Problem: Estimates of the recognized Greek Muslim minority, which is mostly located in Thrace, range from 98,000 to 140,000, (about 1%) while the immigrant Muslim community numbers between 200,000 and 300,000. Albanian immigrants to Greece are usually associated with the Muslim religion, although most are secular in orientation. Following the 19191922 Greco-Turkish War and the 1923 Treaty of Lausanne, Greece and Turkey agreed to a population transfer based on cultural and religious identity. About 500,000 Muslims from Greece, predominantly those defined as Turks, but also Greek Muslims like the Vallahades of western Macedonia, were exchanged with approximately 1,500,000 Greeks from Turkey. However, many refugees who settled in former Ottoman Muslim villages in Central Macedonia and were defined as Christian Orthodox Caucasus Greeks arrived from the former Russian Transcaucasus province of Kars Oblast after it had been retroceded to Turkey but in the few years before the official population exchange.
What is the religious minority in Greece?
The answer is the following: Muslim

Problem: Soon after the victory in U-Tsang, Gushi Khan organized a welcoming ceremony for Lozang Gyatso once he arrived a day's ride from Shigatse, presenting his conquest of Tibet as a gift to the Dalai Lama. In a second ceremony held within the main hall of the Shigatse fortress, Gushi Khan enthroned the Dalai Lama as the ruler of Tibet, but conferred the actual governing authority to the regent Sonam Chopel. Although Gushi Khan had granted the Dalai Lama "supreme authority" as Goldstein writes, the title of 'King of Tibet' was conferred upon Gushi Khan, spending his summers in pastures north of Lhasa and occupying Lhasa each winter. Van Praag writes that at this point Gushi Khan maintained control over the armed forces, but accepted his inferior status towards the Dalai Lama. Rawski writes that the Dalai Lama shared power with his regent and Gushi Khan during his early secular and religious reign. However, Rawski states that he eventually "expanded his own authority by presenting himself as Avalokitesvara through the performance of rituals," by building the Potala Palace and other structures on traditional religious sites, and by emphasizing lineage reincarnation through written biographies. Goldstein states that the government of Gushi Khan and the Dalai Lama persecuted the Karma Kagyu sect, confiscated their wealth and property, and even converted their monasteries into Gelug monasteries. Rawski writes that this Mongol patronage allowed the Gelugpas to dominate the rival religious sects in Tibet.
Who did Gushi Khan organize a welcome ceremony for?
The answer is the following: Lozang Gyatso

Problem: The establishment of Ottoman military aviation dates back to between June 1909 and July 1911. The Ottoman Empire started preparing its first pilots and planes, and with the founding of the Aviation School (Tayyare Mektebi) in Yesilkoy on 3 July 1912, the Empire began to tutor its own flight officers. The founding of the Aviation School quickened advancement in the military aviation program, increased the number of enlisted persons within it, and gave the new pilots an active role in the Ottoman Army and Navy. In May 1913 the world's first specialized Reconnaissance Training Program was started by the Aviation School and the first separate reconnaissance division was established.[citation needed] In June 1914 a new military academy, the Naval Aviation School (Bahriye Tayyare Mektebi) was founded. With the outbreak of World War I, the modernization process stopped abruptly. The Ottoman aviation squadrons fought on many fronts during World War I, from Galicia in the west to the Caucasus in the east and Yemen in the south.
What happened at the aviation school in May 1913?
The answer is the following: the world's first specialized Reconnaissance Training Program was started
