Problem: FA Cup:

Almost 60 years later, 80 year old career criminal Henry (Harry) James Burge claimed to have committed the theft, confessing to a newspaper, with the story being published in the Sunday Pictorial newspaper on 23 February 1958. He claimed to have carried out the robbery with two other men, although when discrepancies with a contemporaneous report in the Birmingham Post newspaper (the crime pre-dated written police reports) in his account of the means of entry and other items stolen, detectives decided there was no realistic possibility of a conviction and the case was closed. Burge claimed the cup had been melted down to make counterfeit half-crown coins, which matched known intelligence of the time, in which stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse, although Burge had no past history of forgery in a record of 42 previous convictions for which he had spent 42 years in prison. He had been further imprisoned in 1957 for seven years for theft from cars. Released in 1961, he died in 1964.

Problem: Marvel held its own comic book convention, Marvelcon '75, in spring 1975, and promised a Marvelcon '76. At the 1975 event, Stan Lee used a Fantastic Four panel discussion to announce that Jack Kirby, the artist co-creator of most of Marvel's signature characters, was returning to Marvel after having left in 1970 to work for rival DC Comics. In October 1976, Marvel, which already licensed reprints in different countries, including the UK, created a superhero specifically for the British market. Captain Britain debuted exclusively in the UK, and later appeared in American comics.
What was DC Comic's 1975 convention called?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After the war, Feynman declined an offer from the Institute for Advanced Study in Princeton, New Jersey, despite the presence there of such distinguished faculty members as Albert Einstein, Kurt Gödel and John von Neumann. Feynman followed Hans Bethe, instead, to Cornell University, where Feynman taught theoretical physics from 1945 to 1950. During a temporary depression following the destruction of Hiroshima by the bomb produced by the Manhattan Project, he focused on complex physics problems, not for utility, but for self-satisfaction. One of these was analyzing the physics of a twirling, nutating dish as it is moving through the air. His work during this period, which used equations of rotation to express various spinning speeds, proved important to his Nobel Prize–winning work, yet because he felt burned out and had turned his attention to less immediately practical problems, he was surprised by the offers of professorships from other renowned universities.
What did Feynman's work make him hated for?
A: unanswerable


Context and question: The European Central Bank had stepped up the buying of member nations debt. In response to the crisis of 2010, some proposals have surfaced for a collective European bond issue that would allow the central bank to purchase a European version of US Treasury bills. To make European sovereign debt assets more similar to a US Treasury, a collective guarantee of the member states' solvency would be necessary.[b] But the German government has resisted this proposal, and other analyses indicate that "the sickness of the euro" is due to the linkage between sovereign debt and failing national banking systems. If the European central bank were to deal directly with failing banking systems sovereign debt would not look as leveraged relative to national income in the financially weaker member states.
Which country has supported attempts to make the sovereign debt assets more like the U.S. Treasury?
Answer: unanswerable


Question: For example, consider electron–positron annihilation, in which the rest mass of individual particles is destroyed, but the inertia equivalent of the system of the two particles (its invariant mass) remains (since all energy is associated with mass), and this inertia and invariant mass is carried off by photons which individually are massless, but as a system retain their mass. This is a reversible process – the inverse process is called pair creation – in which the rest mass of particles is created from energy of two (or more) annihilating photons. In this system the matter (electrons and positrons) is destroyed and changed to non-matter energy (the photons). However, the total system mass and energy do not change during this interaction.
Is there an answer to this question: What is the inverse process called?

Answer: pair creation


QUES: Bacteria can be grown in the laboratory on nutrient culture media, but viruses need living cells in which to replicate. Many vaccines to infectious diseases can be grown in fertilised chicken eggs. Millions of eggs are used each year to generate the annual flu vaccine requirements, a complex process that takes about six months after the decision is made as to what strains of virus to include in the new vaccine. A problem with using eggs for this purpose is that people with egg allergies are unable to be immunised, but this disadvantage may be overcome as new techniques for cell-based rather than egg-based culture become available. Cell-based culture will also be useful in a pandemic when it may be difficult to acquire a sufficiently large quantity of suitable sterile, fertile eggs.
