The correct answers are the following:
Rising action: Hamlet seeks to determine his uncle's guilt.
Inciting action: A ghost tell Hamlet that Claudius murdered his father.
Climax: Hamlet accidentally murders Polonius.
Falling action: Fortinbras invades Denmark.
The inciting action is the event that begins the problem in a story. Hamlet's father appears to him as a ghost and says Claudius has killed him. The rising action is a series of circumstances that create suspense and interest to the reader. Hamlet cannot kill Claudius because he is not a murderer, so he wonders what to do with him. The climax is the part of a story which reaches its highest level of tension, conflict and crisis. In the play, Hamlet kills Polonius  unintentionally - he actually means to murder Claudius. The falling action happens after the climax, when the conflic of the story resolves. After Fortinbras' invasion, Claudius sends Hamlet to war to be killed, but then he returns.
