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?

Passage: In April 1543 Suleiman launched another campaign in Hungary, bringing back Bran and other forts so that much of Hungary was under Ottoman control. As part of a Franco-Ottoman alliance , French troops were supplied to the Ottomans in Hungary: a French artillery unit was dispatched in 1543-1544 and attached to the Ottoman Army. In August 1543, the Ottoman succeeded in the Siege of Esztergom The siege would be followed by the capture of the Hungarian coronation city of Szekesfehervar in September 1543. Other cities that were captured during this campaign are Siklos and Szeged in order to better protect Buda. However, continuous delay of the push toward the west, because of the siege of these fortresses, meant that the Ottomans could not launch any new offensive against Austria. From 1548 to the end of the war, a Habsburg Spanish infantry tercio which had fought in the Schmalkaldic War, led by Maestre de campo Bernardo de Aldana, was detached in Hungary to fight against John Zapolya's supporters on behalf of Ferdinand. In fact, the Holy Roman Emperor Charles V sent Spanish troops to help his brother regularly from 1527 to 1553, a support that proved instrumental in Hungary remaining inside Christianity.
Question: What was former year that Charles V sent Spanish troops to help his brother?
answer:
date

Passage: After being higher in the postwar period, the U.S. unemployment rate fell below the rising eurozone unemployment rate in the mid-1980s and has remained significantly lower almost continuously since.

By 1980, over 65% were employed in services, between 25% and 30% in industry, and less than 5% in agriculture. Male unemployment continued to be significantly higher than those of females (at 9.8% vs. 7.5% in 2009). The unemployment among Caucasians continues being much lower than those for African-Americans (at 8.5% vs. 15.8% also in 2009).
