Problem: Financial crisis of 2007%E2%80%9308:

The securitization markets supported by the shadow banking system started to close down in the spring of 2007 and nearly shut-down in the fall of 2008. More than a third of the private credit markets thus became unavailable as a source of funds. According to the Brookings Institution, the traditional banking system does not have the capital to close this gap as of June 2009: "It would take a number of years of strong profits to generate sufficient capital to support that additional lending volume." The authors also indicate that some forms of securitization are "likely to vanish forever, having been an artifact of excessively loose credit conditions."

When did the securitization markets supported by the shadow banking systems start to close down?

A: spring of 2007


Problem: Cooler climates can be found in certain parts of Southern European countries, for example within the mountain ranges of Spain and Italy. Additionally, the north coast of Spain experiences a wetter Atlantic climate.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Presbyterians distinguish themselves from other denominations by doctrine, institutional organization (or "church order") and worship; often using a "Book of Order" to regulate common practice and order. The origins of the Presbyterian churches are in Calvinism. Many branches of Presbyterianism are remnants of previous splits from larger groups. Some of the splits have been due to doctrinal controversy, while some have been caused by disagreement concerning the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith, which historically serves as an important confessional document – second only to the Bible, yet directing particularities in the standardization and translation of the Bible – in Presbyterian churches.
Which document is even more important than the Bible, serving as an important confessional document?
A: unanswerable


Context and question: Working with photographer Steven Klein, Madonna completed a 17-minute film called secretprojectrevolution. The BitTorrent company was selected by Madonna to release the film as part of a Madonna bundle. It was released on September 24, 2013, and consisted of the 17-minute film, its stills, a Vice interview, and a message from Madonna. With the film she launched the Art for Freedom initiative, which helped to promote "art and free speech as a means to address persecution and injustice across the globe". The website for the project has had over 3,000 art related submissions since its inception, with Madonna regularly monitoring and enlisting the help of other artists like David Blaine and Katy Perry as guest curators.
How many submissions does the initiative have?
Answer: over 3,000


Question: The 'OtherOS' functionality was not present in the updated PS Slim models, and the feature was subsequently removed from previous versions of the PS3 as part of the machine's firmware update version 3.21 which was released on April 1, 2010; Sony cited security concerns as the rationale. The firmware update 3.21 was mandatory for access to the PlayStation Network. The removal caused some controversy; as the update removed officially advertised features from already sold products, and gave rise to several class action lawsuits aimed at making Sony return the feature or provide compensation.
Is there an answer to this question: What reason did Sony give for taking out OtherOS?

Answer: security concerns


Problem: Railway electrification system:

In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic  so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.

Due to the inefficient generation of electricity in the US, diesel traction was twice as energy efficient in what year?
