Question: Read this and answer the question

Emperor Zhang's (r. 75–88 AD) reign came to be viewed by later Eastern Han scholars as the high point of the dynastic house. Subsequent reigns were increasingly marked by eunuch intervention in court politics and their involvement in the violent power struggles of the imperial consort clans. With the aid of the eunuch Zheng Zhong (d. 107 AD), Emperor He (r. 88–105 AD) had Empress Dowager Dou (d. 97 AD) put under house arrest and her clan stripped of power. This was in revenge for Dou's purging of the clan of his natural mother—Consort Liang—and then concealing her identity from him. After Emperor He's death, his wife Empress Deng Sui (d. 121 AD) managed state affairs as the regent empress dowager during a turbulent financial crisis and widespread Qiang rebellion that lasted from 107 to 118 AD.

Who concealed the identity of Emperor He's mother?
Answer: Empress Dowager Dou


Problem: The deliberate separation of the Luftwaffe from the rest of the military structure encouraged the emergence of a major "communications gap" between Hitler and the Luftwaffe, which other factors helped to exacerbate. For one thing, Göring's fear of Hitler led him to falsify or misrepresent what information was available in the direction of an uncritical and over-optimistic interpretation of air strength. When Göring decided against continuing Wever's original heavy bomber programme in 1937, the Reichsmarschall's own explanation was that Hitler wanted to know only how many bombers there were, not how many engines each had. In July 1939, Göring arranged a display of the Luftwaffe's most advanced equipment at Rechlin, to give the impression the air force was more prepared for a strategic air war than was actually the case.
What year did Goring display the Luftwaffe's advanced equipment?
The answer is the following: 1939


During the war years Universal did have a co-production arrangement with producer Walter Wanger and his partner, director Fritz Lang, lending the studio some amount of prestige productions.

Alfred Hitchcock was also borrowed for two films from Selznick International Pictures: Saboteur (1942) and Shadow of a Doubt (1943).
In what year was Shadow of a Doubt produced?

Input: Franco-Prussian War
The Prussian General Staff developed by Moltke proved to be extremely effective, in contrast to the traditional French school. This was in large part due to the fact that the Prussian General Staff was created to study previous Prussian operations and learn to avoid mistakes. The structure also greatly strengthened Moltke's ability to control large formations spread out over significant distances. The Chief of the General Staff, effectively the commander in chief of the Prussian army, was independent of the minister of war and answered only to the monarch. The French General Staff—along with those of every other European military—was little better than a collection of assistants for the line commanders. This disorganization hampered the French commanders' ability to exercise control of their forces.

What was key factor did the Prussian General Staff study?
Output: previous Prussian operations
