Kublai Khan is the grandchild of Genghis Khan?
Explanation
The statement is false. Kublai Khan was not the grandchild of Genghis Khan; rather, he was the grandson. Kublai Khan was the fifth Khagan (Great Khan) of the Mongol Empire and the founder of the Yuan Dynasty in China. He was the grandson of Genghis Khan through his son Tolui, who was Genghis Khan's fourth son. Therefore, the correct statement would be: Kublai Khan is the grandson of Genghis Khan.
