Question

select the correct answer.
heart disease risk factors (bar chart: y - axis “% of adults”, x - axis labels: inactive lifestyle, obesity, high blood pressure, smoking cigarettes, high cholesterol, diabetes)
the bar chart shows the percentage of adults in the u.s. living with certain heart disease risk factors. which conclusion can be drawn from the chart?
a. about 30% of adults are living with obesity, high blood pressure, or both.
b. diabetes is the leading cause of heart disease among adults who have high cholesterol.
c. over 50% of the reporting adults are living with risk factors that can be controlled through diet and exercise.
d. if an adult leads an inactive lifestyle, he has a 38% chance of getting heart disease.

Explanation:

• Option A: Obesity is ~33%, High Blood Pressure is ~30%. The "or both" part would require knowing overlap, but even without, the sum of individual is ~63%, so "about 30%" is wrong.
• Option B: The chart shows % of adults with each risk factor, not causation or relation between diabetes and high cholesterol. So this is incorrect.
• Option C: Risk factors controllable by diet/exercise: Inactive Lifestyle (~38%), Obesity (~33%), High Blood Pressure (~30%), Smoking (~20%), High Cholesterol (~15%). Adding these (even without double - counting, as a rough estimate), 38 + 33+30 + 20+15 = 136, but since it's percentages of adults, we consider the proportion. However, more simply, Inactive, Obesity, High BP, Smoking, High Cholesterol are controllable. The sum of their percentages (even if we assume no overlap, which is not true, but for estimation) is way over 50%. So this is correct.
• Option D: The chart shows % of adults with inactive lifestyle as a risk factor, not the chance of getting heart disease. So this is incorrect.

Answer:

C. Over 50% of the reporting adults are living with risk factors that can be controlled through diet and exercise
