Input: Read this: At all airports the use of a traffic pattern (often called a traffic circuit outside the U.S.) is possible. They may help to assure smooth traffic flow between departing and arriving aircraft. There is no technical need within modern aviation for performing this pattern, provided there is no queue. And due to the so-called SLOT-times, the overall traffic planning tend to assure landing queues are avoided. If for instance an aircraft approaches runway 17 (which has a heading of approx. 170 degrees) from the north (coming from 360/0 degrees heading towards 180 degrees), the aircraft will land as fast as possible by just turning 10 degrees and follow the glidepath, without orbit the runway for visual reasons, whenever this is possible. For smaller piston engined airplanes at smaller airfields without ILS equipment, things are very differently though.
Question: Due to this, the overall traffic planning tend to assure landing queues are avoided.

Output: so-called SLOT-times


QUES: In the early 20th century, many Europeans (particularly Spaniards and Italians but also thousands from Central Europe) immigrated to the city. In 1908, 30% of the city's population of 300,000 was foreign-born. In that decade the city expanded quickly: new neighbourhoods were created and many separate settlements were annexed to the city, among which were the Villa del Cerro, Pocitos, the Prado and Villa Colón. The Rodó Park and the Estadio Gran Parque Central were also established, which served as poles of urban development.

In 1908 what percent of the city's population was foreign-born?
What is the answer?
ANS: 30%


QUES: 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.
When were some kinds of antimicrobials first used?

ANS: over 2000 years ago


In 1807, Thomas Young was possibly the first to use the term "energy" instead of vis viva, in its modern sense. Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term "potential energy". The law of conservation of energy was also first postulated in the early 19th century, and applies to any isolated system. It was argued for some years whether heat was a physical substance, dubbed the caloric, or merely a physical quantity, such as momentum. In 1845 James Prescott Joule discovered the link between mechanical work and the generation of heat.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who discovered the link between mechanical work and the generation of heat?
Ah, so.. James Prescott Joule


Question: Between 1993 and 1996, the FBI increased its counter-terrorism role in the wake of the first 1993 World Trade Center bombing in New York City, New York; the 1995 Oklahoma City bombing in Oklahoma City, Oklahoma; and the arrest of the Unabomber in 1996. Technological innovation and the skills of FBI Laboratory analysts helped ensure that the three cases were successfully prosecuted. Justice Department investigations into the FBI's roles in the Ruby Ridge and Waco incidents were found to be obstructed by agents within the Bureau. During the 1996 Summer Olympics in Atlanta, Georgia, the FBI was criticized for its investigation of the Centennial Olympic Park bombing. It has settled a dispute with Richard Jewell, who was a private security guard at the venue, along with some media organizations, in regard to the leaking of his name during the investigation.
Try to answer this question if possible: Where was the World Trade Center?
Answer: New York City, New York


QUES: The best-known medieval Chinese name for Tibet is Tubo (Chinese: 吐蕃 also written as 土蕃 or 土番; pinyin: Tǔbō or Tǔfān). This name first appears in Chinese characters as 土番 in the 7th century (Li Tai) and as 吐蕃 in the 10th-century (Old Book of Tang describing 608–609 emissaries from Tibetan King Namri Songtsen to Emperor Yang of Sui). In the Middle Chinese spoken during that period, as reconstructed by William H. Baxter, 土番 was pronounced thux-phjon and 吐蕃 was pronounced thux-pjon (with the x representing tone).
What did Baxter H. William reconstruct?
