In 2013 the United States Patent & Trademark Office approximated that the worth of intellectual property to the U.S. economy is more than US$5 trillion and creates employment for an estimated 18 million American people. The value of intellectual property is considered similarly high in other developed nations, such as those in the European Union. In the UK, IP has become a recognised asset class for use in pension-led funding and other types of business finance. However, in 2013, the UK Intellectual Property Office stated: "There are millions of intangible business assets whose value is either not being leveraged at all, or only being leveraged inadvertently".

How many Americans did intellectual property create employment for in 2013?
Answer: 18 million


Problem: In 2003, Nintendo announced that a new The Legend of Zelda game was in the works for the GameCube by the same team that had created the cel-shaded The Wind Waker. At the following year's Game Developers Conference, director Eiji Aonuma unintentionally revealed that the game's sequel was in development under the working title The Wind Waker 2; it was set to use a similar graphical style to that of its predecessor. Nintendo of America told Aonuma that North American sales of The Wind Waker were sluggish because its cartoon appearance created the impression that the game was designed for a young audience. Concerned that the sequel would have the same problem, Aonuma expressed to producer Shigeru Miyamoto that he wanted to create a realistic Zelda game that would appeal to the North American market. Miyamoto, hesitant about solely changing the game's presentation, suggested the team's focus should instead be on coming up with gameplay innovations. He advised that Aonuma should start by doing what could not be done in Ocarina of Time, particularly horseback combat.[l]
Who was the director that unintentionally announced a Zelda game was in the works?
The answer is the following: Eiji Aonuma


Until recently, in the absence of prior agreement on a clear and precise definition, the concept was thought to mean (as a shorthand) 'a division of sovereignty between two levels of government'. New research, however, argues that this cannot be correct, as dividing sovereignty - when this concept is properly understood in its core meaning of the final and absolute source of political authority in a political community - is not possible. The descent of the United States into Civil War in the mid-nineteenth century, over disputes about unallocated competences concerning slavery and ultimately the right of secession, showed this. One or other level of government could be sovereign to decide such matters, but not both simultaneously. Therefore, it is now suggested that federalism is more appropriately conceived as 'a division of the powers flowing from sovereignty between two levels of government'. What differentiates the concept from other multi-level political forms is the characteristic of equality of standing between the two levels of government established. This clarified definition opens the way to identifying two distinct federal forms, where before only one was known, based upon whether sovereignty resides in the whole (in one people) or in the parts (in many peoples): the federal state (or federation) and the federal union of states (or federal union), respectively. Leading examples of the federal state include the United States, Germany, Canada, Switzerland, Australia and India. The leading example of the federal union of states is the European Union.
What is the difference between multi-level political forms and federalism? 
the characteristic of equality of standing between the two levels of government established
