Question: Did Osornio Martinez stay in Mexico after he married Maria Elvira Camarena Aldana? Passage 1:Prior to taking up speedway, Charles worked as a baker and grocer, and performed in music halls with a piano accordion. In 1929 Charles rode for Burnley, in 1930 for Manchester White City and then for Leeds Lions and Belle Vue in 1931 but was badly injured and lost his form, and so retired from the sport. In 1933, the Belle Vue Aces tempted him out of retirement, and looked to have regained his former form when he won the Wembley championship that year, also breaking the track record. In 1934 Charles' father died, so he returned to the family business. In 1935 Wembley Lions paid £1,000 to sign Charles, where he became the club's top scorer and was selected to ride for England against Australia. He went on to win the Star Riders' Championship despite only initially taking part in the competition as a replacement for Ginger Lees. In 1936 he topped the club's scoring again, was top scorer for the England Test team, and qualified for World Championship final, tying for fourth place with Cordy Milne, and broke the track record during the meeting. He qualified again for the 1937 final. At the end of the 1938 season he decided to retire to concentrate on his long-term hobby of gliding.
 Passage 2:He attended the Colegio San Luis Gonzaga and afterwards the Colegio Civil of Querétaro from 1883 to 1887. In 1892 he began his studies at the Escuela Nacional de Medicina (currently Faculty of Medicine of the UNAM) in Mexico City and graduated in 1893. As an officer candidate he completed the Escuela Práctica Médico-Militar (predecessor of the Escuela Médico Militar) at the military teaching hospital and made his specialty training in ophthalmology in the United States and in Canada from 1893 to 1895. In 1896 he married María Elvira Camarena Aldana and worked in Aguascalientes. He also was a liberal thinking politician, active in the city of Aguascalientes from 1903 to 1911 and as Deputy Governor of Aguascalientes from 1910 to 1911. From 1914 he served as a military surgeon on the side of revolutionary forces during the revolution, was promoted to the rank of Brigadier General (MC) in 1916. From June 1, 1916 to December 11, 1917 as well as from December 4, 1920 to December 16, 1934 he served as head of the medical branch in the Secretaría de Guerra y Marina. He was one of the founders of the Escuela Constitucionalista Médico Militar where he was director and taught as Professor of pathology, medical therapy and ophthalmology. From 1933 to 1934 he was director of the journal "Gaceta Médico Militar", the organ of the Mexican military branch. He died in Mexico City.
 Passage 3:The Uí Briúin Seóla was one of the major branches of the powerful Uí Briúin dynasty, which had become the dominant force in Connacht by the 8th century. The genealogies list two sons of Murchadh mac Maenach: Urchadh and Urumhain. Urchadh mac Murchadh, King of Maigh Seóla (also listed as king of Iarthair Connacht, died 945, in the 14th century Book of Ballymote) was father of Bé Binn inion Urchadh, Princess of the Uí Briúin Seóla and Queen of Thomond (fl. early 10th century). Bé Binn married Cennétig mac Lorcáin of Thomond to produce a son who would become the High King of Ireland (Irish: Ard-Rí na hÉireann): Brian Bóruma mac Cennétig, known in English as Brian Boru (c. 941–23 April 1014). Brian broke the near monopoly of the Uí Néill over the High Kingship of Ireland and fought to unite Ireland as a people under one, native king. His father, Cennétig mac Lorcáin of Thomond, was one of the principal leaders of the resistance to the Danish Viking incursions. Cennétig had several wives and children but positively assigned Bé Binn as the mother of Brian Bóruma.

Question: What are the 1968 Birthday Honours? Passage 1:In 1983 elections, N. T. Rama Rao came to power defeating the Indian National Congress. He praised the Naxalites for their patriotism before the elections. After coming to power, he demonstrated no significant change in government policy towards the revolutionary movement. Particularly after he was elected for a second time in 1985, his government put all its efforts to suppress the Naxalite movement in the state. Varavara Rao too was subjected to severe repression during this time. Six cases were foisted against him in 1985 alone. In July that year, along with functionaries of other people's organisations, he undertook an all India tour to make the people aware of the repression that was going on in Andhra Pradesh. After visiting Maharashtra, Madhya Pradesh, Bihar, West Bengal, New Delhi and Tamil Nadu, Varavara Rao returned to Andhra Pradesh in September to attend court cases. Dr. Ramanatham, a pediatrician and civil liberties activist was a close friend of Varavara Rao. While killing Dr. Ramanatham, and on several other occasions, police openly declared that killing Varavara Rao was their aim. With his life at risk, Varavara Rao could not discharge his duties as Secretary of Virasam and spokesperson of revolutionary literary movement. He was not able to move freely in Andhra Pradesh. Warangal has become a forbidden place for him. Armed and unarmed ruffians and police in civil clothes attacked his house on several occasions. Persecution against his friends in the movement was also mounted. Taking into consideration all these developments, Varavara Rao chose to cancel his bail in Secunderabad Conspiracy Case. On his request, his bail was cancelled and he was sent to jail on 26 December 1985.
 Passage 2:1973–74 was a big season for Newcastle United. The new attacking team put together by Harvey was being tipped to take one of the major honours come the season's end. By November Newcastle were second in the league, but they fell away to finish 15th, and in the League Cup they were knocked out in the third round. It was down to the FA Cup. Hendon were first up in the third round and a shock 2–2 draw at home meant that Newcastle had to go through a replay at Vicarage Road to see off the non-league side 3–0. Scunthorpe United were next up in the fourth round, and another shock 1–1 draw at St James' meant another replay against lower league opposition. Macdonald scored twice in the replay to crush Scunthorpe's hopes in a 3–0 win. The fifth round saw a difficult away draw to West Bromwich Albion, on a quagmire of a pitch and in front of the TV cameras. Newcastle were majestic, winning 3–0 with Macdonald scoring again. Newcastle faced Burnley at Hillsborough in the semi final. Macdonald scored two and Newcastle won 2–0; Harvey would sign Burnley defender Geoff Nulty for the next season after impressing in this game. Newcastle United were through to their first FA Cup final since 1955, where they would play Bill Shankly's Liverpool. Newcastle had a poor build up to final with preparations not going to plan: the tracksuit tops the players were meant to be wearing did not turn up, and they had to wear an unkind-looking purple outfit as they walked out at Wembley Stadium. Macdonald was the key man for Newcastle, having scored in every round for a total of eight goals in the competition. Liverpool played well and coasted to a 3–0 win with Kevin Keegan scoring twice. It was the end of an era for Harvey; the next season he signed Micky Burns and paid Sheffield Wednesday a club record £200,000 for Tommy Craig, but Newcastle could only finish a low 15th, despite getting some revenge on Liverpool, beating them 4–1 at St James' Park.
 Passage 3:Thomson was born in Glasgow; soon after he was born his family realised that Glasgow was full of John Thomsons and started calling him Ian. He was educated at the High School of Glasgow and the University of Glasgow. In 1939 he joined the Black Watch but was able to finish his studies at Glagow University, graduating with a degree in economics in 1940. He had already applied to join the Colonial Service, did so in 1941 and was sent to Fiji, then a British colony, as aide-de-camp to the Governor, Sir Harry Luke. He was commissioned in the Fiji Military Forces and saw action in the Solomon Islands campaign. He was appointed a military "in recognition of gallant and distinguished services in the South West Pacific" in 1945. After the war he served the Administration of Fiji, becoming a District Officer and eventually District Commissioner 1963–66. In 1967 he reluctantly left Fiji to become Governor of the British Virgin Islands (BVI). He was appointed in the 1968 Birthday Honours. In 1971 he returned to Fiji after being invited by the Prime Minister of the newly independent Dominion of Fiji, Ratu Sir Kamisese Mara, to chair the board of the Fiji Sugar Corporation. He was also chairman of Fiji's airline, Air Pacific. He was knighted KBE in the 1985 New Year Honours on the advice of the Fijian government.

Question: Which organization that Robertson as a fellow of was founded first? Passage 1:In September she was part of the covering force for the Salerno landings, but by the end of the year had been transferred to the Bay of Biscay to carry out anti-blockade-runner patrols, as part of Operation Stonewall. However, she soon returned to the Mediterranean, this time for Operation Shingle, the Anzio landings, in January 1944. In June 1944 she covered the landings in Normandy as part of Force D off Sword Beach, then carried out offensive patrols of the Brittany coast in August to mop up the remnants of the German shipping in the area. Operating with destroyers, she sank Sperrbrecher 157 on 14/15 August and during the battle of Battle of Audierne Bay sank five Vorpostenboote on 22/23 August. After this she returned to the Home Fleet, covering the carrier raids along the Norwegian coast and making anti-shipping strikes. On the night of 27/28 January 1945, in company with the cruiser , she fought the Action of 28 January 1945 with German destroyers in which was badly damaged. Following this action she was refitted at Cammell-Laird's between February 1945 and March 1946.
 Passage 2:Robertson was born in Scotland, and attended King’s College in Auckland, New Zealand. where his father, the Scotsman, Charles Alexander Robertson had been Headmaster. After studying accountancy he went into business with Nello Porter and W. H Hemingway forming an accounting firm, publishing house and correspondence school specialising in accountancy and business courses. They later split the business, and following an expansion to Australia he set up permanently in Melbourne in 1913. Robertson built the Melbourne headquarters at Bank House in Bank Place, Collins Street and opened offices throughout Australia and later operations in North America and the United Kingdom. In Britain he was made Vice President of the Royal Institute of Commerce from 1929 to 1930, a Fellow of the Society of Incorporated Accountants and Auditors and a Fellow of the Royal Society of the Arts. Following his return to Australia, Robertson was embroiled in a landmark High Court tax case, which contested his income in Britain. Ironically, it was his close friend Justice Owen Dixon who fined Robertson, and arranged for him to help amend the loophole in the Commonwealth tax laws. Afterwards it is rumored Robertson was satirically made to play left-handed (his non-preferred) against Dixon in a round of golf, which being ambidextrous he still won. A keen speculator and prudent investor, Robertson had far reaching pecuniary interests and directorial roles in mining, wheat and wool, as well as educational links through his Hemingway Robertson Institute with the University of Melbourne. He was made president of the Stock Exchange of Melbourne from 1934 to 1936, managing the formation of the Australian Associated Stock Exchanges (AASE) which opened in 1937. In his later years and up until his death, Robertson was a Victorian representative, and first chairman of the Melbourne branch, of the Liberal Party of Australia, and a confidant of Robert Menzies. Robertson was an important figure in the 1949 Australian federal election, and defeat of Ben Chifley, where Menzies and the newly formed Liberal Party won power in a massive landslide, scoring a 48-seat swing—still the largest defeat of a sitting government at the federal level in Australia.
 Passage 3:Sachs joined the faculty at Case Western Reserve University in 1957 and was made a full professor in 1966. He left Case Western Reserve to become the section chief of neurochemistry at The Roche Institute of Molecular Biology. Through his research, Sachs discovered the relationship between neurophysin, an intracellular chaperone protein and vasopressin, the neurohormone that is critical for maintaining water balance in the body. He hypothesized that neurophysin and vasopressin are both part of a larger, inactive precursor protein, a prohormone, which is then enzymatically cleaved and processed within the secretory granule to produce and secrete both peptide products. Sachs' hypothesis preceded the discovery of proinsulin by 3 years, and his research laid the foundation for understanding the biosynthesis of all brain peptides and many proteins, which are major constituents involved in brain and neuroendocrine functions. Sachs showed that vasopressin was first synthesized as a prohormone in specialized nerve cells (called neurosecretory cells) in the hypothalamus and was then transported to the nerve terminals in the posterior pituitary where the vasopressin peptide was completely processed during axonal transport in secretory granules and ultimately secreted into the blood. He also showed that brain tissue could be kept intact and functional for two months in tissue culture, and contributed to the understanding of the interactions between the neuroendocrine neurons and neuroglial cells in the hypothalamal-neurohypophysial system (HNS).
