with a low risk of heart disease tend to also have low stress levels. The team concluded that a healthy cardiovascular system can protect people from the stress of modern life.

The research team's conclusion depends on which of the following?

A Medical and pharmaceutical treatments of stress are more effective than psychological treatment.
B People with high stress levels are more likely to have serious heart disease than are those who have
low stress levels.
C High stress levels do not increase one's chances of suffering from heart disease.
D Other medical studies indicate that stress levels in citizens of industrialized countries have increased over the last thirty years, as the world becomes increasingly more complex and hectic.
E People without heart disease also tend to have their blood pressure within an acceptable range.

Please explain why you chose a particular answer.

This one is a question of cause and effect. Does a healthy cardiovascular system protect people from stress? Or does low stress lead to a healthy cardiovascular system and thus a decreased susceptibility to heart disease?

The argument reasons that a healthy cardiovascular system protects against stress. For this reasoning to be valid, the possibility that low stress is healthy for the heart, must be discounted.

Let’s look at (B) and (C), which are relevant to the argument.

(B) This states that stress is unhealthy for the heart, which is opposite to the conclusion.

(C) Correctly discounts the possibility that stress is a cause of heart disease, therefore strengthening the research team’s conclusion that a healthy cardiovascular system protects against stress. (The Answer).

its a causality arguments

A leads to B
the correct answer choice needs to show that if no b, then no a. or, since A causes b, then the answer needs to show that B does NOT cause A
which is states in answer choice C.

hope this helps

.

premise 1 : research team discovers that people with low heart disease risk ( lets call it A) also have low stress level ( say it B)
conclusion : healthy cardiovascular system ( A) can protect from lower stress (B) . therefore conclusion say A -> B . but what if B ( lower stress level ) lead to A (increases chances of heart disease) . Thus a correct assumption should end this possibility. This is what option C does.
