Which pandemic urged nations to reconsider their trade practices?

• A. Plague
• B. Smallpox
• C. Cholera
• D. Influenza

Answer: (C)

The main idea is how pandemics push countries to rethink how goods and people move across borders, prompting public health measures that affect trade. Cholera outbreaks across major trade routes exposed how easily the disease could spread via ships and travelers, so nations started implementing quarantine rules, sanitation checks at ports, and other border controls. These steps directly altered trade practices, timing, and costs, leading to new international norms and regulations designed to protect commerce while trying to limit disease spread. Other pandemics did influence health policy, but cholera is the clearest case where the need to manage cross-border movement and trade became a central policy concern, making it the best answer.
