Input: Question: Which countries were both a member of the European Union and the Council of Europe when Albania was accepted into the Council of Europe? Passage 1:Adair fought in the First World War. He joined the British Army, receiving his commission as a probationary second lieutenant on 2 May 1916 in the 5th (Reserve) Battalion of the Grenadier Guards. From January 1917 onwards he served in the trenches of the Western Front in France and Belgium as part of the 2nd Company, 3rd Battalion, Grenadier Guards, with the rank of lieutenant. The battalion was part of the 2nd Guards Brigade of the Guards Division. Adair's first major battle was in the pursuit of the retreating German Army to the Hindenburg Line. The division then took part in the Battle of Passchendaele. Adair, however, took no part in the battle, due to an injury sustained in a bicycle accident in early July 1917. He returned to the battalion in January 1918.
Passage 2:In 1991, the Socialist Party of Albania, with specific social democratic ideology took control of the country through democratic elections. One year later the Democratic Party of Albania won the new elections. After 1990, Albania has been seeking a closer relationship with the West. What followed were deliberate programs of economic and democratic reform, but Albanian inexperience with capitalism led to the proliferation of pyramid schemes which were not banned due to the corruption of the government. Chaos in late 1996 to early 1997, as a result of the collapse of these pyramid schemes, alarmed the world and prompted the influx of international peacekeeping forces. In 1995, Albania was accepted into the Council of Europe and requested membership in NATO (obtained in 2009) and is a potential candidate country for accession to the European Union. The workforce of Albania has continued to emigrate to Western countries, especially Greece and Italy.
Passage 3:Meanwhile, at Oscarsborg Fortress near Drbak, Colonel Birger Eriksen prepares his undermanned and inexperienced garrison for combat, while receiving reports from the outlying fortresses of incoming German ships. Early on the morning of 9 April, Eriksen spots the German cruiser Blucher entering Drbak Sound. Despite having received no instructions from Oslo to engage, Eriksen considers the German ship to be hostile and gives the order to fire, and the fortress's guns and torpedo battery sink the Blucher. Prime Minister Nygaardsvold telephones the King, informing him of the impending invasion, and advises him to flee Oslo. The Royal Family boards a train for Hamar, where the Norwegian Parliament convenes to discuss negotiations with Germany. Brauer meets Oslo's police chief Kristian Welhaven, his intermediary with the Norwegian Cabinet, to reassure them of his desire to negotiate; at the same time, Pohlman receives orders from Berlin to send paratroopers to Hamar to capture the King and the Cabinet. Nasjonal Samling leader Vidkun Quisling proclaims himself Prime Minister over the national radio, and calls upon the Norwegian people to accept the German occupation forces. Brauer receives instructions from Hitler himself to go directly to the King and convince him to recognise Quisling's government, though Brauer is convinced that neither Haakon nor the Cabinet will accept this.
