Problem: Given the following context: The Abbasid Caliphate, founded by Abu al-'Abbas 'Abdu'llah ibn Muhammad as-Saffah, the great-great-grandson of Muhammad's uncle Abbas, in 749, had ruled northeastern Africa, Arabia, and the Near East, even though their rule had by 1258 shrunk to only southern and central Iraq. The Abbasids' seat of power for almost 500 years was Baghdad, a city considered to be the jewel of Islam and one of the largest and most powerful cities in the world. But under attack from the Mongols, the city fell on February 15, 1258, a loss often considered in the Muslim world as the single most catastrophic event in the history of Islam, the end of the Islamic Golden Age. The Christian Georgians had been the first to breach the walls, and as described by historian Steven Runciman, "were particularly fierce in their destruction". When Hulagu conquered the city, the Mongols demolished buildings, burned entire neighborhoods, and massacred nearly all the men, women, and children. But at the intervention of Doquz Khatun, the Christian inhabitants were spared. For Asiatic Christians, the fall of Baghdad was cause for celebration. Hulagu and his Christian queen came to be considered as God's agents against the enemies of Christianity, and were compared to the influential 4th-century Christian Emperor Constantine the Great and his revered empress mother, Saint Helen, an icon of the Christian church. The Armenian historian Kyrakos of Gandzak praised the Mongol royal couple in texts for the Armenian Church, and Bar Hebraeus, a bishop of the Syriac Orthodox Church, also referred to them as a Constantine and Helena, writing of Hulagu that nothing could compare to the "king of kings" in "wisdom, high-mindedness, and splendid deeds". answer the following question: What were the full names of the two people Hulagu and his Christian queen were compared to?

A: Christian Emperor Constantine the Great

Problem: Given the following context: Against this background, a "great assembly" was organised by the Manchester Patriotic Union formed by radicals from the Manchester Observer. The newspaper's founder Joseph Johnson was the union's secretary. He wrote to Henry Hunt asking him to chair a meeting in Manchester on 2 August 1819. Johnson wrote: Nothing but ruin and starvation stare one in the face [in the streets of Manchester and the surrounding towns], the state of this district is truly dreadful, and I believe nothing but the greatest exertions can prevent an insurrection. Oh, that you in London were prepared for it. Unknown to Johnson and Hunt, the letter was intercepted by government spies and copied before being sent to its destination. The contents were interpreted to mean that an insurrection was being planned, and the government responded by ordering the 15th Hussars to Manchester. The mass public meeting planned for 2 August was delayed until 9 August. The Manchester Observer reported it was called "to take into consideration the most speedy and effectual mode of obtaining Radical reform in the Common House of Parliament" and "to consider the propriety of the 'Unrepresented Inhabitants of Manchester' electing a person to represent them in Parliament". The magistrates, led by William Hulton, had been advised by the acting Home Secretary, Henry Hobhouse, that "the election of a member of parliament without the King's writ" was a serious misdemeanour, encouraging them to declare the assembly illegal as soon as it was announced on 31 July. The radicals sought a second opinion on the meeting's legality which was that "The intention of choosing Representatives, contrary to the existing law, tends greatly to render the proposed Meeting seditious; under those circumstances it would be deemed justifiable in the Magistrates to prevent such Meeting."On 3 August, Hobhouse conveyed the view of the Attorney-General that the magistrates were incorrect to declare 9 August meeting illegal as it was called to consider the election of a representative and... answer the following question: What is the first name of the person who advised against any attempt to forcibly prevent the 9 August meeting if it went ahead, or do anything beyond collecting evidence for subsequent prosecution unless the meeting got out of hand?

A: Henry

Problem: Given the following context: Descriptions of Imogen as a small child indicate that she had blue eyes, fair hair, an oval face reminiscent of her father's, and a rather prominent nose inherited from her mother. In 1912, at the age of five, she joined the kindergarten class at the Froebel Institute, and remained at the school for five years. Summers were often spent at the Holsts' rented country cottage at Thaxted in Essex, where Gustav Holst began an annual Whitsun Festival in 1916.In 1917 Imogen began boarding at Eothen, a small, private school for girls in Caterham, where Jane Joseph, Gustav's star pupil from SPGS, taught music. A letter home, dated 17 July 1917, tells of "compertishions [sic], and ripping prizes, and strawberries and cream for tea". At the school, Imogen studied piano with Eleanor Shuttleworth, violin with Andre Mangeot (described as "topping") and theory with Jane Joseph ("ripping"). Under Joseph's tuition Imogen produced her first compositionstwo instrumental pieces and four Christmas carol tuneswhich she numbered as Ops. 1, 2, and 3. In the summer term of 1920, she composed and choreographed a "Dance of the Nymphs and Shepherds", which was performed at the school under her direction on 9 July.Imogen left Eothen in December 1920 hoping to study under Ruby Ginner at the Ginner-Mawer School of Dance and Drama, but was rejected on health grounds, although there appeared to be no significant medical issue. She then studied at home under a governess, while waiting to start at St Paul's Girls School in the autumn. At Whitsun 1921 she took part as a dancer in her father's production of Purcell's semi-opera from 1690, Masque of Dioclesian, held in the St Paul's School grounds and repeated a week later in Hyde Park.In September 1921 Imogen began at St Paul's Girls School, and became a boarder from Spring 1922. In July 1922 she performed a Bach Prelude and Fugue on the piano, for which Joseph praised her warmly, writing: "I think everyone enjoyed the Bach from beginning to end, they all made nice contented noises at the... answer the following question: What is the name of the person who played Chopin's etude in E major and gave the first performance of Gustav Holst's Toccata at an end-of-term school concert late in July 1925?

A:
Imogen
