Will she get the job. Will he tell the truth. Will they get out. The question has to be answerable and it has to be asked early, because attention through a middle section is a function of an unanswered question rather than of how interesting the middle is.
A piece can have exactly one central question. It can have many subordinate ones, and it usually should, but if two questions compete for the central position the audience does not know what they are waiting for and the ending answers something they had stopped tracking.
The commercial test is quick: state your piece’s question in one sentence beginning "will". If you cannot, the piece is a presentation. That is sometimes the right thing to make, but it will be watched the way presentations are watched.
What is the dramatic question?
The yes-or-no question a story poses early and answers at the climax. It is the mechanism that holds attention through a middle section, which is why a piece without one drags regardless of how good its parts are.
Can a story have more than one dramatic question?
It can have many subordinate questions but only one central one. Two competing central questions leave an audience unsure what they are waiting for, and the ending then resolves something they stopped tracking.
