Final Answer:
During the first half of the nineteenth century, the agricultural product that primarily drove the US economy was 1 Cotton.
Step-by-step explanation:
Cotton Boom: The correct answer is Cotton (Option 1) because during the first half of the nineteenth century, especially in the Southern United States, there was a significant boom in cotton production. This was fueled by the invention of the cotton gin by Eli Whitney in 1793, which revolutionized cotton processing, making it more profitable.
Economic Impact: Cotton became a major cash crop, and its cultivation and export had a profound impact on the Southern economy. The Southern states, known as the Cotton Belt, became economically reliant on cotton production and export.
Slave Labor: The demand for cotton led to the expansion of plantation agriculture, which, in turn, increased the reliance on slave labor. This economic model, known as the Cotton Kingdom, played a pivotal role in shaping the socio-economic landscape of the Southern United States.
Global Influence: The export of cotton had a global impact, as the Southern states became a crucial supplier of cotton to the international market, particularly to the textile industries in Britain and other European countries.
