PROBLEM: 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: When was the Zhengtong Emperor born?

SOLUTION: date

PROBLEM: Passage: Coming off their divisional home win over the Jaguars, the Titans flew to Candlestick Park for a Week 9 interconference duel with the San Francisco 49ers. Tennessee would trail early in the first quarter as 49ers kicker Joe Nedney got a 40-yard field goal, yet the Titans would answer with kicker Rob Bironas making a 21-yard field goal. The Titans would take the lead in the second quarter as quarterback Vince Young got a 10-yard touchdown run, but San Francisco would close out the half with a 3-yard touchdown run from running back Frank Gore and a 12-yard touchdown pass from quarterback Alex Smith to wide receiver Jason Hill. In the third quarter, Tennessee would tie the game as running back Chris Johnson got a 1-yard touchdown. The 49ers would retake their lead in the fourth quarter with Nedney nailing a 25-yard field goal, yet the Titans would regain the lead with Johnson's 2-yard touchdown run, Bironas' 28-yard field goal, and cornerback Cortland Finnegan's 39-yard interception return for a touchdown. San Francisco tried to make a comeback as Smith found Hill again on a 3-yard touchdown pass, yet Tennessee's defense held up for the victory.
