QUES: Families throughout Han China made ritual sacrifices of animals and food to deities, spirits, and ancestors at temples and shrines, in the belief that these items could be utilized by those in the spiritual realm. It was thought that each person had a two-part soul: the spirit-soul (hun ) which journeyed to the afterlife paradise of immortals (xian), and the body-soul (po ) which remained in its grave or tomb on earth and was only reunited with the spirit-soul through a ritual ceremony. These tombs were commonly adorned with uniquely decorated hollow clay tiles that function also as a doorjamb to the tomb. Otherwise known as tomb tiles, these artifacts feature holes in the top and bottom of the tile allowing it to pivot. Similar tiles have been found in the Chengdu area of Sichuan province in south-central China.

What function did the holes in the top and bottom of the tomb tiles enable them to do?
What is the answer?
ANS: allowing it to pivot
QUES: A lone naked human is at a physical disadvantage to other comparable apex predators in areas such as speed, bone density, weight, and physical strength. Humans also lack innate weaponry such as claws. Without crafted weapons, society, or cleverness, a lone human can easily be defeated by fit predatory animals, such as wild dogs, big cats and bears (see Man-eater). However, humans are not solitary creatures; they are social animals with highly developed social behaviors. Early humans, such as Homo erectus, have been using stone tools and weapons for well over a million years. Anatomically modern humans have been apex predators since they first evolved, and many species of carnivorous megafauna actively avoid interacting with humans; the primary environmental competitor for a human is other humans. The one subspecies of carnivorous megafauna that does interact frequently with humans in predatory roles is the domestic dog, but usually as a partner in predation especially if they hunt together. Cannibalism has occurred in various places, among various cultures, and for various reasons. At least a few people, such as the Donner party, are said to have resorted to it in desperation.

For how long have humans been using stone tools and weapons?
What is the answer?
ANS: well over a million years
QUES: An early non-Christian reference to the crucifixion of Jesus is likely to be Mara Bar-Serapion's letter to his son, written sometime after AD 73 but before the 3rd century AD. The letter includes no Christian themes and the author is presumed to be a pagan. The letter refers to the retributions that followed the unjust treatment of three wise men: Socrates, Pythagoras, and "the wise king" of the Jews. Some scholars see little doubt that the reference to the execution of the "king of the Jews" is about the crucifixion of Jesus, while others place less value in the letter, given the possible ambiguity in the reference.

When did Socrates write a letter to his son about the crucifixion?
What is the answer?
ANS:
unanswerable
