Input: Read this: The ease of creating and sharing MP3s resulted in widespread copyright infringement. Major record companies argued that this free sharing of music reduced sales, and called it "music piracy". They reacted by pursuing lawsuits against Napster (which was eventually shut down and later sold) and against individual users who engaged in file sharing.
Question: What kind of infringement resulted from sharing MP3s?

Output: copyright


QUES: In November 2008, economist Dean Baker observed: "There is a really good reason for tighter credit. Tens of millions of homeowners who had substantial equity in their homes two years ago have little or nothing today. Businesses are facing the worst downturn since the Great Depression. This matters for credit decisions. A homeowner with equity in her home is very unlikely to default on a car loan or credit card debt. They will draw on this equity rather than lose their car and/or have a default placed on their credit record. On the other hand, a homeowner who has no equity is a serious default risk. In the case of businesses, their creditworthiness depends on their future profits. Profit prospects look much worse in November 2008 than they did in November 2007... While many banks are obviously at the brink, consumers and businesses would be facing a much harder time getting credit right now even if the financial system were rock solid. The problem with the economy is the loss of close to $6 trillion in housing wealth and an even larger amount of stock wealth.

What is one of the major problems with the economy in November 2008?
What is the answer?
ANS: loss of close to $6 trillion in housing wealth


QUES: Most of the Estonian Defence Forces surrendered according to the orders of the Estonian government, believing that resistance was useless and were disarmed by the Red Army. Only the Estonian Independent Signal Battalion showed resistance to Red Army and Communist militia "People's Self-Defence" units in front of the XXI Grammar School in Tallinn on 21 June. As the Red Army brought in additional reinforcements supported by six armoured fighting vehicles, the battle lasted several hours until sundown. Finally the military resistance was ended with negotiations and the Independent Signal Battalion surrendered and was disarmed. There were two dead Estonian servicemen, Aleksei Männikus and Johannes Mandre, and several wounded on the Estonian side and about ten killed and more wounded on the Soviet side.
What was the name of the single unit that didn't surrender?

ANS: the Estonian Independent Signal Battalion


Angels in the Outfield was Eisenhower's favorite movie. His favorite reading material for relaxation were the Western novels of Zane Grey. With his excellent memory and ability to focus, Eisenhower was skilled at card games. He learned poker, which he called his "favorite indoor sport," in Abilene. Eisenhower recorded West Point classmates' poker losses for payment after graduation, and later stopped playing because his opponents resented having to pay him. A classmate reported that after learning to play contract bridge at West Point, Eisenhower played the game six nights a week for five months.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was Eisenhower's favorite author?
Ah, so.. Zane Grey


Question: Utrecht is the centre of a densely populated area, which makes concise definitions of its agglomeration difficult, and somewhat arbitrary. The smaller Utrecht agglomeration of continuously built up areas counts some 420,000 inhabitants and includes Nieuwegein, IJsselstein and Maarssen. It is sometimes argued that the close by municipalities De Bilt, Zeist, Houten, Vianen, Driebergen-Rijsenburg (Utrechtse Heuvelrug), and Bunnik should also be counted towards the Utrecht agglomeration, bringing the total to 640,000 inhabitants. The larger region, including slightly more remote towns such as Woerden and Amersfoort counts up to 820,000 inhabitants.
Try to answer this question if possible: What does the dense population make difficult 
Answer: which makes concise definitions of its agglomeration difficult, and somewhat arbitrary.


Context and question: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.
What is the net quality of the ground dependent of?
Answer:
topography
