Answer is Right!
Answer is Wrong!
The correct answer is: E. No error
The sentence is grammatically correct. The verb “has” agrees with the subject “facts,” which is plural. The conjunction “and” joins the two independent clauses “The new facts he has discovered” and “The new arguments he has advanced.” The verb “has not changed” agrees with the subject “opinion,” which is singular.
The sentence could be improved by adding a comma after “facts.” This would make it clear that the two independent clauses are separate thoughts. For example:
The new facts he has discovered, and the new arguments he has advanced, have not changed my opinion.
