Better sanitation and nutrition generally resulted from the?

The correct answer relates to the Medical Revolution, which encompasses improvements in medical science, public health practices, and overall healthcare delivery that significantly impacted sanitation and nutrition. This period saw advancements such as the development of vaccines, antibiotics, and better understanding of hygiene, which greatly reduced mortality rates and improved life expectancy. These improvements also led to better health outcomes for populations, as infectious diseases were less likely to spread in well-sanitized environments, and people had access to essential nutrients through better food production and distribution.

In contrast, while the Environmental Revolution focuses on sustainable practices and awareness of ecological impacts, it does not directly address the immediate improvements in sanitation and nutrition. The Green Revolution pertains specifically to agricultural advancements that increased food production and helped combat hunger, but it does not encompass the broader medical advancements that had a significant effect on public health in a comprehensive sense. The Industrial Revolution primarily altered production processes and economic structures, leading to urbanization and changes in labor, but it also had indirect effects on sanitation and nutrition through the rise of factories and urban living conditions, which introduced new public health challenges rather than directly addressing sanitation improvements.
