PROBLEM: Passage: The population of Western Asia was estimated at 272 million as of 2008, projected to reach 370 million by 2030 by Maddison . This corresponds to an annual growth rate of 1.4% , well above the world average of 0.9% .The population of Western Asia is estimated at about 4% of world population, up from about 39 million at the beginning of the 20th century, or about 2% of world population at the time. The most populous countries in the region are Turkey and Iran and, each with around 79 million people, followed by Iraq and Saudi Arabia with around 33 million people each. Numerically, Western Asia is predominantly Arab, Persian, Turkish, and the dominating languages are correspondingly Arabic, Persian and Turkish, each with of the order of 70 million speakers, followed by smaller communities of Kurdish, Azerbaijani, Hebrew, Armenian and Eastern Aramaic. The dominance of Arabic and Turkish is the result of the medieval Arab and Turkic invasions beginning with the Islamic conquests of the 7th century AD, which displaced the formerly dominant Aramaic and Hebrew in the Levant, and Greek in Anatolia, although Hebrew is once again the dominant language in Israel, and Aramaic  and Greek both remain present in their respective territories as minority languages. Other significant native minorities include Assyrians, Druze, Jews, Mandeans, Maronites, Shabaks, Syriac Arameans, Lurs and Yezidis. 
Question: How many percent larger is the annual growth rate in Western Asia than the rest of the world? 
Answer type: Number 

SOLUTION: .5.

PROBLEM: 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 

SOLUTION: 2.

PROBLEM: Passage: Week 10 featured the top-ranked defenses (by yardage against) in each conference, as the Lions hosted the Dolphins. Detroit got off to a quick start. Matt Prater kicked a 26-yard field goal on the opening drive of the game. Later in the first quarter, Calvin Johnson, playing in his first game since Week 5, caught a 49-yard TD pass from Matthew Stafford for a 10-0 lead. Miami managed a 23-yard Caleb Sturgis field goal before halftime, making the score 10-3. The Dolphins took the lead in the third, starting with a 50-yard Stugis field goal. Next, Earl Mitchell blocked Prater's 42-yard field goal attempt, and Dion Jordan returned the ball to the Lions 3-yard line. On the next play, Ryan Tannehill connected with Mike Wallace for the touchdown, putting Miami ahead, 13-10. Prater made good on a 50-yard field goal early in the fourth quarter to knot the score at 13-13, but Sturgis' 20-yarder put Miami back on top by 3. As in the previous two games, the Lions had to rally on their final drive to win the game. Starting at their own 26 with 3:13 left in the game, the drive culminated with Stafford's 11-yard touchdown pass to Theo Riddick, putting the Lions ahead for good, 20-16. This was the third straight game in which the Lions trailed at the two-minute warning, then went ahead on their final drive. It was the second time in a month that Miami had lost a game in the final seconds, following a Week 7 loss to Green Bay in which the final touchdown was scored with 3 seconds remaining. According to STATS Inc., this is the first time Detroit has started a season 7-2 since 1993.
