Final answer:
A serious play that deals with significant questions of human existence is known as a tragedy. This genre, exemplified by Arthur Miller's Death of a Salesman, uses real-life issues to connect with the audience on a more personal level.
Step-by-step explanation:
A serious play that emphasizes serious questions about a man's existence is called a tragedy. Tragedy is a genre with deep historical roots that dates back to ancient Greek drama. It explores human frailty and ethical dilemmas, often leading to disastrous outcomes due to a character's fatal flaw or the cruel twist of fate. Modern tragedies, also known as dramas, introduce a sense of realism, bringing the action closer to the everyday experiences of the audience. For example, Arthur Miller's Death of a Salesman, highlights the demise of the American dream through the life of the common man Willy Loman, rather than focusing on nobility or royalty. This move towards realism and commonality allows the audience to relate more personally to the issues presented on stage.
