Q: 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 

A: 9.

Q: Passage: Coming off a two-game winning streak, the Dolphins stayed at home for a Week 11 fight against teammate Daunte Culpepper's former team, the Minnesota Vikings.  In the first quarter, the Vikings struck first as RB Chester Taylor got a 1-yard TD run for the only score of the period.  In the second quarter, the Dolphins took to the water as kicker Olindo Mare nailed a 44-yard field goal, while QB Joey Harrington got an 11-yard TD pass to TE Justin Peelle.  In the third quarter, Minnesota came closer with kicker Ryan Longwell nailing a 35-yard field goal for the only score of the period.  In the fourth quarter, the Vikings took a three-point lead, as Longwell kicked a 19-yard field goal.  However, Miami wouldn't have any of that, as the defense stepped up and made decisive plays.  Free Safety Renaldo Hill returned a fumble 48 yards for a touchdown, while DE Jason Taylor returned an interception 51 yards for a touchdown.  Minnesota would get one more touchdown (another 1-yard TD run by Taylor), but Miami ran out the clock to preserve their 3rd victory in a row.  With the victory, the Dolphins improved to 4-6.  The Dolphins' rushing yardage was a franchise low (&#8722;3 yards), and a team record for the Vikings' defense. 
Question: How many more yards was the second TD than the first? 
Answer type: Number 

A: 10.
