Input: Read this: Before the early 20th century, treatments for infections were based primarily on medicinal folklore. Mixtures with antimicrobial properties that were used in treatments of infections were described over 2000 years ago. Many ancient cultures, including the ancient Egyptians and ancient Greeks, used specially selected mold and plant materials and extracts to treat infections. More recent observations made in the laboratory of antibiosis between microorganisms led to the discovery of natural antibacterials produced by microorganisms. Louis Pasteur observed, "if we could intervene in the antagonism observed between some bacteria, it would offer perhaps the greatest hopes for therapeutics". The term 'antibiosis', meaning "against life", was introduced by the French bacteriologist Jean Paul Vuillemin as a descriptive name of the phenomenon exhibited by these early antibacterial drugs. Antibiosis was first described in 1877 in bacteria when Louis Pasteur and Robert Koch observed that an airborne bacillus could inhibit the growth of Bacillus anthracis. These drugs were later renamed antibiotics by Selman Waksman, an American microbiologist, in 1942. Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late 1880s. Ehrlich noted certain dyes would color human, animal, or bacterial cells, whereas others did not. He then proposed the idea that it might be possible to create chemicals that would act as a selective drug that would bind to and kill bacteria without harming the human host. After screening hundreds of dyes against various organisms, in 1907, he discovered a medicinally useful drug, the synthetic antibacterial salvarsan now called arsphenamine.
Question: What methods did people use before Robert Koch to treat infections?

QUES: In 1870, after France attacked Prussia, Prussia and its new allies in Southern Germany (among them Bavaria) were victorious in the Franco-Prussian War. It created the German Empire in 1871 as a German nation-state, effectively excluding the multi-ethnic Austrian Habsburg monarchy and Liechtenstein. Integrating the Austrians nevertheless remained a strong desire for many people of Germany and Austria, especially among the liberals, the social democrats and also the Catholics who were a minority within the Protestant Germany.
What did many people in Germany still want to do?

ANS: Integrating the Austrians


The members of the city council are each elected from single member districts within the city. The mayor and city attorney are elected directly by the voters of the entire city. The mayor, city attorney, and council members are elected to four-year terms, with a two-term limit. Elections are held on a non-partisan basis per California state law; nevertheless, most officeholders do identify themselves as either Democrats or Republicans. In 2007, registered Democrats outnumbered Republicans by about 7 to 6 in the city, and Democrats currently (as of 2015[update]) hold a 5-4 majority in the city council. The current mayor, Kevin Faulconer, is a Republican.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Were there more Democrats or Republicans in 2007?
Ah, so.. Democrats outnumbered Republicans by about 7 to 6


Question: By 1763, the war in Central Europe was essentially a stalemate. Frederick had retaken most of Silesia and Saxony but not the latter's capital, Dresden. His financial situation was not dire, but his kingdom was devastated and his army severely weakened. His manpower had dramatically decreased, and he had lost so many effective officers and generals that a new offensive was perhaps impossible. British subsidies had been stopped by the new Prime Minister Lord Bute, and the Russian Emperor had been overthrown by his wife, Catherine, who ended Russia's alliance with Prussia and withdrew from the war. Austria, however, like most participants, was facing a severe financial crisis and had to decrease the size of its army, something which greatly affected its offensive power. Indeed, after having effectively sustained a long war, its administration was in disarray. By that time, it still held Dresden, the southeastern parts of Saxony, the county of Glatz, and southern Silesia, but the prospect of victory was dim without Russian support. In 1763 a peace settlement was reached at the Treaty of Hubertusburg, ending the war in central Europe.
Try to answer this question if possible: What had happened to Frederick's extra troops from Russia?
Answer: Catherine, who ended Russia's alliance with Prussia and withdrew from the war

According to a 2012 Pew Research Center survey Christianity will remain the world's largest religion in 2050, if current trends continue.
