Final answer:
The crop brought by Europeans to the New World was wheat, as crops such as cacao, potatoes, and tomatoes were native to the Americas. Wheat was vital for European rituals and culinary practices in the New World.
Step-by-step explanation:
The crop that Europeans brought to the New World was wheat. This is because crops like cacao, potatoes, and tomatoes originated in the Americas, a fact which is well-documented in historical accounts of the Columbian Exchange. The Europeans introduced wheat to the Americas, which was crucial for their culinary practices and religious rituals like the making of communion wafers for the Roman Catholic mass. Crops native to the Americas such as potatoes, maize (corn), and tobacco became staples in Europe, profoundly affecting European diets and economies. On the other hand, crops like sugarcane were brought to the Americas by Europeans, changing the agricultural landscapes of the New World.
