What does the exposition at the beginning of act one tell you about the events that are to follow throughout the play?

The play's exposition informs the audience of suspected witchcraft and strange illnesses. We immediately learn that Parris will withhold integral information, that Abigail has a checkered past. We are also apprised of many small problems within the community...... disagreements and accusations. Reverend Hale has been called in to investigate, to look for an unnatural cause for Betty's illness. The stage has been set for what will come..... arrests, trials, and executions (murder).
