The problem: Answer a question about this article:
In military affairs, the use of infantry with specialised roles increased. Along with the still-dominant heavy cavalry, armies often included mounted and infantry crossbowmen, as well as sappers and engineers. Crossbows, which had been known in Late Antiquity, increased in use partly because of the increase in siege warfare in the 10th and 11th centuries.[AB] The increasing use of crossbows during the 12th and 13th centuries led to the use of closed-face helmets, heavy body armour, as well as horse armour. Gunpowder was known in Europe by the mid-13th century with a recorded use in European warfare by the English against the Scots in 1304, although it was merely used as an explosive and not as a weapon. Cannon were being used for sieges in the 1320s, and hand-held guns were in use by the 1360s.
In what decade were siege cannon known to have been used?
****
The answer: 1320s

Problem: Li Zicheng then led a coalition of rebel forces numbering 200,000[a] to confront Wu Sangui, the general commanding the Ming garrison at Shanhai Pass. Shanhai Pass is a pivotal pass of the Great Wall, located fifty miles northeast of Beijing, and for years its defenses kept the Manchus from directly raiding the Ming capital. Wu Sangui, caught between a rebel army twice his size and a foreign enemy he had fought for years, decided to cast his lot with the Manchus, with whom he was familiar. Wu Sangui may have been influenced by Li Zicheng's mistreatment of his family and other wealthy and cultured officials; it was said that Li also took Wu's concubine Chen Yuanyuan for himself. Wu and Dorgon allied in the name of avenging the death of the Chongzhen Emperor. Together, the two former enemies met and defeated Li Zicheng's rebel forces in battle on May 27, 1644.
What was the name of the general at the Ming fort?
The answer is the following: Wu Sangui

Here is a question about this article: In 1816, the United Kingdom annexed the islands, ruling them from the Cape Colony in South Africa.

The occupation also prevented the United States from using Tristan da Cunha as a cruiser base, as it had during the War of 1812.
What is the answer to this question: where did the UK rule the islands from?
****
So...
South Africa
