The Iliad and the Odyssey were both attributed to Homer in ancient times. But these two poems differ greatly in tone and vocabulary and in certain details of the fictional world they depict. So they are almost certainly not the work of the same poet. Which one of the following statements, if true, most weakens the reasoning above? ['Both the Iliad and the Odyssey were the result of an extended process of oral composition in which many poets were involved.', 'Works known to have been written by the same modern writer are as different from each other in the respects mentioned as are the Iliad and the Odyssey.', 'Several hymns that were also attributed to Homer in ancient times differ more from the Iliad in the respects mentioned than does the Odyssey.', 'Both the Iliad and the Odyssey have come down to us in manuscripts that have suffered from minor copying errors and other textual corruptions.']
