An increase in blood flow

by BTGmoderatorDC » Thu Jan 04, 2018 6:51 am
An increase in blood flow and a reduction in the resting heart rate lower the occurrence of hypertension, also known as high blood pressure, a medical condition in which blood pressure is chronically elevated. Persistent hypertension is one of the risk factors for strokes and heart attacks. A regimen of regular walking can assist some people in greatly increasing their blood flow and significantly decreasing their resting heart rate.

Which of the following can be correctly inferred from the statements above?

A) Individuals who walk on a regular basis do not run any risk of developing hypertension.
B) Individuals who do not walk on a regular basis run a high risk of developing hypertension.
C) Walking is the most effective method for increasing blood flow and decreasing a resting heart rate.
D) A program of regular walking for some people can lower a risk factor for strokes.
E) Only regular walking is necessary to lower the risk of heart attacks.

What is wrong with Option E?

E is incorrect because of the word "only." It's possible that biking or meditation or eating healthier could decrease the risk of stroke. A regimen of regular walking isn't the only way.
D, on the other hand is air-tight. If regular walking can increase blood flow and lower the resting heart rate, and increased blood flow and a lower heart rate can reduce hypertension, which is a risk factor for stroke, then we know that regular walking must be able to lower a risk factor for stroke in some people.
