PROBLEM: story: Ultratop is an organization which generates and publishes the official record charts in Belgium, and it is also the name of most of those charts. Ultratop is a non-profit organization, created on the initiative of the Belgian Entertainment Association (BEA), the Belgian member organization of the International Federation of the Phonographic Industry. Two parallel set of charts are concurrently produced and published, one on behalf of Belgium's Dutch-speaking Flanders region, and the other catering to the nation's French-speaking region of Wallonia. 

The music charts produced by Ultratop organization are separated along regional-language boundaries, an unusual division that is justified by the cultural differences in Belgium. So it is that the Dutch-speaking Flanders region has one set of charts of record activity there, while the French-speaking Wallonia region has another set to measure popularity in those provinces. 

The charts are broadcast on several Belgian radio stations, and on TV stations TMF in Flanders and Plug RTL in Wallonia. 

Ultratop creates charts based on record sales of around 500 retail outlets and legal digital downloads. Currently GfK is the market observer of the charts. The chart broadcasts on Radio Contact on Saturdays from 12:00 to 14:00. The combined number of Ultratop chart listeners on the various radio or TV stations exceeds two million every week. To celebrate the 10th anniversary of the charts in 2005, a jubilee book was published. It covers all 15,282 singles from 5,882 artists thus far., question: By what, in Belgium?

SOLUTION: the cultural differences

PROBLEM: story: CHAPTER XXXVI. 

TOM TRINGLE GETS AN ANSWER. 

Faddle as he went down into the country made up his mind that the law which required such letters to be delivered by hand was an absurd law. The post would have done just as well, and would have saved a great deal of trouble. These gloomy thoughts were occasioned by a conviction that he could not carry himself easily or make himself happy among such "howling swells" as these Alburys. If they should invite him to the house the matter would be worse that way than the other. He had no confidence in his dress coat, which he was aware had been damaged by nocturnal orgies. It is all very well to tell a fellow to be as "big a swell" as anybody else, as Tom had told him. But Faddle acknowledged to himself the difficulty of acting up to such advice. Even the eyes of Colonel Stubbs turned upon him after receipt of the letter would oppress him. 

Nevertheless he must do his best, and he took a gig at the station nearest to Albury. He was careful to carry his bag with him, but still he lived in hope that he would be able to return to London the same day. When he found himself within the lodges of Stalham Park he could hardly keep himself from shivering, and, when he asked the footman at the door whether Colonel Stubbs were there, he longed to be told that Colonel Stubbs had gone away on the previous day to some--he did not care what--distant part of the globe. But Colonel Stubbs had not gone away. Colonel Stubbs was in the house. , question: What was he hoping?

SOLUTION: That Colonel Stubbs had gone away.

PROBLEM: story: Berlin is the capital and the largest city of Germany as well as one of its 16 constituent states. With a population of approximately 3.7 million, Berlin is the second most populous city proper in the European Union and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of the rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has roughly 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers, canals and lakes. 

First documented in the 13th century and situated at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg (14171701), the Kingdom of Prussia (1701–1918), the German Empire (1871–1918), the Weimar Republic (1919–1933) and the Third Reich (1933–1945). Berlin in the 1920s was the third largest municipality in the world. After World War II and its subsequent occupation by the victorious countries, the city was divided; East Berlin was declared capital of East Germany, while West Berlin became a de facto West German exclave, surrounded by the Berlin Wall (1961–1989) and East German territory. Following German reunification in 1990, Berlin once again became the capital of all of Germany., question: When was the city divided?

SOLUTION:
After World War II
