Problem: Energy:

In cosmology and astronomy the phenomena of stars, nova, supernova, quasars and gamma-ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen). The nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang. At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight.

What theory states that space expanded and the universe cooled very slowly for hydrogen to completely fuse into heavier elements?

A: unanswerable

Problem: Elizabeth's many historic visits and meetings include a state visit to the Republic of Ireland and reciprocal visits to and from the Pope. She has seen major constitutional changes, such as devolution in the United Kingdom, Canadian patriation, and the decolonisation of Africa. She has also reigned through various wars and conflicts involving many of her realms. She is the world's oldest reigning monarch as well as Britain's longest-lived. In 2015, she surpassed the reign of her great-great-grandmother, Queen Victoria, to become the longest-reigning British head of state and the longest-reigning queen regnant in world history.
What was the last year that Elizabeth did a state visit in the Republic of Ireland?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On 4 April 1786, Burke presented the Commons with the Article of Charge of High Crimes and Misdemeanors against Hastings. The impeachment in Westminster Hall, which did not begin until 14 February 1788, would be the "first major public discursive event of its kind in England", bringing the morality and duty of imperialism to the forefront of public perception. Burke already was known for his eloquent rhetorical skills and his involvement in the trial only enhanced its popularity and significance. Burke's indictment, fuelled by emotional indignation, branded Hastings a 'captain-general of iniquity'; who never dined without 'creating a famine'; whose heart was 'gangrened to the core', and who resembled both a 'spider of Hell' and a 'ravenous vulture devouring the carcasses of the dead'. The House of Commons eventually impeached Hastings, but subsequently, the House of Lords acquitted him of all charges.
Which house acquitted Hastings?
A: House of Lords

Context and question: In 1870, republican sentiment in Britain, fed by the Queen's seclusion, was boosted after the establishment of the Third French Republic. A republican rally in Trafalgar Square demanded Victoria's removal, and Radical MPs spoke against her. In August and September 1871, she was seriously ill with an abscess in her arm, which Joseph Lister successfully lanced and treated with his new antiseptic carbolic acid spray. In late November 1871, at the height of the republican movement, the Prince of Wales contracted typhoid fever, the disease that was believed to have killed his father, and Victoria was fearful her son would die. As the tenth anniversary of her husband's death approached, her son's condition grew no better, and Victoria's distress continued. To general rejoicing, he pulled through. Mother and son attended a public parade through London and a grand service of thanksgiving in St Paul's Cathedral on 27 February 1872, and republican feeling subsided.
Where was the republica rally held that called for Vuictorias removal?
Answer: Trafalgar Square

Question: Suger, friend and confidant of the French Kings, Louis VI and Louis VII, decided in about 1137, to rebuild the great Church of Saint-Denis, attached to an abbey which was also a royal residence. He began with the West Front, reconstructing the original Carolingian facade with its single door. He designed the facade of Saint-Denis to be an echo of the Roman Arch of Constantine with its three-part division and three large portals to ease the problem of congestion. The rose window is the earliest-known example above the West portal in France. The facade combines both round arches and pointed arches of the Gothic style.
Is there an answer to this question: Who chose to rebuild the great Church of Saint-Denis in about 1137?

Answer: Suger

QUES: According to the U.S. Census Bureau, in 2004, Miami had the third highest incidence of family incomes below the federal poverty line in the United States, making it the third poorest city in the USA, behind only Detroit, Michigan (ranked #1) and El Paso, Texas (ranked #2). Miami is also one of the very few cities where its local government went bankrupt, in 2001. However, since that time, Miami has experienced a revival: in 2008, Miami was ranked as "America's Cleanest City" according to Forbes for its year-round good air quality, vast green spaces, clean drinking water, clean streets and city-wide recycling programs. In a 2009 UBS study of 73 world cities, Miami was ranked as the richest city in the United States (of four U.S. cities included in the survey) and the world's fifth-richest city, in terms of purchasing power.

In what year did Miami's government declare bankruptcy?
What is the answer?

2001
