In which city was the first FFA-owned National Headquarters located?

The first FFA-owned National Headquarters was established in Alexandria, Virginia. This location was significant because it represented the initial centralized offices for the organization as it grew and developed after its founding in 1928. Alexandria serves as a historical touchpoint for the FFA, marking a period when the organization was solidifying its structure and expanding its influence in agricultural education across the United States.

In contrast, Washington, D.C., while a prominent city for political activities, was not the site of the FFA's original headquarters. Austin, Texas, is often recognized for its connection to agricultural education and policy but did not serve as the FFA headquarters. Indianapolis, Indiana, became the headquarters later but was not the first location. Thus, Alexandria, Virginia, is the correct answer as it denotes the early foundation and formalization of the FFA's operations.
