“The global campaign to eradicate malaria, launched in 1955, relied heavily on the spraying of DDT and the administration of chloroquine. While it achieved dramatic success in Europe, North America, and parts of East Asia, the campaign stalled and was eventually abandoned in much of sub-Saharan Africa. The failure was not due to a lack of scientific tools, but to a lack of basic health infrastructure, political instability, and the rapid evolution of resistance in both mosquitoes and parasites. In the poorest regions of the world, malaria remained a disease of underdevelopment, showing that technology alone cannot solve problems deeply rooted in social and economic inequality.”
—Adapted from a historical analysis of mid-twentieth-century global health initiatives
Based on the passage and your knowledge of world history, which of the following best explains why technological innovations in medicine did not lead to the universal eradication of infectious diseases in the late twentieth century?
- AThe complete homogenization of global culture forced communities to reject indigenous healthcare methods, which precipitated a collapse in local sanitation infrastructure.
- BThe resurgence of infectious diseases was primarily caused by a new wave of the Columbian Exchange that re-established isolation between hemispheres.
- Persistent socio-economic disparities and inadequate healthcare infrastructure in developing nations limited the reach and efficacy of new medical technologies.Cevap
- DInternational resources were diverted from vaccine distribution to fund the eco-friendly environmental programs of the Green Revolution.
