[EX Q]: Passage: The size of the indemnity had been the hardest factor to accept for the Tibetan negotiators. The Secretary of State for India, St John Brodrick, had in fact expressed the need for it to be "within the power of the Tibetans to pay" and given Younghusband a free hand to be "guided by circumstances in this matter". Younghusband raised the indemnity demanded from 5,900,000 to 7,500,000 rupees, and further demanded the right for a British trade agent, based at Gyantse, to visit Lhasa "for consultations". It seems that he was still following Lord Curzon's geo-political agenda to extend British influence in Tibet by securing the Chumbi Valley for Britain.  Younghusband wanted the payment to be met by yearly instalments; it would have taken about 75 years for the Tibetans to clear their debt, and since British occupation of the Chumbi valley was surety until payment was completed, the valley would remain in British hands. Younghusband wrote to his wife immediately after the signing; "I have got Chumbi for 75 years. I have got Russia out for ever". The regent commented that "When one has known the scorpion  the frog  is divine". The Amban later publicly repudiated the treaty, while Britain announced that it still accepted Chinese claims of authority over Tibet. Acting Viceroy Lord Ampthill reduced the indemnity by two-thirds and considerably eased the terms in other ways. The provisions of this 1904 treaty were revised in the Anglo-Chinese Convention of 1906. The British, for a fee from the Qing court, also agreed "not to annex Tibetan territory or to interfere in the administration of Tibet", while China engaged "not to permit any other foreign state to interfere with the territory or internal administration of Tibet". 
Question: How many years were between the 1904 treaty and its revision? 
Answer type: Number

[EX Q]: Passage: Considering revenue alone, Inter surpassed city rivals in Deloitte Football Money League for the first time, in the 2008–09 season, to rank in 9th place, one place behind Juventus in 8th place. (Milan in 10th place.) In the 2009–10 season, Inter remained in 9th place, surpassing Juventus (10th) but Milan re-took the leading role as the 7th. Inter became the 8th in 2010–11, but was still one place behind Milan. Since 2011, Inter fell to 11th in 2011–12, 15th in 2012–13 and 17th in 2013–14 season. In 2008–09 season, Revenue percentages were divided up between matchday (14%, €28.2 million), broadcasting (59%, €115.7 million, +7%, +€8 million) and commercial (27%, €52.6 million, +43%). Kit sponsors Nike and Pirelli contributed €18.1 million and €9.3 million respectively to commercial revenues, while broadcasting revenues were boosted €1.6 million (6%) by Champions League distribution. in 2009–10 season the revenue was boosted by the sales of Zlatan Ibrahimović, the Treble (association football) and the release clause of coach José Mourinho. For the 2010–11 season, Serie A clubs started negotiating club TV rights collectively rather than individually. This was predicted to result in lower broadcasting revenues for Inter, with smaller clubs gaining from the loss. Eventually the result included an extraordinary income of €13 million from RAI. Deloitte expressed the idea that issues in Italian football, particularly matchday revenue issues were holding Inter back compared to other European giants, and developing their own stadia would result in Serie A clubs being more competitive on the world stage. 
Question: How many more million €s did Nike contribute to commercial revenues compared to Pirelli? 
Answer type: Number

8.8.
