Problem: Around 746, Abu Muslim assumed leadership of the Hashimiyya in Khurasan. In 747, he successfully initiated an open revolt against Umayyad rule, which was carried out under the sign of the black flag. He soon established control of Khurasan, expelling its Umayyad governor, Nasr ibn Sayyar, and dispatched an army westwards. Kufa fell to the Hashimiyya in 749, the last Umayyad stronghold in Iraq, Wasit, was placed under siege, and in November of the same year Abu al-Abbas was recognized as the new caliph in the mosque at Kufa.[citation needed] At this point Marwan mobilized his troops from Harran and advanced toward Iraq. In January 750 the two forces met in the Battle of the Zab, and the Umayyads were defeated. Damascus fell to the Abbasids in April, and in August, Marwan was killed in Egypt.
Where did Marwan die?
The answer is the following: Egypt

Just as Lee explores Jem's development in coming to grips with a racist and unjust society, Scout realizes what being female means, and several female characters influence her development. Scout's primary identification with her father and older brother allows her to describe the variety and depth of female characters in the novel both as one of them and as an outsider. Scout's primary female models are Calpurnia and her neighbor Miss Maudie, both of whom are strong willed, independent, and protective. Mayella Ewell also has an influence; Scout watches her destroy an innocent man in order to hide her desire for him. The female characters who comment the most on Scout's lack of willingness to adhere to a more feminine role are also those who promote the most racist and classist points of view. For example, Mrs. Dubose chastises Scout for not wearing a dress and camisole, and indicates she is ruining the family name by not doing so, in addition to insulting Atticus' intentions to defend Tom Robinson. By balancing the masculine influences of Atticus and Jem with the feminine influences of Calpurnia and Miss Maudie, one scholar writes, "Lee gradually demonstrates that Scout is becoming a feminist in the South, for with the use of first-person narration, she indicates that Scout/ Jean Louise still maintains the ambivalence about being a Southern lady she possessed as a child."
Who are Scout's two primary female models?
Calpurnia and Miss Maudie

Input: The Blitz
British air doctrine, since the time of Chief of the Air Staff Hugh Trenchard in the early 1920s, had stressed offence was the best means of defence. British defensive strategy revolved around offensive action, what became known as the cult of the offensive. To prevent German formations from hitting targets in Britain, RAF's Bomber Command would destroy Luftwaffe aircraft on their own bases, aircraft in their factories and fuel reserves by attacking oil plants. This philosophy was impractical as Bomber Command lacked the technology and equipment and needed several years to develop it. This strategy retarded the development of fighter defences in the 1930s. Dowding agreed air defence would require some offensive action, and fighters could not defend Britain alone. Until September 1940, the RAF lacked specialist night-fighting aircraft and relied on anti-aircraft units which were poorly equipped and lacking in numbers.

Why was the tactic of bombing German aircraft bases, factories and fuel reserves impractical?
Output: lacked the technology and equipment

Input: Article: HDTV technology was introduced in the United States in the late 1980s and made official in 1993 by the Digital HDTV Grand Alliance, a group of television, electronic equipment, communications companies consisting of AT&T Bell Labs, General Instrument, Philips, Sarnoff, Thomson, Zenith and the Massachusetts Institute of Technology. Field testing of HDTV at 199 sites in the United States was completed August 14, 1994. The first public HDTV broadcast in the United States occurred on July 23, 1996 when the Raleigh, North Carolina television station WRAL-HD began broadcasting from the existing tower of WRAL-TV southeast of Raleigh, winning a race to be first with the HD Model Station in Washington, D.C., which began broadcasting July 31, 1996 with the callsign WHD-TV, based out of the facilities of NBC owned and operated station WRC-TV. The American Advanced Television Systems Committee (ATSC) HDTV system had its public launch on October 29, 1998, during the live coverage of astronaut John Glenn's return mission to space on board the Space Shuttle Discovery. The signal was transmitted coast-to-coast, and was seen by the public in science centers, and other public theaters specially equipped to receive and display the broadcast.

Now answer this question: When was HDTV introduced in the US?

Output: late 1980s

Article: Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research.

Question: Which groups of researchers provided unorthodox structure for a research group?
Ans: Pickford's and Hutchinson's

Input: Madonna (entertainer)
The MDNA Tour, which further promoted the album, began in May 2012 in Tel Aviv, Israel. The tour has received positive critical reception, but featured controversial subjects such as violence, firearms, human rights, nudity and politics. Lawsuits threatened against Madonna have also been engaged from the tour. It was a box office success with a gross of $305.2 million from 88 sold-out shows, and became the highest-grossing tour of 2012 and the tenth highest-grossing tour of all time. At the 2013 Billboard Music Awards, Madonna won three trophies for Top Touring Artist, Top Dance Artist and Top Dance Album. Madonna was named the top-earning celebrity of the year by Forbes, earning an estimated $125 million, due to the success of the tour.

How many shows were sold out?
