Passage: Fresh off their divisional home win over the Bears on Sunday night, the Vikings flew to Ford Field for a Week 14 NFC North rematch with the winless Detroit Lions. Late in the first quarter, Minnesota would trail as Lions kicker Jason Hanson got a 25-yard field goal. In the second quarter, Detroit increased its lead as Hanson got a 23-yard field goal. The Vikings closed out the half with a 35-yard field goal from kicker Ryan Longwell. In the third quarter, Minnesota would take the lead as RB Chester Taylor got a 17-yard TD run. The Lions would reply with QB Daunte Culpepper (a former Viking) completing a 70-yard TD pass to wide receiver Calvin Johnson. In the fourth quarter, the Vikings regained the lead as QB Tarvaris Jackson completed an 11-yard TD pass to TE Visanthe Shiancoe. Detroit tried to rally as Hanson nailed a 39-yard field goal, yet Longwell helped Minnesota pull away with a 50-yard field goal, his fifth 50+ yarder of the season.

Passage: The Vikings came into Week 9 in desperation mode as they went against the 3-4 Cardinals, whom they lost the previous December in the desert. The Vikings came into the game wearing their purple pants and played the Cardinals in what was arguably a desperation game not only for the season, but head coach Brad Childress' job. His job had become more scrutinized after he acted alone to cut WR Randy Moss, which drew a bunch of boos and jeers at Childress. However, the action did not start until the 2nd quarter, when the Vikings drove down the field and had a 2nd and goal. Favre threw to Peterson behind the line, but Peterson dodged a few players and got into the end zone, which made the game 7-0 in the 2nd quarter. The very next play, when the Vikings kicked off, Stephens-Howling returned a kickoff 96 yards for a touchdown which tied the game. After that, the Vikings responded with kicker Ryan Longwell nailing a 21-yard field goal. They fell behind with QB Derek Anderson completing a 30-yard TD pass to WR Andre Roberts to close out the first half. This was followed by DB Michael Adams returning a Percy Harvin kickoff fumble 30 yards for a touchdown, and with kicker Jay Feely making a 22-yard field goal. The lead was closed down by Peterson as he got a 4-yard TD run, and by QB Brett Favre's 25-yard TD pass to TE Visanthe Shiancoe. In overtime the decision was made when Longwell successfully made a 35-yard field goal to give the Vikings the win, bringing their record up to 3-5 and temporarily saving their quarterback's and head coach's jobs.
Question: How many field goals were there in the second quarter?

Passage: In July 1449 Esen Tayisi of the Mongols launched a large-scale, three-pronged invasion of China with his puppet khagan Toqtaq-Buqa. He personally advanced on Datong in August. The eunuch official Wang Zhen, who dominated the Ming court, encouraged the 22-year-old Zhengtong Emperor to lead his own armies into battle against Esen. The size of Esen's army is unknown but a best guess puts it at some 20,000 men. The Ming army of about 500,000 was hastily assembled; its command was made up of 20 experienced generals and a large entourage of high-ranking civil officials, with Wang Zhen acting as field marshal. On August 3 Esen's army crushed a badly supplied Chinese army at Yanghe, just inside the Great Wall. The same day the Emperor appointed his half-brother Zhu Qiyu as regent. The next day he left Beijing for Juyong Pass. The objective was a short, sharp march west to Datong via the Xuanfu garrison, a campaign into the steppe and then a return to Beijing by a southerly route through Yuzhou. Initially the march was mired by heavy rain. At Juyong Pass the civil officials and generals wanted to halt and send the emperor back to Beijing, but their opinions were overruled by Wang Zhen. On August 16, the army came upon the corpse-strewn battlefield of Yanghe. When it reached Datong on August 18, reports from garrison commanders persuaded Wang Zhen that a campaign into the steppe would be too dangerous. The "expedition" was declared to have reached a victorious conclusion and on August 20 the army set out back toward China proper.
Question: How many days after coming upon the battlefield of Yanghe did Wang Zhen's army decide to turn back?
Answer type: Number
