Final answer:
The diversity of the American theatre scene has not led to a lack of audience support; instead, it thrives through Broadway, Off-Broadway, and over 1400 Regional Theatres, albeit with challenges like high ticket prices.
Step-by-step explanation:
The statement suggesting that the diversity of the American theatre scene has led to insufficient audience support for live theatre to sustain itself is False. Despite the challenges of high ticket prices and the environmental concerns that modern playwrights must consider, the American theatre scene is vibrant and dynamic. The theatre ecosystem in the U.S. includes not only the highly commercialized Broadway and Off-Broadway theatres, where the stakes for investors are indeed high due to the enormous production costs, but also encompasses over 1400 Regional Theatres that produce a variety of shows. These regional theatres sometimes focus on new works and have the flexibility of multiple stages, catering to diverse audiences and interests.
Musical theatre especially enjoys significant popularity, with Broadway hits demonstrating how a theatre production can achieve commercial success and attract audiences. In contrast to the commercial theatre, there's also the realm of Amateur Theatre, and historically, a variety of entertainments from touring troupes to vaudeville shows and circuses have captivated American audiences. Today's theatre allows for a transformative experience, providing escape and engagement, although the high costs of Broadway productions have been acknowledged as a barrier for some potential theatre-goers. Nonetheless, the wide range of theatrical offerings suggests that live theatre continues to be a meaningful art form with ample audience support.
