What does it indicate when Linda is on the point of serving lunch?

When Linda is described as being on the point of serving lunch, it implies that she is in the final stages of preparation and is ready to begin serving the meal very soon. This phrase indicates immediacy and readiness, suggesting that she is set to deliver the lunch right away rather than having just started to prepare it, waiting for a guest, or having completed all cooking processes.

The context highlights that Linda is actively in the process of serving, which emphasizes her readiness. "On the point of" typically conveys that action is anticipated to happen shortly, confirming that she will soon be serving the lunch. This makes the choice that asserts she is preparing to serve lunch shortly the most fitting interpretation of the phrase.
