In what year were there two national FFA presidents?

The correct answer is based on the historical context of the National FFA Organization's leadership. In 1942-43, the organization experienced a unique situation where there were two national presidents. This occurred because the national convention was held during World War II, which led to unusual circumstances in leadership roles. The first president, who was elected, served for part of the year, and then a second president was elected to finish the term, resulting in two presidents serving in the same year.

This event is significant in FFA history as it reflects the challenges faced by the organization during wartime and how it adapted to maintain leadership continuity and engagement among its members. Other periods mentioned do not have documentation or historical significance that indicates the presence of two presidents in a single term, making this occurrence in 1942-43 particularly notable within FFA's timeline.
