Final answer:
The Smith-Hughes National Vocational Education Act of 1917 was instrumental in establishing courses in vocational agriculture that led to the creation of the National FFA Organization.
Step-by-step explanation:
The original idea for the National FFA Organization was fostered after courses in vocational agriculture were established by the Smith-Hughes National Vocational Education Act in 1917. This act was a critical step in promoting vocational education in agriculture, which ultimately led to the establishment of organizations like the Future Farmers of America, now known as the National FFA Organization, to support young people interested in agricultural careers. The Morrill Act of 1862 also played a significant role in this development, as it provided for the creation of land-grant colleges to offer practical degree programs, including those in agriculture, which further enhanced the educational infrastructure that the National FFA Organization would build upon.
