P: In the north of the region is the Sailughem Mountains, also known as Kolyvan Altai, which stretch northeast from 49 N and 86 E towards the western extremity of the Sayan Mountains in 51 60 N and 89 E. Their mean elevation is 1,500 to 1,750 m. The snow-line runs at 2,000 m on the northern side and at 2,400 m on the southern, and above it the rugged peaks tower some 1,000 m higher. Mountain passes across the range are few and difficult, the chief being the Ulan-daban at 2,827 m (2,879 m according to Kozlov), and the Chapchan-daban, at 3,217 m, in the south and north respectively. On the east and southeast this range is flanked by the great plateau of Mongolia, the transition being effected gradually by means of several minor plateaus, such as Ukok plateau (2,380 m) with Pazyryk Valley, Chuya (1,830 m), Kendykty (2,500 m), Kak plateau (2,520 m), (2,590 m), and (2,410 m).
Answer this: By how many meters does the mean elevation of the Kolyvan Altai vary?

A: 250

Problem: The Jets faced a tough matchup in the Pittsburgh Steelers, who possessed the top-ranked defense in the league entering the game. The Jets started the game with a bang, however, executing a flea flicker play as quarterback Kellen Clemens found Laveranues Coles for 57yards, setting up Chris Baker's one-yard touchdown reception. After the Jets extended their lead to ten points, the Steelers got on the board in the second quarter. Quarterback Ben Roethlisberger found Santonio Holmes on a seven-yard pass for a touchdown, making the score 10-7. Later, following a Roethlisberger interception by Kerry Rhodes, Clemens led the Jets through a two-minute drill down to the Steelers' one-yard line, but could not get into the end zone, and the Jets settled for a Mike Nugent 19-yard field goal. The Steelers were able to chip away at the deficit in the second half. Though the Jets defense managed to stall Pittsburgh drives into Jets territory, Jeff Reed hit field goal attempts from 37, 33, and 48yards to eventually give Pittsburgh a 16-13 lead with less than nine minutes to go. The Jets eventually received the ball at their own 14-yard line with 2:23 left in the game, and for the second game in a row, Clemens marched the team downfield, on a 13-play, 76-yard drive, culminating in a 28-yard field goal attempt for Nugent, which forced overtime. After both teams went three-and-out to start, Leon Washington, who Pittsburgh kickers and punters had avoided kicking to for much of the game, returned a punt 33yards to the Steelers 27-yard line. This set up Nugent's successful 38-yard field goal, giving the Jets their second win of the season. The Jets defense had an impressive game; in addition to an interception and a fumble recovery, they were able to pressure Roethlisberger throughout the game, resulting in seven quarterback sacks, after having just nine in the team's first nine games.

How many field goals between 30 and 40 yards were made?
Answer: 3

Q: This time, Pagan could not do anything to retake Martaban because it was facing an existential threat from the north. The Mongols demanded tribute, in 1271 and again in 1273. When Narathihapate refused both times, the Mongols systematically invaded the country. The first invasion in 1277 defeated the Burmese at the battle of Ngasaunggyan, and secured their hold of Kanngai . In 1283-1285, their forces moved south and occupied down to Tagaung and Hanlin. The king fled to Lower Burma in 1285 before agreeing to submit to the Mongols in June 1286. Soon after the agreement was finalised, the king was assassinated in July 1287. The Mongols once again invaded south toward Pagan. Recent research indicates that Mongol armies may not have reached Pagan itself, and that even if they did, the damage they inflicted was probably minimal. But the damage was already done. All the vassal states of Pagan revolted right after the king's death, and went their own way. In the south, Wareru, the man who had seized the governorship of Martaban in 1281, consolidated Mon-speaking regions of Lower Burma, and declared Ramannadesa independent. In the west too, Arakan stopped paying tribute. The 250-year-old Pagan Empire had ceased to exist.
How many years passed between the first and second times that the Mongols demanded tribute?
A: 2

P: After the defeat of the Guarani rebels, the Spanish and Portuguese forced the Guarani to abandon the seven reductions that had been ceded to Portugal in the Treaty of Madrid and to move to Spanish controlled lands. According to a census conducted in 1756 the population of the Guarani from the seven missions was 14,284, which was about 15,000 less than the population in 1750. The former Jesuit missions were occupied by the Portuguese-Brazilians until 1759 when Spain unilaterally ended the Treaty of Madrid and reclaimed the lands of the seven missions. The border of the La Plata colonial region was finalized by the Treaty of San Ildefonso in 1777.
Answer this: How many years did it take the population of Guarani to reduce?

A:
