Article: The U.S. Federal Reserve and central banks around the world have taken steps to expand money supplies to avoid the risk of a deflationary spiral, in which lower wages and higher unemployment lead to a self-reinforcing decline in global consumption. In addition, governments have enacted large fiscal stimulus packages, by borrowing and spending to offset the reduction in private sector demand caused by the crisis. The U.S. Federal Reserve's new and expanded liquidity facilities were intended to enable the central bank to fulfill its traditional lender-of-last-resort role during the crisis while mitigating stigma, broadening the set of institutions with access to liquidity, and increasing the flexibility with which institutions could tap such liquidity.

Question: What type decline does lower wages and higher unemployment lead to?
Ans: self-reinforcing decline


Article: Much of mandolin development revolved around the soundboard (the top). Pre-mandolin instruments were quiet instruments, strung with as many as six courses of gut strings, and were plucked with the fingers or with a quill. However, modern instruments are louder—using four courses of metal strings, which exert more pressure than the gut strings. The modern soundboard is designed to withstand the pressure of metal strings that would break earlier instruments. The soundboard comes in many shapes—but generally round or teardrop-shaped, sometimes with scrolls or other projections. There is usually one or more sound holes in the soundboard, either round, oval, or shaped like a calligraphic F (f-hole). A round or oval sound hole may be covered or bordered with decorative rosettes or purfling.

Question: What are the sound holes covered with? 
Ans: bordered with decorative rosettes or purfling


Article: 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.

Question: Who was threatened by Nationalism?
Ans: aristocratic regimes
