Input: Question: What is the population of the place where the extension would connect to West Kirby? Passage 1:In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
 Passage 2:Meléndez began his wrestling career in 1951 at age 18. During a lengthy tenure in his native Puerto Rico, he went under various monikers and learned the ropes with the likes of Pedro Morales and Carlos Colón Sr.. Meléndez made his United States debut at Sunnyside Garden in Long Island, New York in 1963. Primarily using the name Gypsy Joe by this point, he mainly worked for Nick Gulas and later Jerry Jarrett in the Southeastern region, particularly Mid-Southern Wrestling. During his Gulas run, he was often teamed with heels like Tojo Yamamoto, with whom he formed the No Pain Train, and The Cuban Assassin. He also joined forces with Frank Martinez to be collectively known as the Blue Infernos. The masked duo would attain tag team championships on numerous occasions. By the 1970s, Gypsy Joe was a local star of Chattanooga, Tennessee, regularly performing at Soldiers and Sailors Memorial Auditorium on Saturdays and appearing on local WDEF-TV. His career wasn't limited to the South, however, winning championships around the country as well as in Canada’s Stampede Wrestling.
 Passage 3:Coming off their win over the Steelers the Jets played an interconference duel with the Bears. In the first quarter the Jets trailed early as kicker Robbie Gould got a 37-yard field goal, followed by Matt Forte getting a 22-yard TD run. The Jets pulled ahead with RB Shonn Greene getting a 3-yard TD run, followed by CB Dwight Lowery returning an interception 20 yards for a touchdown, followed by RB LaDainian Tomlinson getting a 3-yard TD run letting the Jets lead 21–10. The lead was narrowed as QB Jay Cutler scrambled 2 yards for a touchdown, but was soon extended as kicker Nick Folk made a 26-yard field goal. They trailed again with Cutler completing a 40 and a 25-yard TD pass to wide receivers Devin Hester and Johnny Knox respectively, but soon were able to tie the game with QB Mark Sanchez throwing a 23-yard TD pass to WR Santonio Holmes. The Bears escaped the tie with Cutler finding Knox again on a 26-yard TD pass. The Jets tried to come back, but only came away with a 34-yard field goal from Folk. When the Jets got the ball back, Sanchez threw a pass intended for Holmes, only to be intercepted by safety Chris Harris with 0:58 to go.
