Question: How old was Alexander's wife when they got married? Passage 1:The Irish government under outgoing Taoiseach Enda Kenny expressed concerns that a parliamentary deal between a British government and the DUP could put the Northern Ireland peace process at risk, a view also expressed by Sinn Fein politicians Gerry Adams and Gerry Kelly, Labour MP Yvette Cooper and former Downing Street Director of Communications Alastair Campbell. This opinion was, however, rejected by the Conservative leadership and former Secretary of State for Northern Ireland, Theresa Villiers, as well as by former Labour minister Caroline Flint who suggested that Gordon Brown may have sought an agreement with the DUP in 2010. The Conservative peer and former UUP First Minister of Northern Ireland, David Trimble, described claims that an agreement would put the peace process at risk as "scaremongering". On 13 June former Conservative Prime Minister John Major publicly urged May to govern without DUP support and not pursue a deal, on the grounds that an agreement could "damage" the "fragile" Northern Ireland peace process, suggesting the government must remain 'impartial'. Major himself had an agreement with the Unionist MPs of the UUP when in power and during peace negotiations in Northern Ireland, though not with the more hardline and socially-conservative DUP. On 15 June Sinn Fein's Gerry Adams met with Theresa May, telling her that he thought she was in breach of the Good Friday Agreement. This has been disputed by one of the UUP's negotiators for the Belfast Agreement.
Passage 2:He testified as an expert witness about Russian interference in the 2016 United States elections, in a March 30, 2017 hearing before the United States Senate Select Committee on Intelligence. His testimony before the Senate Intelligence Committee was well received, and made multiple headlines. Slate referred to him in a headline as: "Clint Watts, Testifier Extraordinaire", and "The star of March's Senate Intelligence Committee hearing". CNN profiled him after the testimony in a piece "Russia investigation: Who is Clint Watts", where it was noted he gained knowledge in the field of Russian cyber hacking methods, after himself being a target in 2015 following his "Trolling for Trump" article; the FBI notified the Foreign Policy Research Institute of the attack. Salon compared his testimony "follow the trail of dead Russians" to John Dean's statement about "a cancer on the presidency". This phrase in testimony by Watts was highlighted by the media, including CBS News, The American Interest, and The Oregonian. U.S. Senator Ron Wyden found the comment important to his investigation. Mark Shields of PBS NewsHour found his testimony "compelling", and CNN called it "blistering". Jennifer Rubin wrote for The Washington Post that his testimony "laid out the most comprehensive look at the array of tools Russia used to influence our election". After his testimony, he appeared on NBC's Meet the Press and explained ways the U.S. can better respond to cyberwarfare.
Passage 3:Ancient historians, as well as modern ones, have also written on Alexander's marriage to Roxana the beautiful [Persian]n woman. Robin Lane Fox writes, "Roxana was said by contemporaries to be the most beautiful lady in all Asia. She deserved her name of Roshanak, meaning 'little star', (probably rokhshana or roshana which means light and illuminating) in Persian. Marriage to a local noble's family made sound political sense, but contemporaries implied that Alexander, aged 28, also lost his heart. A wedding-feast for the two of them was arranged high on one of the Persian rocks. Alexander and his bride shared a loaf of bread, a custom still observed in Turkestan. Characteristically, Alexander sliced it with his sword. Ulrich Wilcken writes, "The fairest prize that fell to him was Roxana, the daughter of Oxyartes, in the first bloom of youth, and in the judgment of Alexander's companions, next to Stateira the wife of Darius, the most beautiful woman that they had seen in Asia. Alexander fell passionately in love with her and determined to raise her to the position of his consort."

Question: What year was Tevaram published? Passage 1:For the lead roles, Christopher Meloni was cast as Detective Elliot Stabler and Mariska Hargitay was cast as Detective Olivia Benson after they auditioned together. Hargitay, who had to move from Los Angeles to New York when she got the role, said she was able to do this on short notice because she was already planning on moving to New York to pursue a Broadway career. The squad commander role was filled by Dann Florek, who had portrayed Captain Don Cragen for the first three seasons on the original Law & Order and later reprised his role in . He joined the cast on the condition that he not be asked to audition. Richard Belzer was cast as Detective John Munch, continuing his role from the series . In Belzer's words, he was cast because "Dick Wolf and Tom Fontana got drunk at a party". Halfway through the season, Richard Belzer reprised his role of Munch in , which briefly shows his character out on a case in his SVU context in New York. At Belzer's insistence, his character was partnered with Brian Cassidy, who was portrayed by Dean Winters. However, Winters' contractual obligation to the HBO series Oz forced him to leave halfway through the season. Michelle Hurd, who portrayed Detective Monique Jeffries, filled Winters' void for the remainder of the season, and was at that point added to the main credits.
Passage 2:The old name forms of Waldbockelheim (now a neighbouring municipality), Schlobockelheim and Talbockelheim (now an outlying centre), can be traced back to an 824 document that names . The name Schlobockelheim first cropped up only in the 17th century. In the 19th century, the name Thalbockelheim first came to light. On 1 November 1910, municipal council agreed to introduce Schlobockelheim as the municipality's name. The name Talbockelheim seems to have had its spelling changed in line with the spelling reforms over the years; it is now written without the first H, but the name Schlobockelheim itself has not been changed in the wake of the German orthography reform of 1996; the has not been changed to SS. The three prefixes that serve to distinguish the three centres whose names are otherwise the same are all standard German words with well understood meanings: Wald ("forest"); Schlo (or Schloss in up-to-date spelling; "castle/palace"); Tal ("dale/valley"). The village chronicle has this to say about the village's name:Until the beginning of the last century (meant here is the 19th century) the village was named after the castle Schlobockelheim, which still existed in the 17th century. The castle was destroyed by the French in 1688. The village of Thalbockelheim consists of the two constituent centres of Thalbockelheim and Schlobockelheim: Schlobockelheim with the ruin of Castle Bockelheim lies on the mountainside and the constituent centre of Thalbockelheim lies 0.5km away down in the dale. Both constituent centres have roughly the same population figure. The village's name was changed in quite a peculiar way. In the early part of the last century, in response to an inquiry by the authorities as to what the village was called, because it consisted of two constituent centres, the name Thalbockelheim was given by the then Schoffe (roughly "lay jurist"). The Schoffe lived in the constituent centre of Thalbockelheim and a certain selfishness on his part made him want to call the village Thalbockelheim, without regard to the historical importance of the constituent centre of Schlobockelheim. None of the locally customary rural cadastral names had to do with the name Thalbockelheim, but rather they were named after Schlobockelheim, like Schlobockelheimer Muhlberg, Schlobockelheimer Felsenberg, Schlobockelheimer Kupfergrube and so on. Wines had earned quite an important reputation as Schlobockelheimer in the wine trade, whereas Thalbockelheim never cropped up in the wine trade. Municipal council asked on these grounds to have the historical name Schlobockelheim reinstated, as it was already well known throughout Germany for Emperor Heinrich IV's imprisonment at Castle Bockelheim (1105).Also given as grounds for the reversion to the older name was the name's recognizability in winegrowing and the wine trade. A decree made on 22 April 1911 approved the municipality's application. Since this time, the two constituent centres of Thalbockelheim and Schlobockelheim have been united under the collective name "Schlobockelheim". Among the places in the middle Naheraum (regions flanking the Nahe), Schlobockelheim belongs among those places that were already often being mentioned in the Middle Ages. Castle Bockelheim, built on what was to become Schlobockelheim's municipal area, was among the oldest in the region. Generally regarded as the village's first documentary mention is a document from 16 February 824. Late in 1105, Emperor Heinrich V, the last of the Salian dynasty, had his father, Emperor Heinrich IV taken prisoner in Ingelheim and then brought to Castle Bockelheim to be held prisoner there. In 1688, the Nine Years' War (known in Germany as the Pfalzischer Erbfolgekrieg, or War of the Palatine Succession) broke out. That year, the castle was destroyed on French orders.
Passage 3:The 7th century Nayanar saints Sambandar and Appar wrote of the temple in their poetic work, Tevaram. The original masonry and towers date back to the 9th century CE, as seen from an inscription in the structure made by Chola kings. The Chola kings ruled over the region for more than four centuries, from 850 CE to 1280 CE, and were temple patrons. The temple complex dates from the time of the 10th century AD Medieval Chola king Uttama Chola whose inscriptions are found in its walls. An inscription dated to the fifteenth year of Raja Raja Chola makes a reference to "Panchavanmahadevi chaturvedimanagalam", which is another name for Nallur. There are also inscription by Later Chola kings and by Hoysala monarchs. The inscriptions from the Chola kings record various gifts like land, sheep, cow and oil to the temple commemorating various victories of the dynasty. There are lot of inscriptions from the Sangama Dynasty (13361485 CE), Saluva Dynasty, and Tuluva Dynasty (14911570 CE) of the Vijayanagara Empire, reflecting gifts to the temple from their rulers. The majority of the gift related inscriptions are for land endownments, followed by goods, cash endowments, cows and oil for lighting lamps. The temple has been maintained by the Thiruvaduthurai Adheenam from the early part of the 13th century.

Question: How many years did the ruler of the Sasanian Empire when it had confrontations with the Chionites rule the empire? Passage 1:Early confrontations between the Sasanian Empire of Shapur II with the nomadic hordes from Central Asia called the "Chionites" were described by Ammianus Marcellinus: he reports that in 356 CE, Shapur II was taking his winter quarters on his eastern borders, "repelling the hostilities of the bordering tribes" of the Chionites and the Euseni ("Euseni" is usually amended to "Cuseni", meaning the Kushans), finally making a treaty of alliance with the Chionites and the Gelani, "the most warlike and indefatigable of all tribes", in 358 CE. After concluding this alliance, the Chionites (probably of the Kidarites tribe) under their King Grumbates accompanied Shapur II in the war against the Romans, especially at the Siege of Amida in 359 CE. Victories of the Xionites during their campaigns in the Eastern Caspian lands were also witnesses and described by Ammianus Marcellinus.
Passage 2:Thanjavur was successfully conquered in 1674 by Ekoji I (167584), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (178793) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855 by the Doctrine of Lapse when Shivaji II (183255), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters.
