You will be given a definition of a task first, then some input of the task.
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: Which of the counties that feeds the Lac qui Parle River has a larger land area? Passage 1:During the 2006/07 season, Liang reached at least the second round of qualifying in every ranking event. At the Northern Ireland Trophy, he beat Robert Stephen 5–0 before falling to David Gilbert 0–5 in qualifying. However, at the Grand Prix, Liang came top of his qualifying group, above more experienced players such as Gerard Greene and Barry Pinches. He finished fourth in his group at the round-robin stage, and although he did not progress to the next round, he did beat former world champion and world number one Stephen Hendry 3–0. At the UK Championship, he lost in the second round of qualifying to Jamie Burnett 7–9. In the following ranking event, the Malta Cup, he lost to Joe Jogia 3–5, again in the second round of qualifying. He qualified for the Welsh Open, his third ranking tournament, by beating Dene O'Kane, Joe Jogia and Mark Davis. He met Nigel Bond again in the last 48, this time losing only 3–5.
 Passage 2:The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.
 Passage 3:Jenkins was born in Merthyr Tydfil, Glamorgan on 30 January 1828. His father, William David Jenkins, could allegedly trace his ancestry back to Iestyn ap Gwrgant, the last Prince of Morgannwg. After attending Taliesin Williams's school in Merthyr Tydfil and Cowbridge Grammar School, Jenkins studied at Oxford University, matriculating at Jesus College in 1846 with the benefit of the Sir Leoline Jenkins scholarship. He studied Literae Humaniores, obtaining a third-class BA degree in 1850. He subsequently obtained further degrees: M.A. in 1852, BD in 1859 and DD in 1871. He became a good classical and oriental scholar whilst at Oxford, developing a fluency in modern languages in later life. Whilst an undergraduate, he tried and failed on several occasions for the Pusey and Ellerton Hebrew Scholarship; after his final failure, Dr Pusey presented him with some books to acknowledge his abilities in Hebrew.
