Q: 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.
Question: What city is the Tour of Flanders? Passage 1:In 1998, one week after winning E3 Harelbeke and the Brabantse Pijl in the same weekend, he won the Tour of Flanders, thereby equaling the race's record of three wins. One week later, Museeuw made a horrific fall in Paris–Roubaix on the Trouée d'Arenberg cobbled sector, leaving his kneeknap shattered. On top came a dangerous gangrene infection which nearly forced doctors to amputate his left leg. He fought back and resumed cycling after a long healing process, finishing third in the Tour of Flanders of 1999 and ninth in Paris–Roubaix, exactly one year after his horror crash. In 2000 he won Paris–Roubaix a second time after a 44 km solo. Upon crossing the finish line in victory, he lifted his left leg, pointing to his knee as a reminder of the injury that had almost ended his career two years before. Later that year, he was again injured in a motor cycle accident, causing a severe head trauma and several days in a coma. His dogged determination and powerful riding style won him legions of fans all over the world and made him all the more popular in his native Flanders.
 Passage 2:A Colorado low is a low-pressure area that forms in southeastern Colorado or northeastern New Mexico, typically in the winter. After forming, the system moves across the Great Plains. Colorado lows can produce heavy wintry precipitation, and have a general east to northeast movement, impacting regions as far north as Winnipeg and as far east as the Atlantic coast. If upper level conditions are right, the jet stream can push the low farther south, bringing wintry precipitation as far as Texas. When pushed this far south, the system is often referred to as a "blue norther". On the more typical track, a Colorado low can be similar to an Alberta clipper. In the winter Colorado lows are responsible for a majority of the snow that the Midwest receives; however, summer systems can trigger long-lasting convective systems, including severe weather. Spring and early summer Colorado low cyclogenesis can result in significant tornado outbreaks over the Great Plains and Midwest.
 Passage 3:According to the United States Census Bureau, the city has a total area of , of which is land and is water, comprising 1.35% of the city. Berlin is situated at the confluence of the Androscoggin and Dead rivers. The Mahoosuc Range is to the southeast. Jericho Mountain State Park, created from a city park and from private land in 2005, is west of the city center and features a reservoir created in the 1970s and a network of ATV trails. The city's highest point is Mount Weeks, at above sea level. A prominent feature in the landscape of Berlin is Mount Forist, rising over the west side of the city. Approximately half of Berlin lies within the Connecticut River watershed, and half lies in the Androscoggin River watershed.
