Problem:Context_1 : The National Zoo and Aquarium is a privately owned 25 acre zoo and aquarium in the Australian capital city of Canberra. It is located in Yarralumla at the western end of Lake Burley Griffin also next to Scrivener Dam. It is currently undergoing major expansion works, with a further 30 acre of Open Range exhibits being constructed, which is due to open late 2016 Context_2 : Open Range is a 2003 American western film directed and co-produced by Kevin Costner, starring Robert Duvall and Costner, with Annette Bening, Michael Gambon, and Michael Jeter appearing in supporting roles. The film was the final on-screen appearance of Jeter, who died before it was released, and the film was dedicated to Jeter's memory, and to that of Costner's parents, Bill and Sharon. Context_3 : Emile Meyer (August 18, 1910 – March 19, 1987) was an American actor (born in New Orleans) usually known for tough, aggressive, authoritative characters in Hollywood films from the 1950s era, mostly in westerns or thrillers. Meyer was plucked from a crowd scene by Elia Kazan in his "Panic in the Streets" (1950) to play an uncredited small speaking role as a sea captain in that film. He provided such noteworthy performances as Rufus Ryker the cattle baron who makes a strong case for the open range in "Shane" (1953), as the belligerent Mr Halloran in "The Blackboard Jungle" (1955), cast against type by Stanley Kubrick as Father Dupree in "Paths of Glory" (1957) and the corrupt cop Harry Kello who intends to 'chastise' Tony Curtis in "Sweet Smell of Success" (1957). He appeared in an episode of the 1961 series "The Asphalt Jungle". Context_4 : The Sheepshooters' War was an armed conflict fought in central and eastern Oregon. Like other range wars in the Old West, the war pitted cattlemen against sheepherders. Because the cattlemen were unwilling to share the open range with the sheepherders, due to concerns about overgrazing, they formed paramilitary organizations with the goal of eliminating the flocks of sheep and anyone who attempted to stop them. Between 1895 and 1906, the Sheepshooters, as they were called, slaughtered at least 10,000 sheep. A few men were also killed during gunfights or related incidents. Context_5 : Miklos Wright is an American film editor. He graduated from the Rhode Island School of Design where he received a B.A. His career began as an assistant editor on the film "Lobsterman from Mars" (1987). His most notable works include "Open Range" and "Mr. Brooks", both of which starred Kevin Costner, along with doing multiple episodes of "Southland (TV Series)" and "Chicago PD (TV Series)". Context_6 : African Safari World was a proposed amusement park and zoo, to replace the Werribee Open Range Zoo, 32 km southwest of Melbourne, Australia. Warner Village Theme Parks, who already own and operate several properties on the Gold Coast in Queensland, was behind the proposal. The park was scheduled to open in 2010. On 1 June 2008 the Victorian government said it had rejected the proposal, because the cost to the taxpayer would have been too great. Context_7 : A tapadero, sometimes referred to as a "hooded stirrup," is leather cover over the front of a stirrup on a saddle that closes each stirrup from the front. A tapadero prevents the rider's boot from slipping through and also prevents brush encountered while working cattle on the open range from poking through the stirrup, injuring or impeding the horse or rider. Some designs can also provide protection in cold weather. They are also frequently used with young riders, as many parents and riding instructors feel they are a safety precaution. Most commonly seen today on a western saddle, particularly certain types of children's saddles and parade horse saddles, the "tapadero" is not common in modern times and is not allowed in most show competition other than Parade Horse competition and children's leadline. Context_8 : In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. Where there are "open range" laws, those wanting to keep animals off their property must erect a fence to keep animals out; this applies to public roads as well. Land in open range that is designated as part of a "herd district" reverses liabilities, requiring an animal's owner to fence it in or otherwise keep it on the person's own property. Most eastern states and jurisdictions in Canada require owners to fence in or herd their livestock. Context_9 : A range war is a type of armed conflict that occurs in agrarian or stock-rearing societies. The subject of these conflicts was control of "open range", or range land freely used for cattle grazing, which gave the conflict its name. Typically they were disputes over water rights or grazing rights. Context_10 : Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience. We are able to place in memory visual information which resembles objects, places, animals or people in a mental image. The experience of visual memory is also referred to as the mind's eye through which we can retrieve from our memory a mental image of original objects, places, animals or people. Visual memory is one of several cognitive systems, which are all interconnected parts that combine to form the human memory. Types of palinopsia, the persistence or recurrence of a visual image after the stimulus has been removed, is a dysfunction of visual memory. fact_1 :  His most notable works include "Open Range" and "Mr. Brooks", both of which starred Kevin Costner, along with doing multiple episodes of "Southland (TV Series)" and "Chicago PD (TV Series)". fact_2 :  The film was the final on-screen appearance of Jeter, who died before it was released, and the film was dedicated to Jeter's memory, and to that of Costner's parents, Bill and Sharon.
