Question: Passage: Approximately 10,000 years ago, desertification forced hunter-gatherer societies south into the Sahel regions of northern Central Africa, where some groups settled and began farming as part of the Neolithic Revolution. Initial farming of white yam progressed into millet and sorghum, and before 3000 BC the domestication of African oil palm improved the groups' nutrition and allowed for expansion of the local populations. Bananas arrived in the region and added an important source of carbohydrates to the diet; they were also used in the production of alcoholic beverages.[when?] This Agricultural Revolution, combined with a "Fish-stew Revolution", in which fishing began to take place, and the use of boats, allowed for the transportation of goods. Products were often moved in ceramic pots, which are the first known examples of artistic expression from the region's inhabitants.

Answer: How long ago did farming force hunter-gatherer societies south?


Question: Passage: The centrality of the "separation" concept to the Religion Clauses of the Constitution was made explicit in Everson v. Board of Education, 330 U.S. 1 (1947), a case dealing with a New Jersey law that allowed government funds to pay for transportation of students to both public and Catholic schools. This was the first case in which the court applied the Establishment Clause to the laws of a state, having interpreted the due process clause of the Fourteenth Amendment as applying the Bill of Rights to the states as well as the federal legislature. Citing Jefferson, the court concluded that "The First Amendment has erected a wall between church and state. That wall must be kept high and impregnable. We could not approve the slightest breach."

Answer: When was the centrality of the "separation" concept to the Religion Clauses of the Constitution not made explicit?


Question: Passage: Following the 1974–75 Loans Affair, the Malcolm Fraser led Liberal-Country Party Coalition argued that the Whitlam Government was incompetent and delayed passage of the Government's money bills in the Senate, until the government would promise a new election. Whitlam refused, Fraser insisted leading to the divisive 1975 Australian constitutional crisis. The deadlock came to an end when the Whitlam government was dismissed by the Governor-General, Sir John Kerr on 11 November 1975 and Fraser was installed as caretaker Prime Minister, pending an election. Fraser won in a landslide at the resulting 1975 election.

Answer:
After what did Kerr claim that Whitlam delayed passage of money bills?
