1. a play
2. a novel
3. an essay
4. a poem

Answer: a play

Explanation: Shakespeare’s famous tragedy Macbeth is based upon his life, but is not historically accurate. In the play, Macbeth and his wife murder the aged King Duncan when he comes to visit them in their castle. In reality, Macbeth killed Duncan, who was about 39, in battle, and made himself king instead.
