TASK DEFINITION: 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.
PROBLEM: Passage: In January 1918, Romanian forces established control over Bessarabia as the Russian Army abandoned the province. Although a treaty was signed by the Romanian and Bolshevik Russian governments following talks between 5 and 9 March 1918 on the withdrawal of Romanian forces from Bessarabia within two months, on 27 March 1918 Romania formally attached Bessarabia to its territory, based on a resolution passed by the local assembly of that territory on its unification with Romania. Romania officially made peace with the Central Powers by signing the Treaty of Bucharest on 7 May 1918. Under the treaty, Romania was obliged to end the war with the Central Powers and make small territorial concessions to Austria-Hungary, ceding control of some passes in the Carpathian Mountains, and to grant oil concessions to Germany. In exchange, the Central Powers recognised the sovereignty of Romania over Bessarabia. The treaty was renounced in October 1918 by the Alexandru Marghiloman government, and Romania nominally re-entered the war on 10 November 1918. The next day, the Treaty of Bucharest was nullified by the terms of the Armistice of Compiègne. Total Romanian deaths from 1914 to 1918, military and civilian, within contemporary borders, were estimated at 748,000.
Question: How many days did the talks between Russians and Romanians last?

SOLUTION: number

PROBLEM: Passage: In 1922, the Bolsheviks closed down the Novodevichy Convent  and turned it into the Museum of Women's Emancipation. By 1926, the monastery had been transformed into a history and art museum. In 1934, it became affiliated with the State Historical Museum. Most of its facilities were turned into apartments, which spared the convent from destruction. In 1943, when Stalin started to make advances to the Russian Orthodox Church during World War II, he sanctioned opening the Moscow Theological Courses at the convent. Next year the program was transformed and became the Moscow Theological Institute. In 1945, the Soviets returned Assumption Cathedral to the believers. The residence of the Metropolitan of Krutitsy and Kolomna has been located in the Novodevichy Convent since 1980. In 1994, nuns returned to the convent, which is currently under the authority of the Metropolitan of Krutitsy and Kolomna. Some of the churches and other monastic buildings are still affiliated with the State Historical Museum. In 1995, religious services resumed in the convent on patron saint's days.
Question: Which year did Moscow Theological Program transform and become the Moscow Theological Institute?

SOLUTION: date

PROBLEM: Passage: Before the Monthon reforms initiated by king Chulalongkorn, Siamese territories were divided into three categories: Inner Provinces forming the core of the kingdom, Outer Provinces that were adjacent to the inner provinces and tributary states located on the border regions. The area of southern Laos that came under Siamese control following the Lao rebellion  and destruction of Vientiane belonged to the later category, maintaining relative autonomy. Lao nobles who had received the approval of the Siamese king exercised authority on the Lao population as well as the Alak and Laven-speaking tribesmen. Larger tribal groups often raided weaker tribes abducting people and selling them into slavery at the trading hub of Champasak, while themselves falling prey to Khmer, Lao and Siamese slavers. From Champasak the slaves were transported to Phnom-Penh and Bangkok, thus creating a large profits for the slavers and various middlemen. In 1874 and 1884, king Chulalongkorn enacted two decrees banning the capture and sale of Kha slaves while also freeing all slaves born after 1868. Those abolitionist policies had an immediate effect on slave trading communities. In 1883, France attempted to expand its control in Southeast Asia by claiming that the Treaty of Huế extended into all Vietnamese vassal states. French troops gradually occupied the Kontum Plateau and pushed the Siamese from Laos following the Franco-Siamese War. A new buffer zone was thus created on the west bank of Mekong, as the area lacked the presence of the Siamese military local outlaws flocked the newly created safe haven. In 1899, Siam abolished the tributes collected from vassal states, replacing them with a new tax collected from all able bodied men, undermining the authority of Lao officials. The combined effects of the abolitionist laws and taxation led the Lao and Kha  nobility into an open rebellion.
Question: In which year was King Chulalongkorn's first decree banning the capture and sale of Kha slaves?
