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?
Smartly written passage :
Conclusion : Healthy heart can protect against stress (in general). No mention of low stress or high stress.
Premise : People with low risk of heart disease have low stress.
See the jump from "low stress" to "no stress" in general.
If we can prove that any kind of stress doesn't lead to heart disease, we can say conclusion is true.
A, C, E are non relevant.
B. This shows that low stress, not that likely but in few cases, may lead to unhealthy heart. No supporting our cause.
C. High stress don't increase chances of heart disease. Bingo. It covers low, medium, high all types of stresses.
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.
