Problem: Neptune:

In 1821, Alexis Bouvard published astronomical tables of the orbit of Neptune's neighbour Uranus. Subsequent observations revealed substantial deviations from the tables, leading Bouvard to hypothesise that an unknown body was perturbing the orbit through gravitational interaction. In 1843, John Couch Adams began work on the orbit of Uranus using the data he had. Via Cambridge Observatory director James Challis, he requested extra data from Sir George Airy, the Astronomer Royal, who supplied it in February 1844. Adams continued to work in 184546 and produced several different estimates of a new planet.

When did John Couch Adams begin working on the orbit of Neptune?

Problem: United States presidential election, 2004:

Just eight months into his presidency, the terrorist attacks of September 11, 2001 suddenly transformed Bush into a wartime president. Bush's approval ratings surged to near 90%. Within a month, the forces of a coalition led by the United States entered Afghanistan, which had been sheltering Osama bin Laden, suspected mastermind of the September 11 attacks. By December, the Taliban had been removed as rulers of Kabul, although a long and ongoing reconstruction would follow, severely hampered by ongoing turmoil and violence within the country.

By which month, were the Taliban no longer controlling Kabul?
---
A: December

Problem: The Sun (United Kingdom):

In exchange for Rupert Murdoch's support, Blair agreed not to join the European Exchange Rate Mechanism which John Major had withdrawn the country from in September 1992 after barely two years. Cabinet Minister Peter Mandelson was "outed" by Matthew Parris (a former Sun columnist) on BBC TV's Newsnight in November 1998. Misjudging public response, The Sun's editor David Yelland demanded to know in a front page editorial whether Britain was governed by a "gay mafia" of a "closed world of men with a mutual self-interest". Three days later the paper apologised in another editorial which said The Sun would never again reveal a person's sexuality unless it could be defended on the grounds of "overwhelming public interest".

What did The Sun say its policy about revealing an individual's sexuality would be moving forward?
---
A: The Sun would never again reveal a person's sexuality unless it could be defended on the grounds of "overwhelming public interest"

Problem: Utrecht:

In 1528 the bishop lost secular power over both Neder- and Oversticht which included the city of Utrecht to Charles V, Holy Roman Emperor. Charles V combined the Seventeen Provinces (the current Benelux and the northern parts of France) as a personal union. This ended the prince-bishopric Utrecht, as the secular rule was now the lordship of Utrecht, with the religious power remaining with the bishop, although Charles V had gained the right to appoint new bishops. In 1559 the bishopric of Utrecht was raised to archbishopric to make it the religious center of the Northern ecclesiastical province in the Seventeen provinces.

What was the religious center of Norther Europe?
