Question: Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).
Try to answer this question if possible: What was the name of the first ship to use Edison's lamp?
Answer: Columbia
Question: While its fellow Canadian broadcasters converted most of their transmitters to digital by the Canadian digital television transition deadline of August 31, 2011, CBC converted only about half of the analogue transmitters in mandatory areas to digital (15 of 28 markets with CBC Television stations, and 14 of 28 markets with Television de Radio-Canada stations). Due to financial difficulties reported by the corporation, the corporation published digital transition plans for none of its analogue retransmitters in mandatory markets to be converted to digital by the deadline. Under this plan, communities that receive analogue signals by rebroadcast transmitters in mandatory markets would lose their over-the-air signals as of the deadline. Rebroadcast transmitters account for 23 of the 48 CBC and Radio-Canada transmitters in mandatory markets. Mandatory markets losing both CBC and Radio-Canada over-the-air signals include London, Ontario (metropolitan area population 457,000) and Saskatoon, Saskatchewan (metro area population 257,000). In both of those markets, the corporation's television transmitters are the only ones that were not planned to be converted to digital by the deadline.

Answer: unanswerable
Question: The Greek men's national volleyball team has won two bronze medals, one in the European Volleyball Championship and another one in the European Volleyball League, a 5th place in the Olympic Games and a 6th place in the FIVB Volleyball Men's World Championship. The Greek league, the A1 Ethniki, is considered one of the top volleyball leagues in Europe and the Greek clubs have made significant success in European competitions. Olympiacos is the most successful volleyball club in the country having won the most domestic titles and being the only Greek club to have won European titles; they have won two CEV Cups, they have been CEV Champions League runners-up twice and they have played in as many as 12 Final Fours in the European competitions, making them one of the most traditional volleyball clubs in Europe. Iraklis have also seen significant success in European competitions, having been three times runners-up of the CEV Champions League.
Try to answer this question if possible: What Greek volleyball club is the most successful in the country?
Answer: Olympiacos
Question: Due in large part to the persuasion of representative Servando Teresa de Mier, Mexico City was chosen because it was the center of the country's population and history, even though Queretaro was closer to the center geographically. The choice was official on November 18, 1824, and Congress delineated a surface area of two leagues square (8,800 acres) centered on the Zocalo. This area was then separated from the State of Mexico, forcing that state's government to move from the Palace of the Inquisition (now Museum of Mexican Medicine) in the city to Texcoco. This area did not include the population centers of the towns of Coyoacan, Xochimilco, Mexicaltzingo and Tlalpan, all of which remained as part of the State of Mexico.
Try to answer this question if possible: When was Mexico City declared the capital?
Answer:
November 18, 1824
