As promised, I'm posting the ones I'm unsure of.
1) At the time when Macbeth was written there was a very public debate about witches in England. Reginald Scot, in his “Discovery of Witchcraft” argued that witches did not really exist.
2) King James took a personal interest in the subject of witchcraft and wrote a book on the subject, Demonology, as a response to Scot’s book.
3) The king believed that witches existed and secretly attended the trials of women accused of being witches.
4) His wife's arrival to Scotland was blocked by storms and James’s return to England was again threatened by storms. 5) A midwife named Agnes Sampson was accused of being a witch and having (??) tried to destroy the king. At first she rejected all the charges against her, but then after being tortured she confessed.
(she confessed to being guilty?)
1 & 2. Titles of books and plays need to be underlined or in italics.
3. OK
4. "arrival in Scotland..."
comma needed
5. "...and trying to destroy..."
(no need for words in parentheses)
