Explanation:

The four errors are corrected because according to the functions of comma, a comma is used to separate ideas in a sentence and the first incorrect comma was removed because it was separating the same idea in a sentence.

The second error was as a result of omitting a comma after writing "Don Roth" as it is used to separate the receiver of the action from the rest of the sentence.

The third error was as a result of adding a comma before the indirect quotation.

The fourth error was as a result of adding an inappropriate comma in the sentence with the same idea.
