Problem: The papacy further refined the practice in the Mass in the Late Middle Ages, holding that the clergy alone was allowed to partake of the wine in the Eucharist. This further distanced the secular laity from the clergy. The laity continued the practices of pilgrimages, veneration of relics, and belief in the power of the Devil. Mystics such as Meister Eckhart (d. 1327) and Thomas à Kempis (d. 1471) wrote works that taught the laity to focus on their inner spiritual life, which laid the groundwork for the Protestant Reformation. Besides mysticism, belief in witches and witchcraft became widespread, and by the late 15th century the Church had begun to lend credence to populist fears of witchcraft with its condemnation of witches in 1484 and the publication in 1486 of the Malleus Maleficarum, the most popular handbook for witch-hunters.
In what year did the Church condemn witches?
The answer is the following: 1484

Problem: 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."
How must the wall separating church and state be kept?
The answer is the following: high and impregnable

Problem: Population testing is still being done. Some Native American groups that have been sampled may not have shared the pattern of markers being searched for. Geneticists acknowledge that DNA testing cannot yet distinguish among members of differing cultural Native American nations. There is genetic evidence for three major migrations into North America, but not for more recent historic differentiation. In addition, not all Native Americans have been tested, so scientists do not know for sure that Native Americans have only the genetic markers they have identified.
What are geneticists looking for?
The answer is the following: the pattern of markers

Problem: Batman's Treaty with the Aborigines was annulled by the New South Wales governor (who at the time governed all of eastern mainland Australia), with compensation paid to members of the association. In 1836, Governor Bourke declared the city the administrative capital of the Port Phillip District of New South Wales, and commissioned the first plan for the city, the Hoddle Grid, in 1837. The settlement was named Batmania after Batman. However, later that year the settlement was named "Melbourne" after the British Prime Minister, William Lamb, 2nd Viscount Melbourne, whose seat was Melbourne Hall in the market town of Melbourne, Derbyshire. On 13 April 1837 the settlement's general post office officially opened with that name.
On what date did the official general post office open?
The answer is the following:
13 April 1837
