Here is a question about this article: In 1952, Thomas Watson, Sr., stepped down after almost 40 years at the company helm; his son, Thomas Watson, Jr., was named president. In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the FORTRAN (FORmula TRANslation) scientific programming language was developed. In 1961, Thomas J. Watson, Jr., was elected chairman of the board and Albert L. Williams became company president. The same year IBM developed the SABRE (Semi-Automatic Business-Related Environment) reservation system for American Airlines and introduced the highly successful Selectric typewriter.
What is the answer to this question: In 1956 the company demonstrated the first example of what?

Here is a question about this article: The tourism industry began in the early 19th century when foreigners visited the Alps, traveled to the bases of the mountains to enjoy the scenery, and stayed at the spa-resorts. Large hotels were built during the Belle Époque; cog-railways, built early in the 20th century, brought tourists to ever higher elevations, with the Jungfraubahn terminating at the Jungfraujoch, well above the eternal snow-line, after going through a tunnel in Eiger. During this period winter sports were slowly introduced: in 1882 the first figure skating championship was held in St. Moritz, and downhill skiing became a popular sport with English visitors early in the 20th century, as the first ski-lift was installed in 1908 above Grindelwald.
What is the answer to this question: When were large hotels built in the Alps?

So... during the Belle Époque


Here is a question about this article: A dispute during the Lausanne Congress of Supreme Councils of 1875 prompted the Grand Orient de France to commission a report by a Protestant pastor which concluded that, as Freemasonry was not a religion, it should not require a religious belief. The new constitutions read, "Its principles are absolute liberty of conscience and human solidarity", the existence of God and the immortality of the soul being struck out. It is possible that the immediate objections of the United Grand Lodge of England were at least partly motivated by the political tension between France and Britain at the time. The result was the withdrawal of recognition of the Grand Orient of France by the United Grand Lodge of England, a situation that continues today.
What is the answer to this question: What was a possible condition that made the United Grand Lodge of England withdraw it's recognition of the Grand Orient de France?

So...
