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.

In some fields Hellenistic culture thrived, particularly in its preservation of the past. The states of the Hellenistic period were deeply fixated with the past and its seemingly lost glories. The preservation of many classical and archaic works of art and literature (including the works of the three great classical tragedians, Aeschylus, Sophocles, and Euripides) are due to the efforts of the Hellenistic Greeks. The museum and library of Alexandria was the center of this conservationist activity. With the support of royal stipends, Alexandrian scholars collected, translated, copied, classified and critiqued every book they could find. Most of the great literary figures of the Hellenistic period studied at Alexandria and conducted research there. They were scholar poets, writing not only poetry but treatises on Homer and other archaic and classical Greek literature.
Who is most responsible for the preservation of Hellenistic culture?
****
The answer: Hellenistic Greeks

The innovative production techniques devised by post-punk producers such as Martin Hannett and Dennis Bovell during this period would become an important element of the emerging music, with studio experimentation taking a central role. A variety of groups that predated punk, such as Cabaret Voltaire and Throbbing Gristle, experimented with crude production techniques and electronic instruments in tandem with performance art methods and influence from transgressive literature, ultimately helping to pioneer industrial music. Throbbing Gristle's independent label Industrial Records would become a hub for this scene and provide it with its namesake.
What was the name of Throbbing Gristle's record label?
****
The answer: Industrial Records

Wood to be used for construction work is commonly known as lumber in North America. Elsewhere, lumber usually refers to felled trees, and the word for sawn planks ready for use is timber. In Medieval Europe oak was the wood of choice for all wood construction, including beams, walls, doors, and floors. Today a wider variety of woods is used: solid wood doors are often made from poplar, small-knotted pine, and Douglas fir.
What was the preferred wood for construction in Medieval Europe?
****
The answer:
oak
