I find this question confusing, please help.

Theater critic: The play La Finestrina now at central Theater, was written in Italy in the eighteenth century. The director claims that this production is as similar to the orignial production as is possible in a modern theater. Although the actor who plays Harlequin the clown gives a performance very reminiscent of the twentieth-century American comedian Groucho Marx, Marx's comic style was very much within the comic acting tradition that had begun in sixteenth-century Italy.

The considerations given best serve as part of an argument that:

A. Modern audiences would find it hard to tolerate certain characteristics of a historically accurate performance of an eighteenth-century play.

B. Groucho Marx once performed the part of the character Harlequin in La Finestrina

C. in the United States the training of actors in the twentieth century is based on principles that do not differ radically from those that underlay the training of actors in eighteenth- century Italy

D. the performance of the actor who plays Harlequin in La Finestrina does not serve as evidence against the director's claim.

E. the director of La Finestrina must have advised the actor who plays Harlequin to model his performance on comic performances of Groucho Marx
