Teacher:In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Teacher: Now, understand the problem? Solve this instance: Question: How long did the financial period last that delayed work on the park? Passage 1:Gary di Silvestri is a graduate of Monsignor Farrell High School in Staten Island, New York, where he was a member of the football, wrestling and track & field teams. He graduated salutatorian and was awarded the top student athlete on Staten island. He has an undergraduate degree from Georgetown University where he graduated Magna Cum Laude and was inducted into the Phi Beta Kappa National Honor Society. Gary also has a Masters of Business Administration from Columbia University, where he graduated with honors and was inducted into the Beta Gamma Sigma national honors society. He has had a long career in financial services, having worked for Credit Suisse First Boston in London, England; and Morgan Stanley in both London and New York City. In 1997, di Silvestri founded Deutsche Suisse Asset Management, and he said his business success had allowed him to pursue philanthropy full time.
Passage 2:On November 29, 2017, at 3 p.m., after playing "End Game" by Taylor Swift, WQMP flipped to alternative rock as Alt 101.9joining several other former "AMP Radio"-branded stations in switching to the format and brand after the completion of the Entercom merger. The change brought the format back to a full-market signal in Orlando for the first time since 2008, when sister station WOCL flipped to classic hits. The most recent analog broadcast station to air the format full-time, Cox Media's W297BB/WCFB-HD2, was aired on a translator and an HD sub-channel, and aired from June 2014 to January 2016. Elsewhere in the Orlando market, iHeartMedia's talk-formatted WTKS-FM features alternative on nights and weekends, and is also aired on two HD subchannels in the Orlando market, WOCL HD2 and WJRR HD3, the latter of which also uses the brand Alt as standardized by iHeartMedia; this name conflict resulted in WQMP quietly changing its on-air brand to FM 101.9. WQMP's flip to alternative made former sister station WXXL the de facto CHR station in Orlando, until WPYO flipped to CHR from an urban-leaning rhythmic contemporary format in April 2018.
Passage 3:A $2.5 million bond issue passed in 1922 for a stadium conceived by Burnham. Designed by architects Holabird & Roche and named Soldier Field for the veterans of World War I, cost overruns required another bond issue in 1926. By 1924, the breakwater wall stretched from 14th to 55th Streets. In 1926, Soldier Field and a portion of Lake Shore Drive were opened. Landfilling extended from 23rd Street to 56th Street; however, Promontory Point was not complete, prompting complaints regarding garbage, blowing sand and odors. Throughout the 1920s and 1930s, landfill efforts continued to fill in Burnham Park and the adjacent Northerly Island. The South Development was named for Daniel Burnham on January 14, 1927, and support increased for a world's fair in the park. Construction was completed on Lake Shore Drive, with northbound lanes named for Leif Erikson, and southbound lanes for Christopher Columbus. In 1929, construction of the park at Promontory Point began. The Great Depression delayed work and prevented construction of nearshore islands. Burnham Park was chosen for the site of the Century of Progress world's fair and a yacht basin was built south of 51st Street.
