Explanation:

The Columbian Exchange involved the transfer of plants, animals, and goods between the Old World and the New World. Disease spread (negative), forced European culture (negative), and the start of the Atlantic Slave Trade (negative) are all negative outcomes. New foods being exchanged (e.g., potatoes from the Americas to Europe, which helped with food security) is a positive outcome.
