Example Input: Question: Which of East 17's singles stayed in the top 10 for the least number of weeks? Passage:Twenty-five artists scored multiple entries in the top 10 in 1994. American singer Mariah Carey, East 17 and British boy-band Take That shared the record for the most top ten singles in 1994 with four hit singles each. Carey's cover of the Badfinger song "Without You" was her biggest hit of the year; it reached number-one in February and spent four weeks in that position, and eight weeks in the top 10 in total. Her other top ten singles were "All I Want for Christmas Is You" (number 2) in December; "Endless Love" (3) with Luther Vandross in September; and "Anytime You Need a Friend" (8) in June. Three of Take That's four top ten singles reached number-one in the UK: "Babe" in December 1993, "Everything Changes" in April and "Sure" in October. "Love Ain't Here Anymore" was their other top 10 entry, which reached number 3 in July. East 17 also had a number-one single in 1994, "Stay Another Day", which stayed there for 5 of its 8 weeks in the top ten. Their other top ten singles were "Around the World" and "It's Alright (both number 3) and "Steam" (number 7). Bon Jovi, Oasis and Eternal had three singles in the top ten in 1994.

Example Input: Question: Which of the three reservoirs produced by the damming of the Hackensack River was built first? Passage:The damming of the Hackensack River and a tributary, the Pascack Brook, produced three reservoirs in the county, Woodcliff Lake Reservoir (which impounds one billion gallons of water), Lake Tappan (3.5 billion gallons), and Oradell Reservoir, which allows United Water to provide drinking water to 750,000 residents of northern New Jersey, mostly in Bergen and Hudson counties. The Hackensack River drains the eastern portion of the county through the New Jersey Meadowlands, a wetlands area in the southern portion of the county. The central portion is drained by the Saddle River and the western portion is drained by the Ramapo River. Both of these are tributaries of the Passaic River, which forms a section of the southwestern border of the county.

Example Input: Question: What year did buddhism come to Thailand? Passage:There is no official state religion in the Thai constitution, which guarantees religious freedom for all Thai citizens, though the king is required by law to be a Theravada Buddhist. The main religion practised in Thailand is Buddhism, but there is a strong undercurrent of Hinduism with a class of brahmins having sacerdotal functions. The large Thai Chinese population also practises Chinese folk religions, including Taoism. The Chinese religious movement Yiguandao (Thai: Anuttharatham) spread to Thailand in the 1970s and it has grown so much in recent decades to come into conflict with Buddhism; in 2009, it was reported that each year 200,000 Thais convert to the religion. Many other people, especially among the Isan ethnic group, practise Tai folk religions. A significant Muslim population, mostly constituted by Thai Malays, is present especially in the southern regions.
