[Q]: Question: How long had the United Nations been in existence when Gross was appointed? Passage 1:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
 Passage 2:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
 Passage 3:The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.

[Q]: Question: How many denizens lived in Rome the year Fabio Mignanelli moved to the city? Passage 1:In 1533, he moved to Rome, becoming a consistorial advocate. He was married to Antonina Capodiferro, the sister of Cardinal Girolamo Recanati Capodiferro and had a son. After Antonia died, Mignanelli entered the church. In 1537, he was sent as ambassador to the Republic of Venice to encourage Venice to break its alliance with the Ottoman Empire and to go to war against the Ottomans. In October 1537, Pope Paul III sent him as ambassador to Charles V, Holy Roman Emperor to present him with the brief postponing the Council of Trent for a second time. In spring 1538, he traveled to Nice with the pope to negotiate the end of the Italian War of 1536–1538; shortly thereafter, they traveled to Geneva to meet the emperor. On September 3, 1538, he was appointed nuncio to Ferdinand, King of the Romans, holding this position until 1539. In 1540, he became an auditor of the Roman Rota. He was also a protonotary apostolic and the pope's domestic prelate.
 Passage 2:Mikva is the daughter of Judge Abner Mikva and Zorita ("Zoe") (nee Wise) Mikva. Mikva and her two sisters were raised in Evanston, Illinois, and attended public schools. She earned her B.A. in theater at Beloit College in 1974, working after graduation as a paralegal at the law firm Jenner & Block. She then attended Northwestern University Pritzker School of Law, graduating cum laude and Order of the Coif in 1980. Following graduation, she served as law clerk to Judge Prentice Marshall of the United States District Court for the Northern District of Illinois, and then to Justice William J. Brennan, Jr., of the United States Supreme Court. After her clerkships, Mikva practiced law in Chicago as a partner at Abrahamson Vorachek & Mikva and Seliger & Mikva, specializing in civil rights and employment law, and in criminal defense with Patrick A. Tuite & Associates. 
 Passage 3:The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames.

[Q]: Question: How old was the series that Grampa and Jasper imitate? Passage 1:Born in Bucharest, her parents were the writer Vasile Demetrius and his wife Antigona (née Rabinovici). Her beloved father had attended Saint Sava High School, where one of his classmates was Ion G. Duca, who would become Lucia's godfather. Her mother was a baptized Jew; she had numerous siblings and the family was very poor. She attended the elite Maria Brâncoveanu central school from 1921 to 1928; its director, to whom she grew close, was the widow of Barbu Ștefănescu Delavrancea. This was followed by the University of Bucharest, where she earned degrees in literature (1931) and philosophy (1932). A student at the Dramatic Arts Conservatory from 1928 to 1931, she had Ion Manolescu as a professor. She formed part of the Sburătorul literary circle. Asking Ion Marin Sadoveanu for help in finding a job, he sent her to act at Cernăuți, and would also appear at Brașov and Bucharest, invariably in minor roles.
 Passage 2:He had more likeable roles in two British children's TV series: The Ghosts of Motley Hall, which ran from 1976 to 1978 on ITV (produced by Granada Television), and as "Slugger" in Follyfoot, which ran from 1971 to 1973, also on ITV (produced by Yorkshire Television). He was in several other films and Everyday Maths (1978), a British TV schools programme starring Jack Wild as English's grandson. In 1978 he was the subject in This Is Your Life, while in May 1983 he was a guest on Desert Island Discs with Roy Plomley. Also in 1983 he played Frosch in Die Fliedermaus with English National Opera at the London Coliseum. In 1985 he appeared in an episode of the American TV series Magnum, P.I..
 Passage 3:Additionally, Homer sings Billy Joel's 1983 song "Uptown Girl". After drinking the tainted juice, Grampa and Jasper sit on a bench, laughing like the title characters from the series Beavis and Butt-head, while Flanders hallucinates skeletons and dancing bears (images associated with the Grateful Dead), marching hammers (from Pink Floyd's 1982 film Pink Floyd—The Wall) and The Rolling Stones' lips and tongue logo. Mr. Burns' film is credited as "An Alan Smithee Film", a reference to the Alan Smithee pseudonym credit used by directors who wanted to be disassociated from a film on which they had lost creative control, to the detriment of the final product. When Barney drinks alcohol to prevent the bad effects from the tainted juice, a pink elephant comes to his rescue, referencing the scene in Dumbo where Dumbo and Timothy drink alcohol and see pink elephants. Seth and Munchie's dog is named Ginsberg, thought to be a reference to beat poet Allen Ginsberg. Homer putting the flowers in the policemen's rifles is a reference to the iconic October 22, 1967 Life magazine picture, "Flower Power" by Bernie Boston.
