Problem: Sichuan:

In the middle of the 17th century, the peasant rebel leader Zhang Xianzhong (16061646) from Yan'an, Shanxi Province, nicknamed Yellow Tiger, led his peasant troop from north China to the south, and conquered Sichuan. Upon capturing it, he declared himself emperor of the Daxi Dynasty (). In response to the resistance from local elites, he massacred a large native population. As a result of the massacre as well as years of turmoil during the Ming-Qing transition, the population of Sichuan fell sharply, requiring a massive resettlement of people from the neighboring Huguang Province (modern Hubei and Hunan) and other provinces during the Qing dynasty.

Which province supplied a large amount of troops to the Sichuan resettlement, following years of turmoil during the Ming-Qing transition?

Problem: Franco-Prussian War:

The army was still equipped with the Dreyse needle gun of Battle of Koniggratz fame, which was by this time showing the age of its 25-year-old design. The rifle had a range of only 600 m (2,000 ft) and lacked the rubber breech seal that permitted aimed shots. The deficiencies of the needle gun were more than compensated for by the famous Krupp 6-pounder (3 kg) steel breech-loading cannons being issued to Prussian artillery batteries. Firing a contact-detonated shell, the Krupp gun had a longer range and a higher rate of fire than the French bronze muzzle loading cannon, which relied on faulty time fuses.

What was the Dreyse rifle's tactical range?
---
A: 600 m (2,000 ft)

Problem: Heian period:

The Fujiwara controlled the throne until the reign of Emperor Go-Sanjo (1068-1073), the first emperor not born of a Fujiwara mother since the ninth century. Go-Sanjo, determined to restore imperial control through strong personal rule, implemented reforms to curb Fujiwara influence. He also established an office to compile and validate estate records with the aim of reasserting central control. Many shoen were not properly certified, and large landholders, like the Fujiwara, felt threatened with the loss of their lands. Go-Sanjo also established the In-no-cho (ja: Office of the Cloistered Emperor), which was held by a succession of emperors who abdicated to devote themselves to behind-the-scenes governance, or insei.

Who was the last emperor born to a Fujiwara mother?

A: unanswerable
