[EX Q]: 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?

[EX Q]: Passage: The Browns then went home for their home finale of the season. The Ravens scored the first quarter's only points when Justin Tucker kicked a 31-yard field goal to make it 3-0. In the second quarter, the Browns took the lead when Duke Johnson Jr. ran for a 12-yard touchdown to make it 7-3. Though, the Ravens moved back into the lead when Joe Flacco ran for a 2-yard touchdown followed up by Flacco finding Benjamin Watson on a 33-yard pass to make it 10-7 and then 17-7. Zane Gonzalez got the Browns within a touchdown when he kicked a 45-yard field goal to make it 17-10 at halftime. In the third quarter, the Ravens scored the second half's only 10 points to eventually seal the game when Brandon Williams recovered a fumble for a 1-yard touchdown to make it 24-10. Tucker then hit a 43-yard field goal. The Ravens routed the Browns 27-10, sending them to their 15th consecutive loss and their 16th consecutive loss within the division. The loss ensured that the Browns would finish the season without a home victory for the first time since the 1999 season. With the loss, the Browns fell to 0-14 and became the first franchise to start 0-14 in consecutive seasons.

[EX Q]: Passage: In the Morean War, the Republic of Venice besieged Sinj in October 1684 and then again March and April 1685, but both times without success. In the 1685 attempt, the Venetian armies were aided by the local militia of the Republic of Poljica, who thereby rebelled against their nominal Ottoman suzerainty that had existed since 1513. In an effort to retaliate to Poljica, in June 1685, the Ottomans attacked Zadvarje, and in July 1686 Dolac and Srijane, but were pushed back, and suffered major casualties. With the help of the local population of Poljica as well as the Morlachs, the fortress of Sinj finally fell to the Venetian army on 30 September 1686. On 1 September 1687 the siege of Herceg Novi started, and ended with a Venetian victory on 30 September. Knin was taken after a twelve-day siege on 11 September 1688. The capture of the Knin Fortress marked the end of the successful Venetian campaign to expand their territory in inland Dalmatia, and it also determined much of the final border between Dalmatia and Bosnia and Herzegovina that stands today. The Ottomans would besiege Sinj again in the Second Morean War, but would be repelled. On 26 November 1690, Venice took Vrgorac, which opened the route towards Imotski and Mostar. In 1694 they managed to take areas north of the Republic of Ragusa, namely Citluk, Gabela, Zazablje, Trebinje, Popovo, Klobuk and Metkovic. In the final peace treaty, Venice did relinquish the areas of Popovo polje as well as Klek and Sutorina, to maintain the pre-existing demarcation near Ragusa.
Question: How many days did the siege of Herceg Novi take place, ending with a Venetian victory?
