QUES: The Arena Football League briefly had a two-game exhibition season in the early 2000s, a practice that ended in 2003 with a new television contract. Exhibition games outside of a structured season are relatively common among indoor American football leagues; because teams switch leagues frequently at that level of play, it is not uncommon to see some of the smaller leagues schedule exhibition games against teams that are from another league, about to join the league as a probational franchise, or a semi-pro outdoor team to fill holes in a schedule.
What started this practice in 2003?

ANS: unanswerable

QUES: In the early 1980s, a small but vocal segment of anthropologists and archaeologists attempted to demonstrate that contemporary groups usually identified as hunter-gatherers do not, in most cases, have a continuous history of hunting and gathering, and that in many cases their ancestors were agriculturalists and/or pastoralists[citation needed] who were pushed into marginal areas as a result of migrations, economic exploitation, and/or violent conflict (see, for example, the Kalahari Debate). The result of their effort has been the general acknowledgement that there has been complex interaction between hunter-gatherers and non-hunter-gatherers for millennia.[citation needed]
In very few cases, the ancestors of hunter-gatherers were what?

ANS: unanswerable

QUES: Codd's paper was picked up by two people at Berkeley, Eugene Wong and Michael Stonebraker. They started a project known as INGRES using funding that had already been allocated for a geographical database project and student programmers to produce code. Beginning in 1973, INGRES delivered its first test products which were generally ready for widespread use in 1979. INGRES was similar to System R in a number of ways, including the use of a "language" for data access, known as QUEL. Over time, INGRES moved to the emerging SQL standard.
Who used Codd's paper at Berkeley to improve a geographical database?

ANS:
Eugene Wong and Michael Stonebraker
