Example Input: Question: Which of the construction materials that St Nicholas was constructed with has a higher value on the Mohs scale? Passage:St Nicholas is constructed in flint, with some conglomerate and brick, and has limestone dressings. The roofs are tiled. Its plan consists of a nave, a chancel with a north vestry (previously a porch), and a west tower. The tower is wholly octagonal. In each face of the upper stage of the tower is a lancet, and there is another lancet on the west side at a lower level. The parapet is battlemented. The tower has a west doorway in Norman style, which has possibly been re-set from elsewhere in the church. It has scalloped capitals, and zig-zag decoration on the arch. Inside the upper part of the tower is a 17th-century dovecote lined with brick nesting boxes. On the south side, between the tower and the nave, is a brick stair turret. The nave windows have two lights with Decorated tracery. Between the windows on the south side is another Norman doorway, again with zig-zag decoration. The north and south walls of the chancel have two-light windows with Y-tracery, and three-light windows with Perpendicular tracery. The east window has five lights. The east gable is decorated with grotesque carvings, and above the east window is head-corbel and a blocked niche. The vestry has two-light north and south windows. In the north wall of the nave is an Early English doorway, with dog-tooth ornament. Around the church are stepped buttresses.

Example Input: Question: In what year was Albert Park Circuit opened up for its first race? Passage:Beechey began racing at the age of 22 in a Ford Customline V8. He came to prominence only a year later when he won the Olympic Touring Car Race at Albert Park, a support event at the Australian Grand Prix meeting which was held in conjunction with the 1956 Melbourne Olympic Games. As the expense of running this and two subsequent Customline V8s proved too prohibitive he reverted to a Holden 48-215 in 1959. After becoming part of David McKay's Scuderia Veloce team he again returned to V8s, developing a Chevrolet Impala with which he won the New South Wales Touring Car Championship at Catalina Park. He progressed to a Ford Galaxie owned by Len Lukey and was then instrumental in forming the Neptune Racing Team in 1964. He raced a Holden EH S4 as part of that team alongside Jim McKeown's Lotus Cortina and Peter Manton's Morris Cooper S. He subsequently developed and raced a series of V8 powered Touring Cars with which he contested the Australian Touring Car Championship and other events. The first Ford Mustang to race in Australia was followed by a Chevrolet Chevy II Nova, a Chevrolet Camaro, a Holden Monaro GTS 327 and a Holden Monaro GTS 350.

Example Input: Question: What was the first film directed by the director of Not My Life? Passage:Angie was later interviewed in the documentary film Not My Life, in which Angie explains how she and Melissa were expected to engage in sexual intercourse with truck drivers at a truck stop and steal their money. Angie said that, while looking through one of these drivers' wallets, she found pictures of the man's grandchildren and realized that he was old enough to be her and Melissa's grandfather. She recounts this story disgustedly and almost crying, and says, "I wanted to die." Beaver also appears in the film, saying, "It's not just truck drivers. We're seeing them purchased and abused by both white collar and blue collar individuals." Robert Bilheimer, the film's director, said that Angie did not fit the stereotype for a girl at risk of being sexually trafficked: she was from the heartland, attended a private school and, when her parents divorced, she began acting out as a way of seeking attention. A man abducted her when she was 12 years old, violated the Mann Act by transporting her to another state, and began trafficking her sexually. While being trafficked, Angie was expected to engage in 40 sex acts every night, charging $20 for oral sex, $40 for vaginal sex, and $80 for both. Her trafficker threatened to kill her if she refused to perform these acts. Bilheimer said that the truck drivers Angie was expected to service either did not know or did not want to know what would happen to her if she did not give all of the money she earned to her pimp.
