A certain drug, when taken by patients with high blood pressures, was found to lower the blood pressure to high-normal levels, or from an average of 30 percent to an average of 10 percent above normal. However a survey of patients with normal blood pressures found that almost 80 percent exercised atleast 5 days per week for 30 minutes and maintained a normal blood pressure.
Therefore, the drug is not as affective in reducing blood pressure in patients with high blood pressure as is exercise. The validity of the above conclusion depends on the truth of which of the following ?
A.None of the patients with high blood pressure exercise regularly.
B. No patient with high blood pressure successfully achieved below-normal levels with drug alone.
C. Patients with normal blood-pressure maintained healthy diets for the duration of the study.
D. Daily exercise has the same effect on the blood pressures in all patients.
E. The drug has little or no effects on patients with normal blood pressures.
