 Passage 2:A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.

Example Input: Question: How many copies of the duet produced by Gary Klein were sold? Passage 1:Having left Casablanca Records, with whom she had had some of the biggest selling and most popular hits of the disco era in the 1970s, Summer had signed to Geffen Records in 1980 and had continued working with Giorgio Moroder and Pete Bellotte, with whom she had written the vast majority of her hits. However, label owner David Geffen had been disappointed with the chart performance of the 1980 The Wanderer, Summer's debut album for Geffen and rather than release the followup; I'm a Rainbow which Summer had recorded with Moroder/Bellotte in 1981. Geffen had Summer record a new album with Quincy Jones from whom a production credit – given Jones' track record particularly his work with Michael Jackson – Geffen felt would guarantee a commercial smash. The resultant Donna Summer album was the first time the singer had worked with a producer other than Moroder and Bellotte since 1974 save for the one-off track "Down Deep Inside (Theme from "The Deep")" which was produced by John Barry for the film The Deep, and the "No More Tears (Enough is Enough)" duet with Barbra Streisand which was co-produced by Gary Klein of The Entertainment Company.

Pickard was returned to Lake Erie on December 28, in order to resume a starting goaltender role.

 Passage 3:Although there is no evidence of lower or middle Paleolithic settlements in Tripura, Upper Paleolithic tools made of fossil wood have been found in the Haora and Khowai valleys. The Indian epic, the Mahabharata; ancient religious texts, the Puranas; and the Edicts of Ashoka – stone pillar inscriptions of the emperor Ashoka dating from the third century BCE – all mention Tripura. An ancient name of Tripura is Kirat Desh (English: "The land of Kirat"), probably referring to the Kirata Kingdoms or the more generic term Kirata. However, it is unclear whether the extent of modern Tripura is coterminous with Kirat Desh. The region was under the rule of the Twipra Kingdom for centuries, although when this dates from is not documented. The Rajmala, a chronicle of Tripuri kings which was first written in the 15th century, provides a list of 179 kings, from antiquity up to Krishna Kishore Manikya (1830–1850), but the reliability of the Rajmala has been doubted.

 Passage 2:Klammer first showed signs of promise in the second half of the 1973 World Cup season, finishing second in the St. Anton downhill behind Bernhard Russi of Switzerland, the reigning Olympic and World Cup downhill champion. Klammer, age 19, followed this up with a third at St. Moritz and a third in the giant slalom at Mont Sainte-Anne (the only time he finished on the podium in a World Cup Giant Slalom in his career). The following season he finished second in the downhill standings behind Roland Collombin of Switzerland, his nemesis that season. After beating Collombin and Russi at Schladming in December 1973 under terrible conditions, Collombin bested him at Garmisch, Avoriaz, and Wengen. In December 1974, Collombin fell at Val-d'Isère, as he had the previous year. This time Collombin broke his back in a training run, unfortunately ending his promising career. Klammer won that race and every other downhill that 1975 season, except Megève, where one of his skis came off; without this incident, he would have won the overall World Cup title in March 1975, due to a good slalom result two days before at Chamonix, which would have granted him at least a third place (15 points) for the AK-combined of slalom Chamonix / downhill Megève. In the Olympic test event at Patscherkofel at Innsbruck in January 1975, Klammer had defeated defending Olympic champion Bernhard Russi of Switzerland, the runner-up, by nearly a half-second.
