Final answer:
To correct punctuation errors, you must identify if the semicolon is incorrectly separating phrases or if two independent clauses need to be connected properly. The correct action depends on the actual structure of the sentence in question. Common comma errors include using commas when a semicolon or conjunction should be used instead.
Therefore, option A is correct.
Step-by-step explanation:
To correct the error in punctuation, one should follow guideline 13.3 from the reference material, which focuses on the proper use of commas and semicolons. Common comma errors include using a comma to connect two independent clauses, which should instead be connected with a period, semicolon, or a coordinating conjunction.
In the case of the sentence provided, the correct punctuation would depend on the context of the sentence given. For example, a semicolon is used to connect two independent clauses that are closely related, and a comma should not separate a subject or verb. Advance the sentence, if the semicolon is incorrectly separating phrases instead of independent clauses, it should be removed (Option A). If the sentence contains two independent clauses, it may be necessary to add a coordinating conjunction after the comma (Option D). Removing the comma after George (Option C) would only be correct if George is not followed by an independent clause.
With the exact sentence, it is challenging to provide a definitive answer. However, in most cases a misplaced semicolon is either removed, or the sentence is restructured to include a necessary coordinating conjunction or dash.
