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.
Q: Question: What is the definition of the Werther effect? Passage 1:In July 1994, two students of Taipei First Girls' High School committed suicide by charcoal-burning in a hotel in Su'ao, Yilan with a note that didn't state the reason clearly, even though that it was suspected in some mass media that they were a lesbian couple. In November 1998, a middle-aged woman in Hong Kong died by suicide using this method inside her small, sealed bedroom. She had a chemical engineering background. Hong Kong was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local mass media, many others killed themselves in this way (an example of the Werther effect). Within two months, charcoal-burning had become the third major suicide killer in Hong Kong. Charcoal-burning suicide accounted for 1.7% of Hong Kong suicides in 1998 and 10.1% in 1999. By 2001, it had surpassed hanging as the second most-common method of suicide in Hong Kong (second only to jumping), accounting for about 25% of all suicide deaths. The method has since spread to mainland China, Taiwan and Japan.
 Passage 2:Landesman was born and raised in St. Louis, Missouri, studied at Colby College and then the University of Wisconsin, Madison (BA English Literature 1969), and the Yale School of Drama (MFA Dramatic Literature and Criticism 1972, DFA 1976). At the Yale School of Drama he became a protégé and friend of Robert Brustein. At the completion of his course work he stayed at Yale for four years as an Assistant Professor. While at Yale, Landesman got to know novelist Jerzy Kosinski and he worked with Kosinski on two of his novels, Being There and The Devil Tree. Landesman was involved as an editor, helping Kosinski, not a native speaker of English, with his English syntax and writing. While at Yale Landesman was also involved in managing a private mutual fund and a racehorse he had bought. In 1977 he left to focus more time on his private investment fund, which he ran for many years. He also got involved in Broadway theater and he was heavily involved in the genesis and development of "Big River" (1985 Tony, Best Musical), a musical based on Huckleberry Finn. Landesman's involvement included persuading Roger Miller to write the music for the show. The show ultimately won seven Tonys and ran for over 1,000 performances on Broadway over two and a half years. This success attracted the attention of James H. Binger who shared two passions with Landesman: Broadway theater and horseracing. Binger owned the Jujamcyn Theatre group of five theatres, four of which were then dark. Binger and Landesman made a deal for Landesman to become President of Jujamcyn in 1987 with the inclusion of an option for Landesman to purchase Jujamcyn upon Binger's death. After taking the helm at Jujamcyn he shifted its business model away from the historical focus of renting of theatre facilities to shows and into a more active posture as a combination of a theater owner and a developer of new plays. Other theater owners have followed this pattern. After joining Jujamcyn Landesman has produced Broadway shows, the most notable of which include: "" (1993 and 1994 Tony, Best Play), and "The Producers" (2001 Tony, Best Musical). Landesman purchased Jujamcyn in 2005 and later sold a 50% interest to Jordan Roth.
 Passage 3:The first inter-state numbering for the Roosevelt Highway was in New England, where the New England road marking system was established in 1922. Route 18 followed the auto trail from Portland northwest to Montpelier, where it continued to Burlington via Route 14. Many of the states along the route also assigned numbers to the highway; for instance, New York labeled their portion Route 3 in 1924. The Joint Board on Interstate Highways distributed its preliminary plan in 1925, in which a long section of the highway was labeled US 2, from St. Ignace, Michigan west to Bonners Ferry, Idaho. East of St. Ignace, instead of crossing to the Lower Peninsula like the Roosevelt Highway, the proposed Route 2 traveled north to the international border at Sault Ste. Marie. It reappeared at Rouses Point, New York, following Route 30 and then rejoining the auto trail between Burlington and Montpelier. US 2 and the Roosevelt Highway both connected Montpelier to St. Johnsbury, but the latter took a direct path along Route 18, while the former was assigned to Route 25 to Wells River, where it overlapped proposed US 5 north to St. Johnsbury. There, where the Roosevelt Highway turned southeast to Portland, Route 2 continued east along Route 15 to Bangor and Route 1 to Calais, then heading north on Route 24 to end in Houlton.
