Final answer:
Chronic diseases are responsible for 70% of global deaths, with factors like lifestyle choices playing a significant role in their prevalence. The U.S. has a disease rate of 33.9%, which falls within the average range when compared to other countries. The correct option is 1.
Step-by-step explanation:
The percentage of global deaths for which chronic diseases are responsible is 70%. Chronic diseases are a major concern globally, contributing to the majority of deaths in many developed countries. Noninfectious diseases such as heart disease, stroke, diabetes, and cancer are the leading causes of death. While some aspects of these diseases are linked to genetics, many are associated with lifestyle choices, and as such, they are largely preventable.
Given the statistics provided, the average percentage affected by a specific disease across various countries ranges from 11.4 to 74.6 percent. When comparing the United States' average disease rate of 33.9 percent to these figures, it suggests that the U.S. rate is below the maximum but does not exceed the average significantly enough to be considered unusual.
