Question: I have a test where I am given the following article, what is an answer for the question: What is the last name of the person who composed seven operas in three years at Brunswick? ? Handel joined the Hamburg opera house when it was experiencing a period of considerable artistic success. This blossoming followed the arrival of Reinhard Keiser, who had become musical director at the Gansemarkt in about 1697, and in 1703 succeeded Johann Kusser as the theatre's manager. Born in 1674, Keiser had studied under Johann Schelle and probably Johann Kuhnau at the Thomasschule zu Leipzig. In 1694 he was employed as a court composer at Brunswick, where in three years he composed seven operas, at least one of which (Mahumeth) was performed in Hamburg. According to Handel's biographer Donald Burrows, Keiser was a good judge of popular taste, with a flair for writing Italian-style arias. Between 1697 and 1703, prior to Handel's arrival, about a dozen more Keiser operas had been staged at the Gansemarkt. Despite his on-stage successes, Keiser was an unreliable general manager, with expensive private tastes and little financial acumen, often at odds with his creditors.It is possible that Keiser, who had connections in the Halle area, had heard of Handel and was directly instrumental in securing the latter's post in the Gansemarkt orchestra; certainly he was a considerable influence on the younger man in the three years that Handel spent in Hamburg. Another important Gansemarkt colleague was the house composer and singer Johann Mattheson, who noted Handel's rapid progress in the orchestra from back-desk violinist to harpsichord soloist, a role in which, said Mattheson, "he showed himself a mana thing which no one had before suspected, save I alone". Mattheson was less complimentary on Handel's early efforts at composition: "He composed very long, long arias, and really interminable cantatas", before, it seems, "the lofty schooling of opera ... trimmed him into other fashions".
Answer: Keiser

[Q]: I have a test where I am given the following article, what is an answer for the question: What was the name of the person who promised to explain the decision at a media conference and vowed that he and his colleagues would return to purely military roles in the near future? ? The four officers were taken aback by Taylor's searing words and felt they had been humiliated. A decade after the incident, Ky described Taylor as "the sort of man who addressed people rather than talked to them", referencing the confrontation. Karnow said "For the sake of their own pride, they [the Vietnamese officers] resented being treated in ways that reminded them of their almost total dependence on an alien power. How could they preserve a sense of sovereignty when Taylor, striving to push them into 'getting things done', behaved like a viceroy?" However, Thi also took a perverse pleasure in riling Taylor. He was seen by a CIA officer soon after, grinning. When asked why he was happy, Thi said "Because this is one of the happiest days of my life ... Today I told the American ambassador that he could not dictate to us." Nevertheless, Taylor's conduct had rankled the officers, stirring their latent sense of nationalism and anti-Americanism; Khanh would exploit this to strengthen his fragile position in the junta.Khanh's quartet of delegates responded to Taylor in a circumlocutory way. They remained calm and did not resort to direct confrontation. Ky said the change was necessary, as "the political situation is worse than it ever was under Diem". Ky explained that the situation mandated the dissolution of the council, saying "We know you want stability, but you cannot have stability until you have Unity." He claimed some HNC members were disseminating coup rumors and creating doubt among the population, and that "both military and civilian leaders regard the presence of these people in the High National Council as divisive of the Armed Forces due to their influence". Ky further accused some of the HNC members of being communist sympathizers and cowards who wanted to stop the military from strengthening. He promised to explain the decision at a media conference and vowed that he and his colleagues would return to purely military roles in the near future. Thieu added "I do not see how our action has hurt...

input: Please answer the following: I have a test where I am given the following article, what is an answer for the question: What are the names of the four craters that were formed at the same time? ? In recent years, several other craters of around the same age as Chicxulub have been discovered, all between latitudes 20N and 70N. Examples include the disputed Silverpit crater in the North Sea, and the Boltysh crater in Ukraine. Both are much smaller than Chicxulub, but are likely to have been caused by objects many tens of meters across striking the Earth. This has led to the hypothesis that the Chicxulub impact may have been only one of several impacts that happened nearly at the same time. Another possible crater thought to have been formed at the same time is the larger Shiva crater, though the structure's status as an impact crater is contested.The collision of Comet ShoemakerLevy 9 with Jupiter in 1994 demonstrated that gravitational interactions can fragment a comet, giving rise to many impacts over a period of a few days if the comet should collide with a planet. Comets undergo gravitational interactions with the gas giants, and similar disruptions and collisions are very likely to have occurred in the past. This scenario may have occurred on Earth at the end of the Cretaceous, though Shiva and the Chicxulub craters might have been formed 300,000 years apart.In late 2006, Ken MacLeod, a geology professor from the University of Missouri, completed an analysis of sediment below the ocean's surface, bolstering the single-impact theory. MacLeod conducted his analysis approximately 4,500 kilometres (2,800 mi) from the Chicxulub crater to control for possible changes in soil composition at the impact site, while still close enough to be affected by the impact. The analysis revealed there was only one layer of impact debris in the sediment, which indicated there was only one impact. Multiple-impact proponents such as Gerta Keller regard the results as "rather hyper-inflated" and do not agree with the conclusion of MacLeod's analysis, arguing that there might only be gaps of hours to days between impacts in a multiple-impact scenario (cf. Shoemaker-Levy 9) which would not leave a detectable gap in deposits.
