Input: Read this: 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 ete gagne la bataille de Waterloo" ("It is here that the Battle of Waterloo was won.")
Question: In what year was Edward Creasy made a Sir?

Output: unanswerable

Input: Read this: BYU's stated mission "is to assist individuals in their quest for perfection and eternal life." BYU is thus considered by its leaders to be at heart a religious institution, wherein, ideally, religious and secular education are interwoven in a way that encourages the highest standards in both areas. This weaving of the secular and the religious aspects of a religious university goes back as far as Brigham Young himself, who told Karl G. Maeser when the Church purchased the school: "I want you to remember that you ought not to teach even the alphabet or the multiplication tables without the Spirit of God."
Question: What did Karl G. Maeser tell Brigham Young?

Output: unanswerable

Input: Read this: By the late 1960s, many of the resort's once great hotels were suffering from embarrassing vacancy rates. Most of them were either shut down, converted to cheap apartments, or converted to nursing home facilities by the end of the decade. Prior to and during the advent of legalized gaming, many of these hotels were demolished. The Breakers, the Chelsea, the Brighton, the Shelburne, the Mayflower, the Traymore, and the Marlborough-Blenheim were demolished in the 1970s and 1980s. Of the many pre-casino resorts that bordered the boardwalk, only the Claridge, the Dennis, the Ritz-Carlton, and the Haddon Hall survive to this day as parts of Bally's Atlantic City, a condo complex, and Resorts Atlantic City. The old Ambassador Hotel was purchased by Ramada in 1978 and was gutted to become the Tropicana Casino and Resort Atlantic City, only reusing the steelwork of the original building. Smaller hotels off the boardwalk, such as the Madison also survived.
Question: By what years were many of the great hotels suffering from high vacancy rates?

Output:
the late 1960s
