PROBLEM: Passage: Since 1444 Si Jifa had repeatedly sent tribute to Ming asking for pardon to no avail. In March 1449, a combined army of 150,000 soldiers was amassed, and the fourth and final campaign to extirpate the Mong Mao threat was launched under the supervision of Wang Ji. The army quickly marched on Mong Yang, which harbored Si Jifa, and captured their strongholds. However Si Jifa managed to escape yet again, and the campaign ended inconclusively with the ruling Shan elite allowed to remain in Mong Yang so long as they never returned to Mong Mao. Sources disagree as to how Si Jifa met his end. One source claims he died in combat in 1449, another says he was captured by the king of Ava and held captive in exchange for Ming territory, and one Shan chronicle claims he reigned for another fifty years. While Mong Mao had been defeated and pacified, Si Jifa's son Si Hongfa continued to rule in Mong Yang and his successors would eventually go on to invade Ava in 1527. So in practice Si Lunfa's family survived as rulers in the neighboring state of Mong Yang under the close observation of Ming. The fourth campaign was also marred by lack of discipline, inefficient administration, and mismanagement of resources. On the first day of mobilization, the entire 150,000 strong army started marching all at once, and many were trampled to death. Food supplies were mismanaged and assigned to individual carriers disproportionate to their weight, and no proper plan for their distribution existed. Some soldiers committed suicide due to the conditions prevalent in the army. 
Question: How many years passed from when he was sending Ming tribute to when 150,000 soldiers were amassed? 
Answer type: Number 

SOLUTION: 5.

PROBLEM: Passage: Coming off a bad loss to the Philadelphia Eagles, the Jaguars looked to rebound against their division rival Indianapolis Colts. Indianapolis scored on its first possession as running back Joseph Addai ran it in from two yards out to make the score 7-0 Colts. After two touchdown runs by David Garrard and Maurice Jones-Drew, the Jaguars took the lead in the second quarter, 14-7. Their lead didn't last very long as quarterback Peyton Manning threw a seven-yard touchdown pass to tight end Dallas Clark, tying the game at 14 heading into halftime. The Jaguars regained the lead in the third quarter with Garrard finding tight end Marcedes Lewis for a fifteen-yard touchdown pass. Jacksonville took the lead 21-14. Once again, the Colts responded when Addai scored on a two-yard touchdown run tying the game at 21. With 2:13 left in the game, Garrard completed it to Maurice Jones-Drew for an eight-yard touchdown pass and the Jaguars took a 28-21 lead. That was enough time for 4 time MVP Peyton Manning, however as he hooked up with wide receiver Austin Collie for a one-yard touchdown that appeared as if it would send the game into overtime. The Jaguars got the ball back with 0:42 left on the clock, with the game tied. After a few short plays, the ball was at the Jacksonville 37-yard line with 0:33 left to play. Garrard then threw a deep pass to wide receiver Tiquan Underwood who caught it along the left sideline with 0:18 remaining in the game. Two plays later, kicker Josh Scobee lined up for a fifty-nine-yard field goal to win the game. Scobee's kick set a record for longest field goal in Jaguars franchise history.

Answer type: Number
