input question: I have a test where I am given the following article, what is an answer for the question: What is the first name of the person who was a longtime support of Hitler? ? The Night of the Long Knives (German: Nacht der langen Messer ), or the Rohm Purge, also called Operation Hummingbird (German: Unternehmen Kolibri), was a purge that took place in Nazi Germany from June 30 to July 2, 1934, when Adolf Hitler, urged on by Hermann Goring and Heinrich Himmler, carried out a series of political extrajudicial executions intended to consolidate his hold on power in Germany, as well as to alleviate the concerns of the German military about the role of Ernst Rohm and the Sturmabteilung (SA), the Nazis' own mass paramilitary organization. Nazi propaganda presented the murders as a preventive measure against an alleged imminent coup by the SA under Rohm the so-called Rohm putsch. The primary instruments of Hitler's action, who carried out most of the killings, were the Schutzstaffel (SS) paramilitary force under Himmler and its Security Service (SD) under Reinhard Heydrich, and the Gestapo, the secret police, under Goring. Goring's personal police battalion also took part in the killings. Many of those killed in the purge were leaders of the SA, the best-known being Rohm himself, the SA's chief of staff and one of Hitler's longtime supporters and allies. Leading members of the leftist-leaning Strasserist faction of the Nazi Party, including its figurehead, Gregor Strasser, were also killed, as were establishment conservatives and anti-Nazis, such as former Chancellor Kurt von Schleicher and Bavarian politician Gustav Ritter von Kahr, who had suppressed Hitler's Munich Beer Hall Putsch in 1923. The murders of SA leaders were also intended to improve the image of the Hitler government with a German public that was increasingly critical of thuggish SA tactics.???

I have a test where I am given the following article, what is an answer for the question: What is the full name of the person Percival C. Keith worked for? ? The most promising but also the most challenging method of isotope separation was gaseous diffusion. Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular mass, so in a box containing a semi-permeable membrane and a mixture of two gases, the lighter molecules will pass out of the container more rapidly than the heavier molecules. The gas leaving the container is somewhat enriched in the lighter molecules, while the residual gas is somewhat depleted. The idea was that such boxes could be formed into a cascade of pumps and membranes, with each successive stage containing a slightly more enriched mixture. Research into the process was carried out at Columbia University by a group that included Harold Urey, Karl P. Cohen and John R. Dunning.In November 1942 the Military Policy Committee approved the construction of a 600-stage gaseous diffusion plant. On 14 December, M. W. Kellogg accepted an offer to construct the plant, which was codenamed K-25. A cost plus fixed fee contract was negotiated, eventually totaling $2.5 million. A separate corporate entity called Kellex was created for the project, headed by Percival C. Keith, one of Kellogg's vice presidents. The process faced formidable technical difficulties. The highly corrosive gas uranium hexafluoride had to be used, as no substitute could be found, and the motors and pumps would have to be vacuum tight and enclosed in inert gas. The biggest problem was the design of the barrier, which would have to be strong, porous and resistant to corrosion by uranium hexafluoride. The best choice for this seemed to be nickel, and Edward Adler and Edward Norris created a mesh barrier from electroplated nickel. A six-stage pilot plant was built at Columbia to test the process, but the Norris-Adler prototype proved to be too brittle. A rival barrier was developed from powdered nickel by Kellex, the Bell Telephone Laboratories and the Bakelite Corporation. In January 1944, Groves ordered the Kellex barrier into production.

Problem: Given the question: I have a test where I am given the following article, what is an answer for the question: What was the name of the palace that served as the royal residence of the Tang emperors for more than 220 years? ? Although Chang'an was the capital of the earlier Han and Jin dynasties, after subsequent destruction in warfare, it was the Sui dynasty model that comprised the Tang era capital. The roughly square dimensions of the city had six miles (10 km) of outer walls running east to west, and more than five miles (8 km) of outer walls running north to south. The royal palace, the Taiji Palace, stood north of the city's central axis. From the large Mingde Gates located mid-center of the main southern wall, a wide city avenue stretched from there all the way north to the central administrative city, behind which was the Chentian Gate of the royal palace, or Imperial City. Intersecting this were fourteen main streets running east to west, while eleven main streets ran north to south. These main intersecting roads formed 108 rectangular wards with walls and four gates each, and each ward filled with multiple city blocks. The city was made famous for this checkerboard pattern of main roads with walled and gated districts, its layout even mentioned in one of Du Fu's poems. During the Heian period, the city of Heian kyo (present-day Kyoto) of Japan like many cities was arranged in the checkerboard street grid pattern of the Tang capital and in accordance with traditional geomancy following the model of Chang'an. Of these 108 wards in Chang'an, two of them (each the size of two regular city wards) were designated as government-supervised markets, and other space reserved for temples, gardens, ponds, etc. Throughout the entire city, there were 111 Buddhist monasteries, 41 Daoist abbeys, 38 family shrines, 2 official temples, 7 churches of foreign religions, 10 city wards with provincial transmission offices, 12 major inns, and 6 graveyards. Some city wards were literally filled with open public playing fields or the backyards of lavish mansions for playing horse polo and cuju football. In 662, Emperor Gaozong moved the imperial court to the Daming Palace, which became the political center of the empire and served as the royal...
