What is the setting for Act I of "The Crucible"?

The setting of Act I of The Crucible is the home of Reverend Parris.  He is standing over his young daughter, Betty's bed.  She lies very still, Abigail tells the reader that the Doctor can find nothing wrong with Betty.

All the action takes place in that upstairs room.  Before long, other members of the community arrive, including Rebecca Nurse, John Proctor, Anne Putnam and Reverend Hale, who has been called to Salem by Reverend Parris. Hale is an authority on witchcraft and on helping the bewitched. 

All the action takes place in the upper room of Reverend Parris's home.  Including, the interrogation of Tituba, Reverend Parris's slave, and her confession to witchcraft.  Which is followed by Abigail Williams own admission of having signed the Devil's book.
