Task: Question Generation
Input (English): The Duke of Wellington is often incorrectly quoted as saying that "The Battle of Waterloo was won on the playing-fields of Eton". Wellington was at Eton from 1781 to 1784 and was to send his sons there. According to Nevill (citing the historian Sir Edward Creasy), what Wellington said, while passing an Eton cricket match many decades later, was, "There grows the stuff that won Waterloo", a remark Nevill construes as a reference to "the manly character induced by games and sport" amongst English youth generally, not a comment about Eton specifically. In 1889, Sir William Fraser conflated this uncorroborated remark with the one attributed to him by Count Charles de Montalembert's "C'est ici qu'a été gagné la bataille de Waterloo" ("It is here that the Battle of Waterloo was won.")
Output (English): What "stuff" won Waterloo, according to Wellington?
