Final answer:
Farming affected the economic slowdown that led to the Great Depression through overproduction and declining prices.
Step-by-step explanation:
The statement that best explains how farming affected the economic slowdown that led to the Great Depression is: Even though prices and demand were falling, production increased. During the 1920s, advances in technology, such as large machines, made farms more efficient. However, this led to overproduction, which caused a surplus of crops and a decline in prices. As a result, farmers struggled to make a profit, contributing to the economic slowdown and ultimately the Great Depression.
