Problem: Airport:

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.

What assures smooth traffic flow between departing and arriving aircraft?

A: traffic pattern

Problem: The Greek shipping tradition recovered during Ottoman rule when a substantial merchant middle class developed, which played an important part in the Greek War of Independence. Today, Greek shipping continues to prosper to the extent that Greece has the largest merchant fleet in the world, while many more ships under Greek ownership fly flags of convenience. The most notable shipping magnate of the 20th century was Aristotle Onassis, others being Yiannis Latsis, George Livanos, and Stavros Niarchos.

Traditional English ale was made solely from fermented malt. The practice of adding hops to produce beer was introduced from the Netherlands in the early 15th century. Alehouses would each brew their own distinctive ale, but independent breweries began to appear in the late 17th century. By the end of the century almost all beer was brewed by commercial breweries.
What businesses were the dominant brewers of beer in England by the close of the 17th century?
A: commercial breweries

Context and question: Chopin's output as a composer throughout this period declined in quantity year by year. Whereas in 1841 he had written a dozen works, only six were written in 1842 and six shorter pieces in 1843. In 1844 he wrote only the Op. 58 sonata. 1845 saw the completion of three mazurkas (Op. 59). Although these works were more refined than many of his earlier compositions, Zamoyski opines that "his powers of concentration were failing and his inspiration was beset by anguish, both emotional and intellectual."
What can be said of these works compared to his work in other years even though the quantity was less?
Answer: more refined than many of his earlier compositions

Question: The Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty (c. 1050256 BC). The coinage issued by the central government mint in 119 BC remained the standard coinage of China until the Tang dynasty (618907 AD). The period saw a number of limited institutional innovations. To pay for its military campaigns and the settlement of newly conquered frontier territories, the government nationalized the private salt and iron industries in 117 BC, but these government monopolies were repealed during the Eastern Han period. Science and technology during the Han period saw significant advances, including papermaking, the nautical steering rudder, the use of negative numbers in mathematics, the raised-relief map, the hydraulic-powered armillary sphere for astronomy, and a seismometer employing an inverted pendulum.
Is there an answer to this question: A seismometer during the Han dynasty used what type of pendulum?

Answer: inverted

In May 1970, the Revolutionary Intellectuals Seminar was held to bring intellectuals in line with the revolution, while that year's Legislative Review and Amendment united secular and religious law codes, introducing sharia into the legal system. Ruling by decree, the RCC maintained the monarchy's ban on political parties, in May 1970 banned trade unions, and in 1972 outlawed workers' strikes and suspended newspapers. In September 1971, Gaddafi resigned, claiming to be dissatisfied with the pace of reform, but returned to his position within a month. In February 1973, he resigned again, once more returning the following month.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the RCC's view of political parties?
Ah, so..
Ruling by decree, the RCC maintained the monarchy's ban on political parties,
