Input: Read this: A Turco-Mongol conqueror in Central Asia, Timur (Tamerlane), attacked the reigning Sultan Nasir-u Din Mehmud of the Tughlaq Dynasty in the north Indian city of Delhi. The Sultan's army was defeated on 17 December 1398. Timur entered Delhi and the city was sacked, destroyed, and left in ruins, after Timur's army had killed and plundered for three days and nights. He ordered the whole city to be sacked except for the sayyids, scholars, and the "other Muslims" (artists); 100,000 war prisoners were put to death in one day. The Sultanate suffered significantly from the sacking of Delhi revived briefly under the Lodi Dynasty, but it was a shadow of the former.
Question: What Turko-Mongol attacked and defeated the Sultan of Tughlaq dynasty?

Output: Timur


QUES: By about 1910,[note 1] bound collections of empty sleeves with a paperboard or leather cover, similar to a photograph album, were sold as record albums that customers could use to store their records (the term "record album" was printed on some covers). These albums came in both 10-inch and 12-inch sizes. The covers of these bound books were wider and taller than the records inside, allowing the record album to be placed on a shelf upright, like a book, suspending the fragile records above the shelf and protecting them.

What was the purpose of record album covers?
What is the answer?
ANS: protecting them


QUES: After the Lisa's announcement, John Dvorak discussed rumors of a mysterious "MacIntosh" project at Apple in February 1983. The company announced the Macintosh 128K—manufactured at an Apple factory in Fremont, California—in October 1983, followed by an 18-page brochure included with various magazines in December. The Macintosh was introduced by a US$1.5 million Ridley Scott television commercial, "1984". It most notably aired during the third quarter of Super Bowl XVIII on January 22, 1984, and is now considered a "watershed event" and a "masterpiece." Regis McKenna called the ad "more successful than the Mac itself." "1984" used an unnamed heroine to represent the coming of the Macintosh (indicated by a Picasso-style picture of the computer on her white tank top) as a means of saving humanity from the "conformity" of IBM's attempts to dominate the computer industry. The ad alludes to George Orwell's novel, Nineteen Eighty-Four, which described a dystopian future ruled by a televised "Big Brother."
What did the television commercial "1948" introduce?

ANS: unanswerable


In addition to the principal cast, Alessandro Cremona was cast as Marco Sciarra, Stephanie Sigman was cast as Estrella, and Detlef Bothe was cast as a villain for scenes shot in Austria. In February 2015 over fifteen hundred extras were hired for the pre-title sequence set in Mexico, though they were duplicated in the film, giving the effect of around ten thousand extras.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Over one hundred extras were hired for what?
Ah, so.. unanswerable


Question: A Spanish expedition was sent from Buenos Aires, organized by the Spanish governor of that city, Bruno Mauricio de Zabala. On 22 January 1724, the Spanish forced the Portuguese to abandon the location and started populating the city, initially with six families moving in from Buenos Aires and soon thereafter by families arriving from the Canary Islands who were called by the locals "guanches", "guanchos" or "canarios". There was also one significant early Italian resident by the name of Jorge Burgues.
Try to answer this question if possible: Who organized the Spanish expedition?
Answer: Bruno Mauricio de Zabala


Input: Read this: This multilevel construct is consistent with Dasmann and Lovejoy. An explicit definition consistent with this interpretation was first given in a paper by Bruce A. Wilcox commissioned by the International Union for the Conservation of Nature and Natural Resources (IUCN) for the 1982 World National Parks Conference. Wilcox's definition was "Biological diversity is the variety of life forms...at all levels of biological systems (i.e., molecular, organismic, population, species and ecosystem)...". The 1992 United Nations Earth Summit defined "biological diversity" as "the variability among living organisms from all sources, including, 'inter alia', terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems". This definition is used in the United Nations Convention on Biological Diversity.
Question: What year did the United Nations Earth Summit define "biological diversity"?

Output:
1992
