Question: 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?

Answer: date


Question: Passage: The "tale of two halves" sports clich&#233; was never more true to life as it was Sunday October 1 in AT&T Stadium, as the Dallas Cowboys lost to the visiting Los Angeles Rams 35-30 after dominating the first half of play. Dallas was in the driver's seat and looked ready to demolish the young Rams and their rookie head coach after a workmanlike, dominating first half that saw Dallas post three touchdowns after long-distance drives and hold a 24-16 halftime lead. The second half saw Dallas' offense virtually grind to a halt while Los Angeles slowly chipped away at the lead, finally finding themselves ahead to stay after Todd Gurley's 53-yard catch-and-run put L.A. up 26-24 late in the third quarter. After Dallas posted a 4th-quarter TD on a pass to TE James Hanna, L.A. was able to answer with its 7th field goal of the game. With the score 35-30, a late Dallas rally failed, and the Cowboys found themselves 2-2 with a looming meeting at home vs. the Green Bay Packers October 8.
Question: How many points did the Cowboys lose to the Rams?

Answer: number


Question: Passage: Following this victory, Edward realized that to create a force capable of retaking Jerusalem it would be necessary to end the internal unrest within the Christian state, and so he mediated between Hugh and his unenthusiastic knights from the Ibelin family of Cyprus.  In parallel to the mediation, Prince Edward and King Hugh began negotiating a truce with Sultan Baibars; a 10-year-10-month-and-10-day agreement was reached in May 1272, at Caesarea. Almost immediately Prince Edmund departed for England, while Edward remained to see if the treaty would hold. The following month, an attempt to assassinate Edward was made. Several versions of who sent the assassin exist. According to different versions, the assassin was sent by the emir of Ramlah or by Baibars. Some legends also say that the assassin was sent by the "Old Man of the Mountains", leader of a heretical Muslim sect. Edward killed the assassin but received a festering wound from a poisoned dagger in the process, further delaying Edward's own departure. In September 1272, Edward departed Acre for Sicily and, while recuperating on the island, he first received news of the death of his son John, and then a few months later news of the death of his father.  In 1273 Edward started his homeward journey via Italy, Gascony and Paris. Edward finally reached England in the middle of 1274, and was crowned King of England on 19 August 1274.
