Problem: One way to divide hunter-gatherer groups is by their return systems. James Woodburn uses the categories "immediate return" hunter-gatherers for egalitarian and "delayed return" for nonegalitarian. Immediate return foragers consume their food within a day or two after they procure it. Delayed return foragers store the surplus food (Kelly, 31).
Which group eats their acquired food in a day or two?
The answer is the following: immediate return

Problem: Before 2006, geneticists had largely attributed the ethnogenesis of most of the world's Jewish populations, including Ashkenazi Jews, to Israelite Jewish male migrants from the Middle East and "the women from each local population whom they took as wives and converted to Judaism." Thus, in 2002, in line with this model of origin, David Goldstein, now of Duke University, reported that unlike male Ashkenazi lineages, the female lineages in Ashkenazi Jewish communities "did not seem to be Middle Eastern", and that each community had its own genetic pattern and even that "in some cases the mitochondrial DNA was closely related to that of the host community." In his view this suggested "that Jewish men had arrived from the Middle East, taken wives from the host population and converted them to Judaism, after which there was no further intermarriage with non-Jews."
What year did David Goldstein report that unlike male Ashkenazi lineages, the female lineages in Ashkenazi Jewish communities did not seem to be Middle Eastern?
The answer is the following: 2002

Problem: Drinking chilled beer began with the development of artificial refrigeration and by the 1870s, was spread in those countries that concentrated on brewing pale lager. Chilling beer makes it more refreshing, though below 15.5 C the chilling starts to reduce taste awareness and reduces it significantly below 10 C (50 F). Beer served unchilledeither cool or at room temperature, reveal more of their flavours. Cask Marque, a non-profit UK beer organisation, has set a temperature standard range of 1214 C (5357 F) for cask ales to be served.
In what decade did drinking chilled pale lager become popular?
The answer is the following: the 1870s

Problem: While the number of cardinals was small from the times of the Roman Empire to the Renaissance, and frequently smaller than the number of recognized churches entitled to a cardinal priest, in the 16th century the College expanded markedly. In 1587, Pope Sixtus V sought to arrest this growth by fixing the maximum size of the College at 70, including 50 cardinal priests, about twice the historical number. This limit was respected until 1958, and the list of titular churches modified only on rare occasions, generally when a building fell into disrepair. When Pope John XXIII abolished the limit, he began to add new churches to the list, which Popes Paul VI and John Paul II continued to do. Today there are close to 150 titular churches, out of over 300 churches in Rome.
What was the maximum number allowed per Pope Sixtus V?
The answer is the following:
70
