Final answer:
The sentence contains a comma splice.
Step-by-step explanation:
The incorrect aspect of the sentence 'Japanese Noh theater is based on traditional literature, and all the actors wear masks' is that it contains a comma splice. A comma splice occurs when two complete sentences are joined by a comma without a coordinating conjunction or appropriate punctuation.
In this case, the two complete sentences are 'Japanese Noh theater is based on traditional literature' and 'all the actors wear masks.' To correct the comma splice, you can add a coordinating conjunction like 'and' or 'but' after the comma, or you can separate the sentences with a period to create two distinct sentences.
