Boards of trades were established in the second half of the 19th century at locations around which river?

• A. Missouri River
• B. Mississippi River
• C. Colorado River
• D. Ohio River

Answer: (B)

Boards of trade arose to bring order to heavy agricultural markets by standardizing contracts, enabling price discovery, and managing risk for farmers and merchants. The Mississippi River corridor served as the main inland trade highway in the 19th century, linking vast Midwest production with river ports and external markets. This made river towns along the Mississippi natural centers for these exchanges, where farmers could hedge and traders could set standardized terms for commodities moving along the river system. While other rivers were important to regional trade, the Mississippi provided the broad, integrated network that these boards of trade capitalized on.
