Ehrlich’s approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk. This work, also based in the testing of compounds available from the German dye industry, led to the development of Prontosil, the first representative of the sulfonamide class of antibiotics. Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci. In 1939, Domagk received the Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II.
Many deaths occurred before World War II due to what?
infectious diseases


Input: Franco-Prussian War
On 1 September 1870, the battle opened with the Army of Châlons, with 202 infantry battalions, 80 cavalry squadrons and 564 guns, attacking the surrounding Prussian Third and Meuse Armies totaling 222 infantry battalions, 186 cavalry squadrons and 774 guns. General De Wimpffen, the commander of the French V Corps in reserve, hoped to launch a combined infantry and cavalry attack against the Prussian XI Corps. But by 11:00, Prussian artillery took a toll on the French while more Prussian troops arrived on the battlefield. The French cavalry, commanded by General Marguerite, launched three desperate attacks on the nearby village of Floing where the Prussian XI Corps was concentrated. Marguerite was killed leading the very first charge and the two additional charges led to nothing but heavy losses. By the end of the day, with no hope of breaking out, Napoleon III called off the attacks. The French lost over 17,000 men, killed or wounded, with 21,000 captured. The Prussians reported their losses at 2,320 killed, 5,980 wounded and 700 captured or missing. By the next day, on 2 September, Napoleon III surrendered and was taken prisoner with 104,000 of his soldiers. It was an overwhelming victory for the Prussians, for they not only captured an entire French army, but the leader of France as well. The defeat of the French at Sedan had decided the war in Prussia's favour. One French army was now immobilised and besieged in the city of Metz, and no other forces stood on French ground to prevent a German invasion. Nevertheless, the war would continue.

On which date did the battle begin with the Army of Chalons attacking various Prussian divisions?
Output: 1 September 1870


Input: Article: Although Chinese characters in Vietnam are now limited to ceremonial uses, they were once in widespread use. Until the early 20th century, Literary Chinese was used in Vietnam for all official and scholarly writing. Around the 13th century the Nôm script was developed to record folk literature in the Vietnamese language. The script used Chinese characters to represent both borrowed Sino-Vietnamese vocabulary and native words with similar pronunciation or meaning. In addition thousands of new compound characters were created to write Vietnamese words. This process resulted in a highly complex system that was never mastered by more than 5% of the population. Both Literary Chinese and Nôm were replaced in the early 20th century by Vietnamese written with the Latin-based Vietnamese alphabet.

Now answer this question: What is now limited to ceremonial uses?

Output: Chinese characters in Vietnam


Article: In addition to professional team sports, North Carolina has a strong affiliation with NASCAR and stock-car racing, with Charlotte Motor Speedway in Concord hosting two Sprint Cup Series races every year. Charlotte also hosts the NASCAR Hall of Fame, while Concord is the home of several top-flight racing teams, including Hendrick Motorsports, Roush Fenway Racing, Richard Petty Motorsports, Stewart-Haas Racing, and Chip Ganassi Racing. Numerous other tracks around North Carolina host races from low-tier NASCAR circuits as well.

Question: What North Carolina city hosts the NASCAR Hall of Fame?
Ans: Charlotte


Here is a question about this article: The university culture developed differently in northern Europe than it did in the south, although the northern (primarily Germany, France and Great Britain) and southern universities (primarily Italy) did have many elements in common. Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics; while Hippocrates, Galen, and Avicenna were used for medicine. Outside of these commonalities, great differences separated north and south, primarily in subject matter. Italian universities focused on law and medicine, while the northern universities focused on the arts and theology. There were distinct differences in the quality of instruction in these areas which were congruent with their focus, so scholars would travel north or south based on their interests and means. There was also a difference in the types of degrees awarded at these universities. English, French and German universities usually awarded bachelor's degrees, with the exception of degrees in theology, for which the doctorate was more common. Italian universities awarded primarily doctorates. The distinction can be attributed to the intent of the degree holder after graduation – in the north the focus tended to be on acquiring teaching positions, while in the south students often went on to professional positions. The structure of northern universities tended to be modeled after the system of faculty governance developed at the University of Paris. Southern universities tended to be patterned after the student-controlled model begun at the University of Bologna. Among the southern universities, a further distinction has been noted between those of northern Italy, which followed the pattern of Bologna as a "self-regulating, independent corporation of scholars" and those of southern Italy and Iberia, which were "founded by royal and imperial charter to serve the needs of government."
What is the answer to this question: What type of subjects did the universities of northern Europe focus on?
****
So... arts and theology


Article: Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic. In June 1848, Paris workers, disenchanted with the new government, built barricades and raised red flags. The new government called in the French Army to put down the uprising, the first of many such confrontations between the army and the new worker's movements in Europe.

Question: Who wrote the Communist Manifesto?
Ans:
Karl Marx
