Which officer is responsible for building school and community support for the agricultural program?

The role of the advisor in an agricultural program, particularly within organizations like FFA (Future Farmers of America), is crucial for fostering support both within the school and the broader community. Advisors serve as mentors and guides, helping students navigate their projects and initiatives. They often have established relationships with community stakeholders and can leverage these connections to build support for the agricultural program.

An advisor's responsibilities typically include engaging with community members, organizing events that showcase student work, and promoting the program's impact and benefits to the public. Through these actions, the advisor plays a key role in highlighting the significance of agriculture education and securing resources or partnerships that benefit the program and its students.

The other roles, such as president, secretary, and treasurer, focus on leadership tasks, administrative duties, and managing finances, respectively. While these positions are essential for the internal functioning of the organization, the advisor's role is specifically tailored towards external relationship-building and advocacy, making them the correct choice for this question.
