What was the main purpose of the Farm Bill passed in 1990?

The primary focus of the Farm Bill passed in 1990 was indeed to require the U.S. Department of Agriculture (USDA) to issue regulations for Electronic Benefit Transfer (EBT) as a food stamp delivery option. This marked a significant shift in the way food assistance programs were administered, transitioning from paper coupons to electronic systems, which aimed to streamline access for beneficiaries and enhance the efficiency of food stamp distributions. The adoption of EBT helped ensure that recipients could access benefits more easily while improving accountability and reducing fraud in the system.

The other options, while relevant to discussions of agricultural policy, do not accurately reflect the primary goal of the 1990 Farm Bill as it was specifically aimed at modernizing food assistance through EBT. International agricultural trade regulation, farmer subsidies, and sustainable farming practices were also considerations in various legislative contexts, but the establishment of EBT regulations stands out as the crucial innovation driven by the 1990 bill.
