Problem: Text: Open Water is a 2003 American survival horror thriller film. The story concerns an American couple who go scuba diving while on vacation in the Caribbean, only to find themselves stranded miles from shore in shark-infested waters when the crew of their boat accidentally leaves them behind. The film is loosely based on the true story of Tom and Eileen Lonergan, who in 1998 went out with a scuba diving group, Outer Edge Dive Company, on the Great Barrier Reef, and were accidentally left behind because the dive-boat crew failed to take an accurate headcount. The film was financed by the husband and wife team of writer/director Chris Kentis and producer Laura Lau, both avid scuba divers. It cost $120,000 to make and was bought by Lions Gate Entertainment for $2.5 million after its screening at the Sundance Film Festival. Lions Gate spent a further $8 million on distribution and marketing. The film ultimately grossed $55 million worldwide (including $30 million from the North American box office alone).

Problem: Text: Zone defenses are common in international, college, and youth competition. In the National Basketball Association, zone defenses were prohibited until the 2001--2002 season, and most teams do not use them as a primary defensive strategy. The NBA has a defensive three-second violation rule, which makes it more difficult for teams to play zone, since such defenses usually position a player in the middle of the key to stop penetration. The Dallas Mavericks under coach Rick Carlisle are an example of an NBA team that have regularly used zone defenses.

Problem: Text: Although phylogenetically they are closer to felines and viverrids, and belong to the feliform category, hyenas are behaviourally and morphologically similar to canines in several elements of convergent evolution; both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. Both eat food quickly and may store it, and their calloused feet with large, blunt, nonretractable claws are adapted for running and making sharp turns. However, the hyenas' grooming, scent marking, defecating habits, mating and parental behaviour are consistent with the behaviour of other feliforms.
