Problem: Renewable energy commercialization:

Total investment in renewable energy (including small hydro-electric projects) was $244 billion in 2012, down 12% from 2011 mainly due to dramatically lower solar prices and weakened US and EU markets.

The top countries for investment in recent years were China, Germany, Spain, the United States, Italy, and Brazil. Renewable energy companies include BrightSource Energy, First Solar, Gamesa, GE Energy, Goldwind, Sinovel, Trina Solar, Vestas and Yingli.

Problem: At the 1966 "Man the Hunter" conference, anthropologists Richard Borshay Lee and Irven DeVore suggested that egalitarianism was one of several central characteristics of nomadic hunting and gathering societies because mobility requires minimization of material possessions throughout a population. Therefore, no surplus of resources can be accumulated by any single member. Other characteristics Lee and DeVore proposed were flux in territorial boundaries as well as in demographic composition.

Some theories suggest that the Greek word cheir (χειρ) for hand includes the wrist and that the Romans were generally trained to place nails through Destot's space (between the capitate and lunate bones) without fracturing any bones. Another theory suggests that the Greek word for hand also includes the forearm and that the nails were placed near the radius and ulna of the forearm. Ropes may have also been used to fasten the hands in addition to the use of nails.
The Romans tried to affix by avoiding what?

Context and question: The 7th and 6th centuries BC witnessed the composition of the earliest Upanishads. Upanishads form the theoretical basis of classical Hinduism and are known as Vedanta (conclusion of the Vedas). The older Upanishads launched attacks of increasing intensity on the ritual. Anyone who worships a divinity other than the Self is called a domestic animal of the gods in the Brihadaranyaka Upanishad. The Mundaka launches the most scathing attack on the ritual by comparing those who value sacrifice with an unsafe boat that is endlessly overtaken by old age and death.
What worship system is central to Hinduism?
Answer: Self


Question: The United States No Electronic Theft Act (NET Act), a federal law passed in 1997, in response to LaMacchia, provides for criminal prosecution of individuals who engage in copyright infringement under certain circumstances, even when there is no monetary profit or commercial benefit from the infringement. Maximum penalties can be five years in prison and up to $250,000 in fines. The NET Act also raised statutory damages by 50%. The court's ruling explicitly drew attention to the shortcomings of current law that allowed people to facilitate mass copyright infringement while being immune to prosecution under the Copyright Act.
Is there an answer to this question: What federal law did the United States pass in 1999, in response to the LaMacchia Loophole?

Answer: unanswerable
