“In the latter half of the twentieth century, the containment of classic infectious killers like pneumonia, tuberculosis, and gastroenteritis shifted the demographic profile of middle- and high-income nations. With the widespread adoption of public sanitation, antibiotics, and immunization programs, human life expectancy rose significantly. However, this demographic shift unveiled a new epidemiological regime dominated by chronic, non-communicable conditions. Diseases of lifestyle and aging—such as ischemic heart disease, stroke, and various forms of cancer—became the leading causes of mortality. These conditions, unlike their infectious predecessors, require long-term management rather than short-term cures, reflecting both the triumph of modern medicine in extending life and the limits of technology in eradicating the biological wear of aging.”
Based on the passage and your knowledge of world history, which of the following best describes the historical relationship between technological progress and global disease patterns in the twentieth century?
- AGlobal medical integration led to complete cultural and economic homogenization, eliminating regional differences in healthcare access and disease distribution.
- Increased life expectancy led to a shift in mortality patterns, making chronic diseases associated with aging more prevalent.Answer
- CTechnological developments in medicine sparked the Green Revolution, which was primarily an environmentalist movement focused on reducing industrial waste.
- DGlobal health crises forced Western powers to establish direct colonial administrations over sovereign developing nations to manage sanitation.
