Please answer this: What is the answer for the question: Who did not realize that Catherine was married? from the following article ?  Married couple Caleb, a fire captain, and Catherine Holt, a hospital administrator, are experiencing marital difficulties. At work, Caleb underscores the importance of never leaving one's partner behind, but at home, he and Catherine argue copiously. Catherine accuses Caleb of being selfish due to his desire to buy a boat taking preference over paying for her mother's medical bills, and frustrated over his habitual use of internet pornography. Caleb feels unappreciated and undervalued. Their constant arguing causes Catherine to demand a divorce, to which an enraged Caleb agrees. Caleb's coworker Michael and father John convince him to hold off on divorce proceedings. His father persuades him to try the Love Dare, a 40-day challenge for improving marriages by changing the way a spouse is treated. Caleb reluctantly agrees, though he decides not to tell Catherine. At the hospital where she works, Catherine has been openly flirting with Dr. Gavin Keller. Caleb begins The Love Dare halfheartedly viewing the tasks as more of a checklist, while nurses at Catherine's hospital warn her not to trust him, as they interpret his actions as a way to butter her up for a better divorce settlement. With encouragement from his father and Michael, Caleb continues, though Catherine eschews his affections and grows closer to Dr. Keller. Finding Catherine unmoved, Caleb is consoled by his father while Michael reveals that he has been divorced. Caleb sustains burns on the job, and while being treated at the hospital where his wife works, Dr. Keller inadvertently discovers that Catherine is married and he is treating her husband, but continues his affections. Caleb continues The Love Dare with renewed faith and Catherine gives him an envelope petitioning for divorce.

Problem: What is the answer for the question: What are the names of the sport that is played in a Tzykanisterion? from the following article ?  Byzantines were avid players of tavli (Byzantine Greek: τάβλη), a game known in English as backgammon, which is still popular in former Byzantine realms, and still known by the name tavli in Greece. Byzantine nobles were devoted to horsemanship, particularly tzykanion, now known as polo. The game came from Sassanid Persia in the early period and a Tzykanisterion (stadium for playing the game) was built by Theodosius II (r. 408–450) inside the Great Palace of Constantinople. Emperor Basil I (r. 867–886) excelled at it; Emperor Alexander (r. 912–913) died from exhaustion while playing, Emperor Alexios I Komnenos (r. 1081–1118) was injured while playing with Tatikios, and John I of Trebizond (r. 1235–1238) died from a fatal injury during a game. Aside from Constantinople and Trebizond, other Byzantine cities also featured tzykanisteria, most notably Sparta, Ephesus, and Athens, an indication of a thriving urban aristocracy. The game was introduced to the West by crusaders, who developed a taste for it particularly during the pro-Western reign of emperor Manuel I Komnenos.

A: tzykanion

Problem: Given the question: What is the answer for the question: What is the last name of the person who had undertaken an epic horse ride to Adelaide to establish an alibi? from the following article ?  The Avenue Range Station massacre was the murder of a group of Aboriginal Australians by white settlers during the Australian frontier wars. It occurred in about September 1848 at Avenue Range, a sheep station in the southeast of the Colony of South Australia. Information is scarce about the basic facts of the massacre, including the exact date and number of victims. A contemporary account of the massacre listed nine victims – three women, two teenage girls, three infants, and an "old man blind and infirm". Another account published by Christina Smith in 1880 gave the number of victims as eleven, and specified that they belonged to the Tanganekald people. Pastoralist James Brown and his overseer, a man named Eastwood, were suspected of committing the murders in retaliation for attacks on Brown's sheep. In January 1849, reports of the massacre reached Matthew Moorhouse, the Protector of Aborigines. He visited the district to investigate the claims, and based on his enquiries Brown was charged with the murders in March 1849. Proceedings against Brown began in June 1849 and continued in the Supreme Court of South Australia for several months, but were eventually abandoned. Some key witnesses, including Eastwood, either fled the colony or refused to cooperate with the investigation. There were also significant restrictions on the use of evidence given by Aboriginal witnesses, especially where a verdict could involve capital punishment. These legal hurdles and settler solidarity ensured the case did not go to trial, although the magistrate who committed him for trial told a friend that there was "little question of the butchery or the butcher". Although the details of the case were known for decades after the murders, distortions of the massacre eventually appeared in print and were embellished by local white and Aboriginal historians. Two key aspects of these later accounts were that Brown poisoned rather than shot the victims, and that he had undertaken an epic horse ride to Adelaide to establish an alibi....

Brown

Q: What is the answer for the question: What was the first name of Sir Terence Aubrey Murray's wife? from the following article ?  The area now called Yarralumla is part of two original land grants, which were granted to free settlers for the establishment of farms. In 1828 Henry Donnison, a Sydney merchant who had arrived with his wife and family on the brig Ellen on 29–30 July 1828, was granted an allotment on the western side of Stirling Ridge. A second grant was made to William Klensendorlffe (a German who had served in the British Navy and arrived free in the Colony in 1818), who had bought the land from John Stephen, on 7 March 1839. Donnison's land was named Yarralumla in a survey of the area conducted in 1834. Yarralumla was a name for the area used by the local people, apparently meaning "echo". An area to the west of what is now the suburb was the Yarrolumla parish.The prominent New South Wales parliamentarian Sir Terence Aubrey Murray (1810–1873) purchased Yarralumla in 1837. He lived there with his wife Mary Murray (née Gibbes, 1817–1858), the second daughter of the Collector of Customs for NSW, Colonel John George Nathaniel Gibbes (1787–1873), MLC. In 1859, Murray sold Yarralumla to his brother-in-law, Augustus Onslow Manby Gibbes (1828–1897). Later that same year, Augustus' parents came to live with him at Yarralumla homestead. Augustus Gibbes improved the estate and acquired additional land by purchase and lease. However, In 1881, he sold Yarralumla for 40,000 pounds to Frederick Campbell, a descendant of Robert Campbell, in order to travel overseas. Frederick Campbell erected a new, three-storey, brick house on the site of the former Yarralumla homestead at the beginning of the 1890s. Campbell's house would later form the basis of what is now the Governor-General of Australia's official Canberra residence, known colloquially as "Yarralumla" or "Government House". Campbell also built a large wooden woolshed nearby in 1904. It remains standing to this day.In 1908, the Limestone Plains area, including Yarralumla, was selected as the site for the capital city of the newly established Commonwealth of Australia. Soon afterwards...
