Identify one tragedy and one comedy written by William Shakespeare.

The combination of "Macbeth" and "Much Ado About Nothing" accurately represents a tragedy and a comedy from Shakespeare's body of work. "Macbeth" is one of Shakespeare's most famous tragedies, exploring themes of ambition, guilt, and the supernatural through the story of a Scottish nobleman who descends into madness after committing murder to achieve power. The play's dark tone and tragic elements, including betrayal and moral decay, firmly categorize it as a tragedy.

On the other hand, "Much Ado About Nothing" is a well-known comedy characterized by its witty dialogue, humorous misunderstandings, and romantic entanglements. The play hinges on the themes of love, honor, and deception, culminating in a joyful resolution that is typical of Shakespearean comedies, typically involving misunderstandings that are resolved by the end.

This combination of works illustrates the range of Shakespeare's ability to tackle both serious subjects and lighthearted themes, making it a fitting choice.
