Problem: According to Der Spiegel, credits given to European governments were disguised as "swaps" and consequently did not get registered as debt because Eurostat at the time ignored statistics involving financial derivatives. A German derivatives dealer had commented to Der Spiegel that "The Maastricht rules can be circumvented quite legally through swaps," and "In previous years, Italy used a similar trick to mask its true debt with the help of a different US bank." These conditions had enabled Greek as well as many other European governments to spend beyond their means, while meeting the deficit targets of the European Union and the monetary union guidelines. In May 2010, the Greek government deficit was again revised and estimated to be 13.6% which was the second highest in the world relative to GDP with Iceland in first place at 15.7% and Great Britain third with 12.6%. Public debt was forecast, according to some estimates, to hit 120% of GDP during 2010.
What were credits given to European governments disguised as?
The answer is the following: swaps

Problem: There is little consensus on the precise beginning of the Age of Enlightenment; the beginning of the 18th century (1701) or the middle of the 17th century (1650) are often used as epochs. French historians usually place the period, called the Siècle des Lumières (Century of Enlightenments), between 1715 and 1789, from the beginning of the reign of Louis XV until the French Revolution. If taken back to the mid-17th century, the Enlightenment would trace its origins to Descartes' Discourse on Method, published in 1637. In France, many cited the publication of Isaac Newton's Principia Mathematica in 1687. It is argued by several historians and philosophers that the beginning of the Enlightenment is when Descartes shifted the epistemological basis from external authority to internal certainty by his cogito ergo sum published in 1637. As to its end, most scholars use the last years of the century, often choosing the French Revolution of 1789 or the beginning of the Napoleonic Wars (1804–15) as a convenient point in time with which to date the end of the Enlightenment.
Most scholars use the beginning of the Napoleonic Wars or which other battle as a convenient date to end the Enlightenment?
The answer is the following: French Revolution

Problem: Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
What are dog teeth best suited for?
The answer is the following:
catching and tearing.
