Problem: European Central Bank:

To qualify for participation in the auctions, banks must be able to offer proof of appropriate collateral in the form of loans to other entities. These can be the public debt of member states, but a fairly wide range of private banking securities are also accepted. The fairly stringent membership requirements for the European Union, especially with regard to sovereign debt as a percentage of each member state's gross domestic product, are designed to insure that assets offered to the bank as collateral are, at least in theory, all equally good, and all equally protected from the risk of inflation.

What must never be a part of a states Gross Domestic Product in order for them to be considered for particpation in auctions?

A: unanswerable

Problem: Frederic Chopin:

Although this period had been productive, the bad weather had such a detrimental effect on Chopin's health that Sand determined to leave the island. To avoid further customs duties, Sand sold the piano to a local French couple, the Canuts.[n 8] The group traveled first to Barcelona, then to Marseilles, where they stayed for a few months while Chopin convalesced. In May 1839 they headed for the summer to Sand's estate at Nohant, where they spent most summers until 1846. In autumn they returned to Paris, where Chopin's apartment at 5 rue Tronchet was close to Sand's rented accommodation at the rue Pigalle. He frequently visited Sand in the evenings, but both retained some independence. In 1842 he and Sand moved to the Square d'Orleans, living in adjacent buildings.

What had a negative effect on Chopin's health?

A: the bad weather

Problem: Planck constant:

Bohr also introduced the quantity , now known as the reduced Planck constant, as the quantum of angular momentum. At first, Bohr thought that this was the angular momentum of each electron in an atom: this proved incorrect and, despite developments by Sommerfeld and others, an accurate description of the electron angular momentum proved beyond the Bohr model. The correct quantization rules for electrons in which the energy reduces to the Bohr model equation in the case of the hydrogen atom were given by Heisenberg's matrix mechanics in 1925 and the Schrodinger wave equation in 1926: the reduced Planck constant remains the fundamental quantum of angular momentum. In modern terms, if J is the total angular momentum of a system with rotational invariance, and Jz the angular momentum measured along any given direction, these quantities can only take on the values

Who introduced the reduced Planck constant?

A: Bohr

Problem: Comics:

Similar to the problems of defining literature and film, no consensus has been reached on a definition of the comics medium, and attempted definitions and descriptions have fallen prey to numerous exceptions. Theorists such as Topffer, R. C. Harvey, Will Eisner, David Carrier, Alain Rey, and Lawrence Grove emphasize the combination of text and images, though there are prominent examples of pantomime comics throughout its history. Other critics, such as Thierry Groensteen and Scott McCloud, have emphasized the primacy of sequences of images. Towards the close of the 20th century, different cultures' discoveries of each other's comics traditions, the rediscovery of forgotten early comics forms, and the rise of new forms made defining comics a more complicated task.

What has been reached as far as defining comics is concerned?
