QUES: In 2007, the Institute for Policy Innovation (IPI) reported that music piracy took $12.5 billion from the U.S. economy. According to the study, musicians and those involved in the recording industry are not the only ones who experience losses attributed to music piracy. Retailers have lost over a billion dollars, while piracy has resulted in 46,000 fewer production-level jobs and almost 25,000 retail jobs. The U.S. government was also reported to suffer from music piracy, losing $422 million in tax revenue.

Who reported that piracy gained $12.5 billion for the U.S. economy?

QUES: While exploring inland along the northern coast of Florida in 1528, the members of the Narvaez expedition, including Alvar Nunez Cabeza de Vaca, found a Native American village near present-day Tallahassee, Florida whose name they transcribed as Apalchen or Apalachen [a.pala.tn]. The name was soon altered by the Spanish to Apalachee and used as a name for the tribe and region spreading well inland to the north. Panfilo de Narvaez's expedition first entered Apalachee territory on June 15, 1528, and applied the name. Now spelled "Appalachian," it is the fourth-oldest surviving European place-name in the US.
When did the Narvaez expedition explore Florida?

ANS: 1528

DDT, sprayed on the walls of houses, is an organochlorine that has been used to fight malaria since the 1950s. Recent policy statements by the World Health Organization have given stronger support to this approach. However, DDT and other organochlorine pesticides have been banned in most countries worldwide because of their persistence in the environment and human toxicity. DDT use is not always effective, as resistance to DDT was identified in Africa as early as 1955, and by 1972 nineteen species of mosquito worldwide were resistant to DDT.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long has DDT been banned worldwide?
Ah, so.. unanswerable
