Which U.S. territory does not have an FFA chapter?

Guam does not have an FFA chapter, making it the correct answer to this question. The Future Farmers of America (FFA) is a national organization that promotes agricultural education and leadership development among students. While Guam is a U.S. territory, it does not have an established FFA chapter, which is indicative of the region's educational structure and the emphasis on agricultural programs.

In contrast, Puerto Rico, the Virgin Islands, and American Samoa all have active FFA chapters. These chapters engage students in various agricultural practices and provide leadership training, playing a vital role in fostering agricultural education in these territories. This difference highlights the varying levels of agricultural program development within U.S. territories and the presence, or absence, of FFA chapters in those areas.
