Answer :
Answer: I would contend that the right answer is the (D) the performance of the actor who plays Harlequin in La Finestrina does not serve as evidence against the director’s claim.
Explanation: Since the director’s claim is that his modern production is "as similar to the original production (18th century) as possible," and even though the performance of the actor recalls that of 20th-century American comedian Groucho Marx, the fact that Marx's comic style was actually inspired by the Italian comic acting tradition—begun in the sixteenth-century—serves to support the argument that the actor's performance cannot be used as evidence against the director’s claim. Quite the opposite, that performance, if only indirectly, supports that claim.
