The problem: Answer a question about this article:
As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream. As of May 27, 2008, 34 lakes had formed due to earthquake debris blocking and damming rivers, and it was estimated that 28 of them were still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.
What formed behind blockages?
****
The answer: quake lakes

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.
Who came up with the term antibiosis?
****
The answer: Jean Paul Vuillemin


The problem: Answer a question about this article:
People of Ashkenazi descent constitute around 47.5% of Israeli Jews (and therefore 35–36% of Israelis). They have played a prominent role in the economy, media, and politics of Israel since its founding. During the first decades of Israel as a state, strong cultural conflict occurred between Sephardic and Ashkenazi Jews (mainly east European Ashkenazim). The roots of this conflict, which still exists to a much smaller extent in present-day Israeli society, are chiefly attributed to the concept of the "melting pot". That is to say, all Jewish immigrants who arrived in Israel were strongly encouraged to "melt down" their own particular exilic identities within the general social "pot" in order to become Israeli.
What was the conflict between Sephardic and Ashkenazi Jews attributed to?
****
The answer:
the concept of the "melting pot"
