Final answer:
Mid-twentieth-century dramatists influenced by Beijing Opera were Bertolt Brecht and Samuel Beckett, with Brecht being known for his epic theatre style.
Step-by-step explanation:
Two mid-twentieth-century dramatists from the West who were strongly influenced by Beijing Opera were Bertolt Brecht and Samuel Beckett. Therefore, the correct answer to the question is b. Brecht and Beckett. Bertolt Brecht, a German dramatist and theatre director, was known for his development of the epic theatre, which aimed to evoke a critical attitude in the audience towards the subject of the play. Brecht's work includes plays such as 'Mother Courage and Her Children' and 'The Threepenny Opera'. Samuel Beckett, an Irish playwright and novelist, is renowned for his play 'Waiting for Godot'. Although Beckett's interest in Chinese opera is not as well documented as Brecht's, both were innovative playwrights of the twentieth century who changed the landscape of Western theatre.
