Instructions: 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.
Input: Question: Who proposed the legislative routes? Passage 1:Close to the West Pennine Moors, Bolton is northwest of Manchester. It is surrounded by several smaller towns and villages that together form the Metropolitan Borough of Bolton, of which Bolton is the administrative centre. The town of Bolton has a population of 139,403, whilst the wider metropolitan borough has a population of 262,400. Historically part of Lancashire, Bolton originated as a small settlement in the moorland known as Bolton le Moors. In the English Civil War, the town was a Parliamentarian outpost in a staunchly Royalist region, and as a result was stormed by 3,000 Royalist troops led by Prince Rupert of the Rhine in 1644. In what became known as the Bolton Massacre, 1,600 residents were killed and 700 were taken prisoner.
 Passage 2:Eros Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, flowing southeast from the Planet Heights into George VI Sound immediately north of Fossil Bluff. It was probably first seen on November 23, 1935, by Lincoln Ellsworth, who flew directly over the glacier and obtained photos of features north and south of it. The mouth of the glacier was observed and positioned by the British Graham Land Expedition in 1936 and the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. It was named by the UK Antarctic Place-Names Committee after the minor planet Eros in association with nearby Pluto Glacier and Uranus Glacier.
 Passage 3:In 1908, the New York State Legislature created a statewide system of unsigned legislative routes. The portion of what is now NY 34 from Van Etten to Ithaca was included in Route 9, which originally began in Horseheads and went generally northeast across central New York to Bouckville. North of Ithaca, two sections of modern NY 34—from Cayuga Heights Road north to current NY 34B in Lansing and from the north end of NY 34B in Fleming to Auburn—became part of Route 11. On March 1, 1921, Route 9 was realigned south of Van Etten to follow modern NY 34 south to Chemung Street in Waverly. When the first set of posted routes in New York were assigned in 1924, none of modern NY 34 received a signed designation except for the current overlap between NY 34 and NY 13 south of Ithaca, which became NY 13 at this time.
