Miss Universe 2010, the 59th Miss Universe pageant, was held on 23 August 2010 at Mandalay Bay Events Center in Las Vegas, Nevada, USA. Ximena Navarrete of Mexico was crowned by Stefanía Fernández of Venezuela as her successor at the end of the event. 83 contestants competed in this year.
Stefanía Fernández was the winner of the 58th Miss Universe pageant.
The content says that Ximena Navarrete won the 59th Miss Universe pageant and was the successor to Stefanía Fernández. Because a successor is the person who immediately follows another person to hold a position, Stefanía Fernández must have won the 58th Miss Universe pageant. I think the AI system was fooled because the context pertains to the 59th pageant, not the 58th.
