The problem: Answer a question about this article:
Outside of the Netherlands and Belgium, the dialect around the German town of Kleve (South Guelderish) both historically and genetically belongs to the Dutch language. In Northeastern France, the area around Calais was historically Dutch-speaking (West Flemish) of which an estimated 20,000 daily speakers. The cities of Dunkirk, Gravelines and Bourbourg only became predominantly French-speaking by the end of the 19th century. In the countryside, until World War I, many elementary schools continued to teach in Dutch, and the Catholic Church continued to preach and teach the catechism in Flemish in many parishes.
It took until the end of what century for people in French cities like Gravelines to finally switch over to French from Dutch?

The problem: Answer a question about this article:
French cooperation was deemed necessary to the campaign, and Eisenhower encountered a "preposterous situation" with the multiple rival factions in France. His primary objective was to move forces successfully into Tunisia, and intending to facilitate that objective, he gave his support to François Darlan as High Commissioner in North Africa, despite Darlan's previous high offices of state in Vichy France and his continued role as commander-in-chief of the French armed forces. The Allied leaders were "thunderstruck" by this from a political standpoint, though none of them had offered Eisenhower guidance with the problem in the course of planning the operation. Eisenhower was severely criticized for the move. Darlan was assassinated on December 24 by Fernand Bonnier de La Chapelle. Eisenhower did not take action to prevent the arrest and extrajudicial execution of Bonnier de La Chapelle by associates of Darlan acting without authority from either Vichy or the Allies, considering it a criminal rather than a military matter. Eisenhower later appointed General Henri Giraud as High Commissioner, who had been installed by the Allies as Darlan's commander-in-chief, and who had refused to postpone the execution.
Who served as High Commissioner of North Africa after Darlan's death?
****
The answer: Henri Giraud


The problem: Answer a question about this article:
The State Council declared a three-day period of national mourning for the quake victims starting from May 19, 2008; the PRC's National Flag and Regional Flags of Hong Kong and Macau Special Administrative Regions flown at half mast. It was the first time that a national mourning period had been declared for something other than the death of a state leader, and many have called it the biggest display of mourning since the death of Mao Zedong. At 14:28 CST on May 19, 2008, a week after the earthquake, the Chinese public held a moment of silence. People stood silent for three minutes while air defense, police and fire sirens, and the horns of vehicles, vessels and trains sounded. Cars and trucks on Beijing's roads also came to a halt. People spontaneously burst into cheering "Zhongguo jiayou!" (Let's go, China!) and "Sichuan jiayou" (Let's go, Sichuan!) afterwards.
How long was the national mourning for the quake victims to last?
****
The answer: three-day period


The problem: Answer a question about this article:
Chapultepec Park houses the Chapultepec Castle, now a museum on a hill that overlooks the park and its numerous museums, monuments and the national zoo and the National Museum of Anthropology (which houses the Aztec Calendar Stone). Another piece of architecture is the Fine Arts Palace, a white marble theatre/museum whose weight is such that it has gradually been sinking into the soft ground below. Its construction began during the presidency of Porfirio Díaz and ended in 1934, after being interrupted by the Mexican Revolution in the 1920s. The Plaza of the Three Cultures in the Tlatelolco neighbourhood, and the shrine and Basilicas of Our Lady of Guadalupe are also important sites. There is a double-decker bus, known as the "Turibus", that circles most of these sites, and has timed audio describing the sites in multiple languages as they are passed.
Where is the National Museum of Anthropology located?
****
The answer:
Chapultepec Park
