Article: The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in England around 1936. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After the war, in 1948, the USA released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in Britain work along similar lines was carried out by Geoffrey Dummer, then at the RRDE.

Question: What was Paul Eisler making when he came up with the printed circuit?
Ans: a radio set


Here is a question about this article: The permanent dissolution of clouds allows unhindered light and thermal radiation. The stability of the atmosphere above the desert prevents any convective overturning, thus making rainfall virtually non-existent. As a consequence, the weather tends to be sunny, dry and stable with a minimal risk of rainfall. Subsiding, diverging, dry air masses associated with subtropical high-pressure systems are extremely unfavorable for the development of convectional showers. The subtropical ridge is the predominate factor that explains the hot desert climate (Köppen climate classification BWh) of this vast region. The lowering of air is the strongest and the most effective over the eastern part of the Great Desert, in the Libyan Desert which is the sunniest, the driest and the most nearly rainless place on the planet rivaling the Atacama Desert, lying in Chile and Peru.
What is the answer to this question: What allows unhindered light and thermal radiation?
****
So... dissolution of clouds


The problem: Answer a question about this article:
Shōen holders had access to manpower and, as they obtained improved military technology (such as new training methods, more powerful bows, armor, horses, and superior swords) and faced worsening local conditions in the ninth century, military service became part of shōen life. Not only the shōen but also civil and religious institutions formed private guard units to protect themselves. Gradually, the provincial upper class was transformed into a new military elite based on the ideals of the bushi (warrior) or samurai (literally, one who serves).
Which class became a new military elite?
****
The answer: provincial upper class


Problem: Please answer a question about the following article about Digestion:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
In some organisms, how are these molecules absorbed?
A: these smaller substances are absorbed through the small intestine into the blood stream


Question: Read this and answer the question

The ECB's first supplementary longer-term refinancing operation (LTRO) with a six-month maturity was announced March 2008. Previously the longest tender offered was three months. It announced two 3-month and one 6-month full allotment of Long Term Refinancing Operations (LTROs). The first tender was settled 3 April, and was more than four times oversubscribed. The €25 billion auction drew bids amounting to €103.1 billion, from 177 banks. Another six-month tender was allotted on 9 July, again to the amount of €25 billion. The first 12-month LTRO in June 2009 had close to 1100 bidders.

How long was the time to maturity on an LTRO?
Answer: six-month


Similarly, movies and television often revert to standard, clichéd snatches of classical music to convey refinement or opulence: some of the most-often heard pieces in this category include Bach´s Cello Suite No. 1, Mozart's Eine kleine Nachtmusik, Vivaldi's Four Seasons, Mussorgsky's Night on Bald Mountain (as orchestrated by Rimsky-Korsakov), and Rossini's William Tell Overture.
What piece by Mozart is used as a cliche to convey refinement?
Eine kleine Nachtmusik
