Example Input: A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably wild mouse roller coasters, run with single cars.
Example Output: when was the first ever roller coaster built

Example Input: Jordan played three seasons for coach Dean Smith at the University of North Carolina. As a freshman, he was a member of the Tar Heels' national championship team in 1982. Jordan joined the Bulls in 1984 as the third overall draft pick. He quickly emerged as a league star, entertaining crowds with his prolific scoring. His leaping ability, demonstrated by performing slam dunks from the free throw line in slam dunk contests, earned him the nicknames Air Jordan and His Airness. He also gained a reputation for being one of the best defensive players in basketball. In 1991, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 and 1993, securing a 'three-peat'. Although Jordan abruptly retired from basketball before the beginning of the 1993 -- 94 NBA season to pursue a new venture in minor league baseball, he returned to the Bulls in March 1995 and led them to three additional championships in 1996, 1997, and 1998, as well as a then-record 72 regular-season wins in the 1995 -- 96 NBA season. Jordan retired for a second time in January 1999, but returned for two more NBA seasons from 2001 to 2003 as a member of the Wizards.
