A guard arrives

After Jasmine realised she was in a dungeon, she heard the door being opened, a large burly guard appeared, moved over to her undid her chains, dragged her to her feet and dragged her outside. The air was warm and she saw a large wooden structure to which there was a large man with an ax, Jasmine was terrified and tried to fight back but she was subdued her mouth gagged and slammed onto the chopping block and the man raised his ax and slammed it down.

Jasmine jumped awake and in the same position she was in about a minute or so ago and she then realised that this must be a test for something and that she had to escape, but how?
