Problem:Question: What war ended after the treaty where the village became part of Romania and fell within Ciuc County? Passage 1:The village was historically part of the Székely Land region of Transylvania province. The first reports of settlers in the area was from 1721. It became independent from Gyimesbükk in 1795. The birth registry starts from 1854. The village belonged to Csíkszék district until the administrative reform of Transylvania in 1876, when they fell within the Csík County in the Kingdom of Hungary. After the Treaty of Trianon of 1920, they became part of Romania and fell within Ciuc County during the interwar period. In 1940, the second Vienna Award granted the Northern Transylvania to Hungary and the villages were held by Hungary until 1944. After Soviet occupation, the Romanian administration returned and the commune became officially part of Romania in 1947. Between 1952 and 1960, the commune fell within the Magyar Autonomous Region, between 1960 and 1968 the Mureș-Magyar Autonomous Region. In 1968, the province was abolished, and since then, the commune has been part of Harghita County.
 Passage 2:He went out with the Baptist Missionary Society as a missionary doctor in 1935 to Pimu hospital, DRC in what was then the Belgian Congo. He was at Pimu Hospital, Province of Équateur until 1946, most of the time as the only doctor there (TLM, The Leprosy Mission started working there in 1944). He remained in the Belgian Congo in World War II. In 1930 there had been 30 Protestant missionaries in the Congo, but by 1939 Dr. Price was one of only five left. Although Belgium had been invaded by the Nazis, the Belgian government in exile in London continued to control the Congo and its valuable resources. In 1944 he published a paper on the grammar of the Ngombe language (one of the languages of Equateur Province) and thereafter contributed to the updating of the British and Foreign Bible Society's 1930 Ngombe New Testament, which was republished in 1956. In 1947 he was sent on a sabbatical to the UK by the Baptist Missionary Society to specialise as an orthopaedic surgeon (FRCS Ed. 1947). Returning to the Congo he went first to Sona Bata mission (part of the American Foreign Baptist Mission Society (A.F.B.M.S.), now American Baptist International Ministries), which already had a medical aide training school, and where he was tasked with helping to build Kimpese hospital. Kimpese hospital was set up by the protestant missions in the Congo as an interdenominational training hospital for medical auxiliaries. A Protestant hospital at Kimpese had first been mooted in 1923 (there had been an Evangelical training Institute there since 1909), but was strongly resisted by the Roman Catholic Church.. Before the war, the Belgian colonial government had refused to subsidise any Protestant educational enterprise, even the training of medical aides (the sole exception was the BMS medical aides training school at Yakusu). After the war this policy was reversed by the Socialist governments of Achille Van Acker and Protestant establishments were subsidised on the same basis as Catholic ones. As a result the Protestant IME (Institut Medical Evangelique) Kimpese could be opened. He was at IME Kimpese as an orthopaedic surgeon 1947-1956. He was succeeded in this post, as he had been at Pimu by Dr David Hedley Wilson, later the first President of the Royal college of Emergency Medicine. IME Kimpese "became rapidly known throughout the lower Congo river and beyond for the high standard of its nursing school and hospital". During this time, he developed an interest in the rehabilitation of leprosy patients.
 Passage 3:Aram Sarkissian (Simon Abkarian) is a young French-Armenian member of AGJSA, an Armenian militant organization, who leaves his family in Paris to fight in the Nagorno-Karabakh War. In October 1993, Aram returns to France to live a "normal life" again, but finds his younger brother Levon (Mathieu Demy) preparing the assassination of Azbalan Djelik, a general of the Turkish Army visiting France. Aram opposes the assassination, claiming the Armenian struggle lies in Nagorno-Karabakh, however, Levon considers Aram to be a coward, who then reluctantly agrees. One evening, General Djelik is killed when his car is ambushed by 3 masked gunmen, who shoot and kill three of the four passengers. The survivor, Djelik's aide-de-camp Colonel Talaat Sonlez (Serge Avédikian), shoots Levon after he pretended to be dead. Levon is immobilized and enters a coma, and Sonlez is shot by the Armenians before they flee. AGJSA claims responsibility for the attack, justifying it as General Djelik was a high-ranking member of the Black Wolves, a Turkish ultranationalist organization. Talaat survives again, and searches for the assassins by asking Monsieur Paul (Gilles Arbona), a French counter-terrorism policeman monitoring the activities of AGJSA, who does not reveal their identities.
