Problem: 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.

Problem: On the evening of May 18, CCTV-1 hosted a special four-hour program called The Giving of Love (simplified Chinese: ; traditional Chinese: ), hosted by regulars from the CCTV New Year's Gala and round-the-clock coverage anchor Bai Yansong. It was attended by a wide range of entertainment, literary, business and political figures from mainland China, Hong Kong, Singapore and Taiwan. Donations of the evening totalled 1.5 billion Chinese Yuan (~US$208 million). Of the donations, CCTV gave the biggest corporate contribution at 50 million. Almost at the same time in Taiwan, a similarly themed programme was on air hosted by the sitting president Ma Ying-jeou. In June, Hong Kong actor Jackie Chan, who donated $1.57 million to the victims, made a music video alongside other artists entitled "Promise"; the song was composed by Andy Lau. The Artistes 512 Fund Raising Campaign, an 8-hour fundraising marathon, was held on June 1 in Hong Kong; it was attended by some 200 Sinosphere musicians and celebrities. In Singapore, MediaCorp Channel 8 hosted a 'live' programme to raise funds for the victims.

Problem: The immediate cause of the war resided in the candidacy of a Leopold of Hohenzollern-Sigmaringen, a Prussian prince, to the throne of Spain. France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern prince's candidacy was withdrawn under French diplomatic pressure, but Otto von Bismarck goaded the French into declaring war by altering a telegram sent by William I. Releasing the Ems Dispatch to the public, Bismarck made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France.
What was the name of the famous telelgram?
