Answer:
Hamlet is shocked because Claudius's reaction to the play clearly shows his guilt.
Explanation:
According to the excerpt from Hamlet, Hamlet cleverly stages a play that shows a brother killing his brother to take the throne, to mirror the actions of his uncle Claudius on his quest to become king. 
During the course of the play, King Claudius becomes uncomfortable and leaves the play and Hamlet is shocked because he was not sure the ghost's accusations were true but now it has been proven beyond all doubt. 
 
        
             
        
        
        
Your instrument, outside of music, is your own voice. If you love yourself and tell the world (using your 'instrument'), then you can feel fulfilled. This advice is good for anyone who feels like they aren't heard or seen, they can use their voice to speak up and create change for themselves and others.

The murder of JonBenét Ramsey is the first thing that popped up in my mind of unsolved mystery and murder cases. she was a young girl, only 6 years old. her family was incredibly wealthy and everything seemed normal. people still talk about her case to this day because everything about it was so odd and explanations didn’t add up, also most people think that her brother or other family members committed the crime. dont know much ab this case but i just remember watching videos on it when i was younger
