Questions & Answers about La gasto demandas, ĉu la mapo montras la plej mallongan vojon al la biblioteko.
Ĉu introduces a yes–no question (a question whose answer is “yes” or “no”).
In a direct question:
- Ĉu la mapo montras la plej mallongan vojon? – Does the map show the shortest way?
In your sentence, the question is indirect (embedded under demandas “asks”), so ĉu still marks that what follows is a yes–no question:
- La gasto demandas, ĉu… – The guest asks whether…
So: ĉu here = whether / if (in the sense of a yes–no question).
Esperanto normally uses a comma to separate a main clause from a following subordinate clause:
- Main clause: La gasto demandas
- Subordinate clause (indirect question): ĉu la mapo montras la plej mallongan vojon al la biblioteko
The comma is similar to English:
- The guest asks, whether the map shows…
So the comma marks the boundary between what the guest does (asks) and what exactly is being asked (the clause introduced by ĉu).
