Problem: Background: Sven Anders Hedin, KNO1kl RVO, (19 February 1865 - 26 November 1952) was a Swedish geographer, topographer, explorer, photographer, travel writer, and illustrator of his own works. During four expeditions to Central Asia, he made the Transhimalaya known in the West and located sources of the Brahmaputra, Indus and Sutlej Rivers. He also mapped lake Lop Nur, and the remains of cities, grave sites and the Great Wall of China in the deserts of the Tarim Basin. In his book Fran pol till pol (From Pole to Pole), Hedin describes a journey through Asia and Europe between the late 1880s and the early 1900s.
Context: Hedin's conservative and pro-German views eventually translated into sympathy for the Third Reich, and this would draw him into increasing controversy towards the end of his life. Adolf Hitler had been an early admirer of Hedin, who was in turn impressed with Hitler's nationalism. He saw the German leader's rise to power as a revival of German fortunes, and welcomed its challenge against Soviet Communism. He was not an entirely uncritical supporter of the Nazis, however. His own views were shaped by traditionalist, Christian and conservative values, while National Socialism was in part a modern revolutionary-populist movement. Hedin objected to some aspects of National Socialist rule, and occasionally attempted to convince the German government to relent in its anti-religious and anti-Semitic campaigns.  Hedin met Adolf Hitler and other leading National Socialists repeatedly and was in regular correspondence with them. The politely-worded correspondence usually concerned scheduling matters, birthday congratulations, Hedin's planned or completed publications, and requests by Hedin for pardons for people condemned to death, and for mercy, release and permission to leave the country for people interned in prisons or concentration camps. In correspondence with Joseph Goebbels and Hans Drager, Hedin was able to achieve the printing of the Daily Watchwords year after year.  The Nazis attempted to achieve a close connection to Hedin by bestowing awards upon him. They asked him to present an address on Sport as a Teacher at the 1936 Summer Olympics in Berlin's Olympic stadium. They made him an honorary member of the German-Swedish Union Berlin (German: Deutsch-Schwedischen Vereinigung Berlin e.V.) In 1938, they presented him with the City of Berlin's Badge of Honor (German: Ehrenplakette der Stadt Berlin). For his 75th birthday on 19 February 1940 they awarded him the Order of the German Eagle; shortly before that date it had been presented to Henry Ford and Charles Lindbergh. On New Year's Day 1943 they released the Oslo professor of philology and university rector Didrik Arup Seip from the Sachsenhausen concentration camp at Hedin's request in order to obtain Hedin's agreement to accept additional honors during the 470th anniversary of Munich University. On 15 January 1943, he received the Gold Medal of the Bavarian Academy of Sciences (Goldmedaille der Bayerischen Akademie der Wissenschaften). On 16 January 1943 he received an honorary doctorate from the faculty of natural sciences of Munich University. On the same day, the Nazis founded in his absence the Sven Hedin Institute for Inner Asian Research located at Mittersill Castle, which was supposed to serve the long-term advancement of the scientific legacy of Hedin and Wilhelm Filchner as Asian experts. However, it was instead misused by Heinrich Himmler as an institute of the Research Association for German Genealogical Inheritance (Forschungsgemeinschaft Deutsches Ahnenerbe e.V.). On 21 January 1943, he was requested to sign the Golden Book of the city of Munich.  Hedin supported the Nazis in his journalistic activities. After the collapse of Nazi Germany, he did not regret his collaboration with the Nazis because this cooperation had made it possible to rescue numerous Nazi victims from execution, or death in extermination camps.
Question: What did Hedin write about the Nazis?

Background: Remment Lucas "Rem" Koolhaas (Dutch pronunciation: [rem ko:lha:s]; born 17 November 1944) is a Dutch architect, architectural theorist, urbanist and Professor in Practice of Architecture and Urban Design at the Graduate School of Design at Harvard University. Koolhaas studied at the Architectural Association School of Architecture in London and at Cornell University in Ithaca, New York. Koolhaas is the founding partner of OMA, and of its research-oriented counterpart AMO based in Rotterdam, the Netherlands. In 2005, he co-founded Volume Magazine together with Mark Wigley and Ole Bouman.
Context: Following the signing of Treaties of Nice in May 2001, which made Brussels the de facto capital of the European Union, the then President of the European Commission, Romano Prodi and the Belgian Prime Minister Guy Verhofstadt invited Koolhaas to discuss the necessities and requirements of a European capital.  During these talks and as an impetus for further discussion, Koolhaas and his think-tank AMO - an independent part of OMA - suggested the development of a visual language. This idea inspired a series of drawings and drafts, including the "Barcode". The barcode seeks to unite the flags of the EU member countries into a single, colourful symbol. In the current European flag, there is a fixed number of stars. In the barcode however, new Member States of the EU can be added without space constraints. Originally, the barcode displayed 15 EU countries. In 2004, the symbol was adapted to include the ten new Member States.  Since the time of the first drafts of the barcode it has very rarely been officially used by commercial or political institutions. During the Austrian EU Presidency 2006, it was officially used for the first time. The logo was used for the EU information campaign, but was very negatively criticized. In addition to the initial uproar caused by the Estonian flag stripes being displayed incorrectly, the proposed flag failed to achieve its main objective as a symbol. Critics pointed the lack of capability to relate the signified (the mental concept, the European Union) with the signifier (the physical image, the stripes) as the major problem, as well as the presented justification for the order in which the color stripes were displayed (as every country in the EU should be regarded as equal in importance and priority).
Question: What was EU information campaign about?
Answer:
The barcode seeks to unite the flags of the EU member countries into a single, colourful symbol.
