Problem: There has been much debate over categorizing the situation in Darfur as genocide. The ongoing conflict in Darfur, Sudan, which started in 2003, was declared a "genocide" by United States Secretary of State Colin Powell on 9 September 2004 in testimony before the Senate Foreign Relations Committee. Since that time however, no other permanent member of the UN Security Council followed suit. In fact, in January 2005, an International Commission of Inquiry on Darfur, authorized by UN Security Council Resolution 1564 of 2004, issued a report to the Secretary-General stating that "the Government of the Sudan has not pursued a policy of genocide." Nevertheless, the Commission cautioned that "The conclusion that no genocidal policy has been pursued and implemented in Darfur by the Government authorities, directly or through the militias under their control, should not be taken in any way as detracting from the gravity of the crimes perpetrated in that region. International offences such as the crimes against humanity and war crimes that have been committed in Darfur may be no less serious and heinous than genocide."
In front of which committee did Powell testify?
The answer is the following: the Senate Foreign Relations Committee

Problem: For example, the full name of Oda Nobunaga would be "Oda Kazusanosuke Saburo Nobunaga" (織田上総介三郎信長), in which "Oda" is a clan or family name, "Kazusanosuke" is a title of vice-governor of Kazusa province, "Saburo" is a formal nickname (yobina), and "Nobunaga" is an adult name (nanori) given at genpuku, the coming of age ceremony. A man was addressed by his family name and his title, or by his yobina if he did not have a title. However, the nanori was a private name that could be used by only a very few, including the Emperor.
What did Kazusanosuke mean?
The answer is the following: a title of vice-governor of Kazusa province

Problem: The 548 ft (167 m) City Hall remained the tallest building in the city until 1987 when One Liberty Place was constructed. Numerous glass and granite skyscrapers were built in Philadelphia's Center City from the late 1980s onwards. In 2007, the Comcast Center surpassed One Liberty Place to become the city's tallest building. The Comcast Innovation and Technology Center is under construction in Center City and is planned to reach a height of 1,121 feet (342 meters); upon completion, the tower is expected to be the tallest skyscraper in the United States outside of New York City and Chicago.
What is the tallest building?
The answer is the following: Comcast Center

Problem: This changed with the recent sovereign-debt crisis. The ECB always could, and through the late summer of 2011 did, purchase bonds issued by the weaker states even though it assumes, in doing so, the risk of a deteriorating balance sheet. ECB buying focused primarily on Spanish and Italian debt. Certain techniques can minimise the impact. Purchases of Italian bonds by the central bank, for example, were intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank.
Why were italian bonds purchased by the ECB?
The answer is the following:
intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank
