Answer:
A. He has been brought in from Beverly to determine if there are witches in Salem
Step-by-step explanation:
"Reverend John Hale" was a character in "The Crucible." He was an intellectual from Beverly who was summoned by Samuel Parris to determine the existence of witches in Salem. As a spiritual doctor, he was also expected to cure those who were afflicted. He became a witness on the unfair trials of some innocent people who were accused of being witches although he also had his fair share of shortcomings.
His good intentions pushed him to seek justice. After the Salem Witch Trials in 1692, he wrote a book about his observations regarding the witch hunt and how many people feared their lives and were tormented.
