Step-by-step explanation:
The advisory group referenced in the question seems to be one that functions within a larger organizational framework, such as a national political party or a governmental body. While the question does not specify the exact nature of the group, it does provide a description of its functions, indicating that this body provides advisory support to a National Council or national headquarters, proposes legislation, and serves as a liaison between the National Council/Headquarters and student chapters.
