Problem: Hunting:

On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]

How many of the waterfowl in the US were endangered in 1934?

A: unanswerable

Problem: Pan-Germanism's origins began in the early 19th century following the Napoleonic Wars. The wars launched a new movement that was born in France itself during the French Revolution. Nationalism during the 19th century threatened the old aristocratic regimes. Many ethnic groups of Central and Eastern Europe had been divided for centuries, ruled over by the old Monarchies of the Romanovs and the Habsburgs. Germans, for the most part, had been a loose and disunited people since the Reformation when the Holy Roman Empire was shattered into a patchwork of states. The new German nationalists, mostly young reformers such as Johann Tillmann of East Prussia, sought to unite all the German-speaking and ethnic-German (Volksdeutsche) people.
Who ruled central and Eastern Europe during the 19th century?
---
Answer: Romanovs and the Habsburgs

A multilateral treaty is concluded among several countries. The agreement establishes rights and obligations between each party and every other party. Multilateral treaties are often regional.[citation needed] Treaties of "mutual guarantee" are international compacts, e.g., the Treaty of Locarno which guarantees each signatory against attack from another.

Context and question: The concept's origins can potentially be traced back further. Jewish law includes several considerations whose effects are similar to those of modern intellectual property laws, though the notion of intellectual creations as property does not seem to exist notably the principle of Hasagat Ge'vul (unfair encroachment) was used to justify limited-term publisher (but not author) copyright in the 16th century. In 500 BCE, the government of the Greek state of Sybaris offered one year's patent "to all who should discover any new refinement in luxury".
What Jewish principle justified copyright in 500 BCE?
Answer: unanswerable

Question: A comprehensive school is a state school that does not select its intake on the basis of academic achievement or aptitude. This is in contrast to the selective school system, where admission is restricted on the basis of selection criteria. The term is commonly used in relation to England and Wales, where comprehensive schools were introduced on an experimental basis in the 1940s and became more widespread from 1965. About 90% of British secondary school pupils now attend comprehensive schools. They correspond broadly to the public high school in the United States and Canada and to the German Gesamtschule.[citation needed]
Is there an answer to this question: What kind of school does not base its admissions on academic merit?

Answer: comprehensive school

The financial crisis was not widely predicted by mainstream economists except Raghuram Rajan, who instead spoke of the Great Moderation. A number of heterodox economists predicted the crisis, with varying arguments. Dirk Bezemer in his research credits (with supporting argument and estimates of timing) 12 economists with predicting the crisis: Dean Baker (US), Wynne Godley (UK), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Steve Keen (Australia), Jakob Brchner Madsen & Jens Kjaer Srensen (Denmark), Kurt Richebacher (US), Nouriel Roubini (US), Peter Schiff (US), and Robert Shiller (US). Examples of other experts who gave indications of a financial crisis have also been given. Not surprisingly, the Austrian economic school regarded the crisis as a vindication and classic example of a predictable credit-fueled bubble that could not forestall the disregarded but inevitable effect of an artificial, manufactured laxity in monetary supply, a perspective that even former Fed Chair Alan Greenspan in Congressional testimony confessed himself forced to return to.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was one of the only mainstream economist to predict the financial crisis?
Ah, so..
Raghuram Rajan
