[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?
[A]: date


[Q]: Passage: The war between Russia and Sweden continued after the disaster of Poltava in 1709, though the shattered Swedish continental army could provide very little help. Russia captured Viborg  in 1710 and successfully held it against Swedish attempts to retake the town in 1711. In 1712 the first Russian campaign to capture Finland began under the  command of General Admiral Fyodor Apraksin. Apraksin gathered an army of 15,000 men at Vyborg and started the operation in late August. Swedish General Georg Henrik Lybecker chose not to face the Russians with his 7,500 men in the prepared positions close to Vyborg and instead withdrew west of Kymijoki river using scorched earth tactics. Apraksin's forces reached the river but chose not to cross it and instead withdrew back to Vyborg, likely due to problems in supply. Swedish efforts to maintain their defences were greatly hampered by the drain of manpower by the continental army and various garrisons around the Baltic Sea as well as by the plague outbreak that struck Finland and Sweden]] between 1710-1713, which devastated the land killing, amongst others, over half of the population of Helsingfors .
Question: How many more men did General Apraksin have over General Lybecker?
[A]: number
