This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

[EX Q]: Passage: On 21 June, the HV attacked RSK positions at the Miljevci Plateau, located in the pink zone north of Šibenik. The TO forces in the area were subordinated to the 1st Brigade of the TO, and Lieutenant Colonel General Milan Torbica. The HV deployed 250 troops, elements of the 113th and 142nd Infantry Brigades, commanded by Brigadier Kruno Mazalin. The HV had infiltrated the pink zone along three routes—via Nos Kalik, across the Čikola river and by boat sailing upstream along the Krka River, during the night of 20/21 June. The fighting began at 5 a.m. as the HV force, deployed in 26 squads, captured six out of seven villages on the plateau by the end of the morning. At 8:00 p.m., the HV captured the village of Ključ, and all of the plateau. The advance created a HV-held salient south of Knin, several kilometres deep. It also led the RSK artillery to bombard Šibenik and HV bombardment of Knin in response, both on 22 June. The artillery fire progressively intensified until 23 June, while the RSK mobilised and counterattacked against the HV positions at the Miljevci Plateau. However, the mobilisation yielded only 227 additional troops, and the counterattack failed. An UNPROFOR assessment concluded the situation might deteriorate further and engulf all of the pink zones. To address the situation, UNPROFOR military commander Lieutenant General Satish Nambiar met with Deputy Prime Minister of Croatia Milan Ramljak and Chief of the General Staff of the Armed Forces of the Republic of Croatia General Anton Tus in Zagreb the same day, in order to discuss the developments on the Miljevci Plateau. Skirmishes continued on 24 June, accompanied by some artillery fire. Morale of the RSK troops plummeted though, causing a TO garrison based in nearby Trbounj to abandon its barracks.

[EX Q]: Passage: The 1910 Chinese expedition to Tibet or the Chinese invasion of Tibet in 1910 was a military campaign of the Qing dynasty to establish direct rule in Tibet in early 1910. The expedition occupied Lhasa on February 12 and officially deposed the 13th Dalai Lama on the 25th. Qing rule of Tibet was established in the early 18th century after the 1720 Chinese expedition to Tibet, but it was essentially a protectorate rather than a direct rule. The actual rule also waned considerably with the gradual weakening of the Qing dynasty in the 19th century. After the British expedition to Tibet in 1904 and the Sino-British treaty in 1906, the Qing decided to establish direct rule over Tibet and thus sent such an expedition in 1910. As Professor Dawa Norbu stated, "The British military expedition and subsequent convention made the Chinese realize that their power in Tibet had disappeared. So, in 1910 China invaded Tibet, and the Dalai Lama fled to India." In the late winter of 1910, the Manchu government in Beijing was furious with the 13th Dalai Lama. His government, having witnessed the dissolution of its domains in Khams by Qing administrators, and fearing that the amban in Lhasa was going to eliminate its temporal authority, cut this imperial officer off from the sustenance that the Tibet government had guaranteed him in a prior agreement with the Qing court. When a relief column arrived in Lhasa from Sichuan to break the amban out of his isolation, the Dalai Lama fled for British India. However, the direct rule over Tibet proved short-lived: after the outbreak of the Xinhai Revolution and the Xinhai Lhasa turmoil in 1911-1912, Qing rule essentially ended in Lhasa and other parts of Tibet. All Qing forces left Tibet by the end of 1912.
Question: How many years were the Qing forces present in Tibet before leaving?
