question:
Passage: After their success in the Morea, the Ottomans moved against the Venetian-held Ionian Islands. They occupied the island of Lefkada , which the Venetians had taken in 1684, and the fort of Butrinto opposite the city of Corfu. On 8 July 1716, an Ottoman army of 33,000 men landed on Corfu, the most important of the Ionian islands. Despite an indecisive naval battle on the same day, the Ottoman land army continued its disembarkment and advanced towards the city of Corfu. On 19 July, after capturing the outlying forts of Mantouki, Garitsa, Avrami and of the Saviour, the siege began. The defence was led by Count Johann Matthias von der Schulenburg, who had roughly 8,000 men at his command. The extensive fortifications and the determination of the defenders withstood several assaults. After a great storm on 9 August—which the defenders attributed to the intervention of Corfu's patron saint, Saint Spyridon—caused significant casualties among the besiegers, the siege was broken off on 11 August and the last Ottoman forces withdrew on 20 August. 
Question: How many days after the siege was broken off did the Ottoman forces withdraw? 
Answer type: Number 
answer:
9.

Passage: Hoping to rebound from their loss in Kansas City, the 49ers went home for Week 5 as they played a Bay Area battle with the Oakland Raiders. The Niners drew first blood with QB Alex Smith throwing a 4-yard TD pass to WR Arnaz Battle, yet the Raiders would respond with kicker Sebastian Janikowski getting a 33-yard field goal for the first quarter. In the second quarter, things started to look grim, as Oakland took the lead with Janikowski kicking a 36-yard field goal, while QB Andrew Walter threw a 22-yard TD pass to WR Randy Moss. In the third quarter, the 49ers would rebound, as Smith hooked up with Battle again for a 6-yard TD pass. Later, Alex would throw a 33-yard TD pass to RB Maurice Hicks, giving San Francisco the lead. In the fourth quarter, the 49ers continued to roll, as kicker Joe Nedney kicked a 19-yard field goal, while rookie DE Melvin Oliver returned a fumble 12 yards for a touchdown. The Niners would allow one last touchdown from the Raiders, in the form of QB Marques Tuiasosopo completing an 8-yard pass to TE Courtney Anderson, but Nedney would help the Niners get win #2 with a 39-yard field goal. This beating of their Cross-bay rivals would bring the 49ers to a 2-3 record. 
Question: How many yards longer was Alex Smith's second touchdown pass compared to his first? 
Answer type: Number
