Student , this is a prediction question, meaning you are allowed to speculate, or make your best guess. What do you think of when you hear the words "dangerous" and "game," for instance? Different pictures may come to mind, such as fire or sports, but in the end, when a teacher asks you to "predict" something, whatever you feel might happen is your best answer.
In this case, one might predict that the characters are going to engage in a competition that is hazardous, even fatal. If you have not yet read the story, there is no way you will know just what that competition is, therefore, feel free to offer your own opinion within your answer.
