[Q]: Question: Who produced the movie starring Christoper Reeve which used the idea of a prison for villians? Passage:Another common use of the theme is as a prison for villains or demons. The idea is used in the first two Superman movies starring Christopher Reeve where Kryptonian villains were sentenced to the Phantom Zone from where they eventually escaped. An almost exactly parallel use of the idea is presented in the campy cult film The Adventures of Buckaroo Banzai Across the 8th Dimension, where the "8th dimension" is essentially a "phantom zone" used to imprison the villainous Red Lectroids. Uses in horror films include the 1986 film From Beyond (based on the H. P. Lovecraft story of the same name) where a scientific experiment induces the experimenters to perceive aliens from a parallel universe, with bad results. The 1987 John Carpenter film Prince of Darkness is based on the premise that the essence of a being described as Satan, trapped in a glass canister and found in an abandoned church in Los Angeles, is actually an alien being that is the 'son' of something even more evil and powerful, trapped in another universe. The protagonists accidentally free the creature, who then attempts to release his "father" by reaching in through a mirror.

[Q]: 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.

[Q]: Question: How often is the World Water Forum held? Passage:The 2nd World Water Forum held in The Hague in March 2000 raised some controversies that exposed the multilateral nature and imbalance the demand and supply management of freshwater. While donor organizations, private and government institutions backed by the World Bank, believe that freshwater should be governed as an economic good by appropriate pricing, NGOs however, held that freshwater resources should be seen as a social good. The concept of network governance where all stakeholders form partnerships and voluntarily share ideas towards forging a common vision can be used to resolve this clash of opinion in freshwater management. Also, the implementation of any common vision presents a new role for NGOs because of their unique capabilities in local community coordination, thus making them a valuable partner in network governance.
