What is the tone in each one of the Acts?

ACT I - SUSPICION and HYSTERIA: Everyone wonders what the
girls were doing out in the woods, while the girls wonder what they can do or say to not
get caught. They frantically work on a plan when they are out of the earshot of adults.
The adults worry what great demonic affliction is bearing down in their
midst.

ACT II - CONTEMPT: Elizabeth treats John with
judgement although it seems she doesn't want to. The authorities test and question the
merit of John and Elizabeth's faith, and John tests the loyalty of Mary
Warren.

ACT III - GROWING SCORN: Accusations continue to
fly and those who would not have questioned each other in previous circumstances now do
so. The effort to produce truths grows and many characters achieve this
ineffectively.

ACT IV - COMPLETE MADNESS: This crazed
society is in complete control by the magistrates who have in previous acts relied on
the testimony of children who reported false facts. Their effort goes to such great
lengths to do what is right that they do what is wrong and we as an audience can see the
absurdity of their acts, but the characters invested in the play have no idea how
entrenched they have become in the lies they live.
