 Passage 2:After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.

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 sent back to the Lake Erie Monsters on October 25 but was recalled on November 18 after Semyon Varlamov suffered a groin injury. Pickard earned his first win on November 22 after coming in to relieve an ineffective Reto Berra, Pickard stopped all 17 shots he faced in an eventual 4-3 Overtime win. After more poor play from Berra, Pickard became the starting goaltender and continued in impressive form until Semyon Varlamov permanently returned to the team, after which Pickard became the team's primary backup goaltender. Pickard was returned to Lake Erie on December 28, in order to resume a starting goaltender role. In the 2015–16 season Pickard began the year with Colorado's new AHL affiliate the San Antonio Rampage, he was recalled early on in the season when Semyon Varlamov suffered a groin injury. He would return to the club in late December when Reto Berra injured his ankle, Pickard recorded his first NHL shutout on January 16, 2016 against the New Jersey Devils.
 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.
