Input: Tristan da Cunha
The islands were first sighted in 1506 by Portuguese explorer Tristao da Cunha; rough seas prevented a landing. He named the main island after himself, Ilha de Tristao da Cunha, which was anglicised from its earliest mention on British Admiralty charts to Tristan da Cunha Island. Some sources state that the Portuguese made the first landing in 1520, when the Las Rafael captained by Ruy Vaz Pereira called at Tristan for water. The first undisputed landing was made in 1643 by the crew of the Heemstede, captained by Claes Gerritsz Bierenbroodspot.

in what year were the islands first sighted?
Output: 1506

Input: Electric motor
Stepper motors were and still are often used in computer printers, optical scanners, and digital photocopiers to move the optical scanning element, the print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers. Likewise, many computer plotters (which since the early 1990s have been replaced with large-format inkjet and laser printers) used rotary stepper motors for pen and platen movement; the typical alternatives here were either linear stepper motors or servomotors with closed-loop analog control systems.

In printers and copiers, what do stepper motors move?
Output: print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers

Input: Muammar Gaddafi
In June 1973, Gaddafi created a political ideology as a basis for the Popular Revolution. Third International Theory considered the U.S. and the Soviet Union as imperialist, thus rejected Western capitalism as well as Eastern bloc communism's atheism. In this respect it was similar to the Three Worlds Theory developed by China's political leader Mao Zedong. As part of this theory, Gaddafi praised nationalism as a progressive force and advocated the creation of a pan-Arab state which would lead the Islamic and Third Worlds against imperialism.

In what month and year did Gaddafi begin Third International Theory?
Output: June 1973

Input: LaserDisc
LaserDisc did not have high market penetration in North America due to the high cost of the players and discs, which were far more expensive than VHS players and tapes, and due to marketplace confusion with the technologically inferior CED, which also went by the name Videodisc. While the format was not widely adopted by North American consumers, it was well received among videophiles due to the superior audio and video quality compared to VHS and Betamax tapes, finding a place in nearly one million American homes by the end of 1990. The format was more popular in Japan than in North America because prices were kept low to ensure adoption, resulting in minimal price differences between VHS tapes and the higher quality LaserDiscs, helping ensure that it quickly became the dominant consumer video format in Japan. Anime collectors in every country the LD format was released, which includes both North America and Japan, also quickly became familiar with this format, and sought the higher video and sound quality of LaserDisc and the availability of numerous titles not available on VHS. LaserDiscs were also popular alternatives to videocassettes among movie enthusiasts in the more affluent regions of South East Asia, such as Singapore, due to their high integration with the Japanese export market and the disc-based media's superior longevity compared to videocassette, especially in the humid conditions endemic to that area of the world.

By 1990, how many American homes were estimated to use LD?
Output:
nearly one million
