What constitutes an education issue in Diego's case at the academy?

In Diego's case at the academy, the issue of education is centered around the challenges he faces due to receiving little education and facing classes delivered in an unfamiliar language. This situation significantly impacts his ability to learn and integrate into the academic environment. When students struggle to understand the language of instruction, they may find it difficult to grasp core concepts, participate effectively in discussions, and complete assignments, which can hinder their overall educational development. Additionally, having limited access to educational content can thwart their academic progression and lead to feelings of isolation or frustration, which becomes particularly critical in an academy setting where a robust education is essential for personal and professional growth. The other options do not directly pertain to the fundamental issue of education being compromised due to language barriers and inadequate educational exposure.
