### Reflection on Hypotheses  
**H1:**: _How Can an XR-Based Virtual Educator Be Designed and Implemented in a Serious Game?_  
The adoption of a \"serious games\" approach is justified by its ability to combine education and immersive interaction, allowing complex concepts like agricultural management to be taught in a more effective and engaging way. This approach provides a safe environment where users can experiment and learn without real-world consequences, simulating complex systems in a cost-effective and scalable manner. Additionally, it promotes knowledge retention by actively engaging users and adapting to different learning styles, making it easier to understand agricultural techniques through virtual experimentation [64; 65; 66].  
By designing a reference architecture depicting the system's overall functionalities in the high hierarchy as well as future recommendations and improvements of a designed new system. In addition, a set of proofs of concept was developed next to the reference architecture. These contained an interactive NPC agent educator in various XR virtualized agricultural educational setups. The avatar was designed based on stakeholders' needs in the domain under study and equipped with general knowledge regarding various technologically disruptive sustainable cultivation practices for various crops. Implementing the virtual educator in a serious agricultural game at the time of conducting the research and development was considered a novel approach, while non-relevant research was conducted before for the domain understudy.
**H2:**: _What Is the Future of the Integration of XR and AI Agricultural Education?_  
The future integration of XR in agricultural education has the potential for disruptive transformation of skill development modules. XR can provide immersive and intuitive experiences simulating real farming scenarios without the need for natural resources and physical farm trips. It fosters remote learning, allowing students from various locations around the globe access to advanced hands-on education. In addition, XR applications that introduce AI-driven virtual educators or NPCs can help students or farmers capture the knowledge of various complex subjects in real time. As more technological advancements are implemented in the domain of disruptive technologies, XR may also find integration with precision farming tools, offering a tangible research tool for the implementation of sustainable agricultural practices.
**H3:**: _How Can Stakeholders' Concerns Be Integrated into a Platform?_  
Stakeholders' concerns were integrated into the platform by conducting a detailed survey among farmers, the main stakeholders in this research. The survey collected important information about their experience with agricultural technologies, their willingness to adopt these tools, and their familiarity with them. It also assessed whether farmers recognized the potential for such technologies in their fields and were open to trying them. The results provided critical insights into their concerns, which were incorporated into the platform's development, ensuring it was tailored to meet their specific needs and expectations.
