Problem: Federalism:

The meaning of federalism, as a political movement, and of what constitutes a 'federalist', varies with country and historical context.[citation needed] Movements associated with the establishment or development of federations can exhibit either centralising or decentralising trends.[citation needed] For example, at the time those nations were being established, factions known as "federalists" in the United States and Australia advocated the formation of strong central government. Similarly, in European Union politics, federalists mostly seek greater EU integration. In contrast, in Spain and in post-war Germany, federal movements have sought decentralisation: the transfer of power from central authorities to local units. In Canada, where Quebec separatism has been a political force for several decades, the "federalist" impulse aims to keep Quebec inside Canada.

Problem: A collector of film memorabilia, Spielberg purchased a balsa Rosebud sled from Citizen Kane (1941) in 1982. He bought Orson Welles's own directorial copy of the script for the radio broadcast The War of the Worlds (1938) in 1994. Spielberg has purchased Academy Award statuettes being sold on the open market and donated them to the Academy of Motion Picture Arts and Sciences, to prevent their further commercial exploitation. His donations include the Oscars that Bette Davis received for Dangerous (1935) and Jezebel (1938), and Clark Gable's Oscar for It Happened One Night (1934).

In response to the demonstrations, the Chinese government attempted to calm the situation, possibly fearing the protests may spiral out of control as has happened in recent years, including the anti-Japanese protests in 2005. State media and commentaries began to call for calm, such as an editorial in the People's Daily which urged Chinese people to "express [their] patriotic enthusiasm calmly and rationally, and express patriotic aspiration in an orderly and legal manner". The government also began to patrol and censor the internet forums such as Sohu.com, with comments related to the Carrefour boycott removed. In the days prior to the planned boycott, evidence of efforts by Chinese authorities to choke the mass boycott's efforts online became even more evident, including barring searches of words related to the French protests, but protests broke out nonetheless in front of Carrefour's stores at Beijing, Changsha, Fuzhou and Shenyang on May 1.
Which website had mentions of the Carrefour boycott removed by the government?
A: Sohu.com

Context and question: In 2004, madaris were mainstreamed in 16 Regions nationwide, primarily in Muslim-majority areas in Mindanao under the auspices of the Department of Education (DepEd). The DepEd adopted Department Order No. 51, which instituted Arabic-language and Islamic Values instruction for Muslim children in state schools, and authorised implementation of the Standard Madrasa Curriculum (SMC) in private-run madaris. While there are state-recognised Islamic schools, such as Ibn Siena Integrated School in the Islamic City of Marawi, Sarang Bangun LC in Zamboanga and SMIE in Jolo, their Islamic studies programmes initially varied in application and content.
How many regions outside of Singapore have widely accepted madaris?
Answer: unanswerable

Question: The use of alloys by humans started with the use of meteoric iron, a naturally occurring alloy of nickel and iron. It is the main constituent of iron meteorites which occasionally fall down on Earth from outer space. As no metallurgic processes were used to separate iron from nickel, the alloy was used as it was. Meteoric iron could be forged from a red heat to make objects such as tools, weapons, and nails. In many cultures it was shaped by cold hammering into knives and arrowheads. They were often used as anvils. Meteoric iron was very rare and valuable, and difficult for ancient people to work.
Is there an answer to this question: What was used to separate the iron and nickelin meteoric iron? And

Answer: unanswerable

Question: While the times of sunrise and sunset change at roughly equal rates as the seasons change, proponents of Daylight Saving Time argue that most people prefer a greater increase in daylight hours after the typical "nine-to-five" workday. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, but the actual effect on overall energy use is heavily disputed.
Is there an answer to this question: What word describes the approximate rates at which sunset and sunrise change with the seasons?

equal
