What are the six major events that occur in Act III of The Crucible?

There are many events that occur in Act 3 of The Crucible. If six major events must be specified, then the most important events are:

1. 
   Giles interrupts the proceedings and is eventually arrested for contempt. Giles is a character who appears predominately in the third act. An elderly man, Giles is cantankerous and loves his wife. He refuses to go along with the witchcraft hysteria and claims men are using the hysteria for their own personal economic gain.


2. 
   Mary announces she was pretending to be afflicted by witchcraft. This is a crucial moment because Mary presents a rift in the girls' narrative about witchcraft. 


3. 
   Proctor is questioned about his religious beliefs. Proctor is continuously examined by the court in this act. While many are put on trial, the audience mostly sees the court through Proctor's experience. 


4. 
   The girls accuse Mary of witchcraft and proceed to be "bewitched" by Mary's spirit. The girls quickly turn on Mary and claim she has possessed them. Mary attempts to stop the girls but eventually joins their hysteria in fear. 


5. 
   Elizabeth admits Proctor committed adultery with Abigail. Elizabeth looks to Proctor for signs but ultimately admits he confessed to this sin.   
   


6. 
   Hale denounces the proceedings. Throughout the act, Hale is increasingly critical of Danforth and the proceedings. By the end of the act, Hale exits the stage and declares he is quitting the court.
