Final answer:
The crop that most enslaved laborers in the Americas were used to grow was sugar, specifically for the production on sugar plantations in the Caribbean and Brazil.
Step-by-step explanation:
The crop that most enslaved laborers in the Americas were used to grow was sugar. During the colonial era, sugar plantations required extensive labor to cultivate and process the cane, and were a primary reason for the development of the Transatlantic slave trade. Historically, these plantations were established in various parts of the Americas, most notably in the Caribbean and Brazil, where the climate was suitable for growing sugar cane. Enslavement for sugar production was common due to the labor-intensive nature of sugar cultivation and processing, which required a large workforce. Over time, the brutal conditions and high demand for sugar led to an increase in the number of enslaved individuals brought to work on these plantations.
