Problem: Computer security:

Within computer systems, two of many security models capable of enforcing privilege separation are access control lists (ACLs) and capability-based security. Using ACLs to confine programs has been proven to be insecure in many situations, such as if the host computer can be tricked into indirectly allowing restricted file access, an issue known as the confused deputy problem. It has also been shown that the promise of ACLs of giving access to an object to only one person can never be guaranteed in practice. Both of these problems are resolved by capabilities. This does not mean practical flaws exist in all ACL-based systems, but only that the designers of certain utilities must take responsibility to ensure that they do not introduce flaws.[citation needed]

In 1983 fighting between Palestinian refugees and Lebanese factions reignited that nation's long-running civil war. A UN agreement brought an international force of peacekeepers to occupy Beirut and guarantee security. US Marines landed in August 1982 along with Italian and French forces. On October 23, 1983, a suicide bomber driving a truck filled with 6 tons of TNT crashed through a fence and destroyed the Marine barracks, killing 241 Marines; seconds later, a second bomber leveled a French barracks, killing 58. Subsequently the US Navy engaged in bombing of militia positions inside Lebanon. While US President Ronald Reagan was initially defiant, political pressure at home eventually forced the withdrawal of the Marines in February 1984.
How many Africans were killed in the attack?

Context and question: Anthropology and many other current fields are the intellectual results of the comparative methods developed in the earlier 19th century. Theorists in such diverse fields as anatomy, linguistics, and Ethnology, making feature-by-feature comparisons of their subject matters, were beginning to suspect that similarities between animals, languages, and folkways were the result of processes or laws unknown to them then. For them, the publication of Charles Darwin's On the Origin of Species was the epiphany of everything they had begun to suspect. Darwin himself arrived at his conclusions through comparison of species he had seen in agronomy and in the wild.
Who was begining to suspect diffrences between animals, languages and folkways?
Answer: unanswerable

Question: Jesus' death and resurrection underpin a variety of theological interpretations as to how salvation is granted to humanity. These interpretations vary widely in how much emphasis they place on the death of Jesus as compared to his words. According to the substitutionary atonement view, Jesus' death is of central importance, and Jesus willingly sacrificed himself as an act of perfect obedience as a sacrifice of love which pleased God. By contrast the moral influence theory of atonement focuses much more on the moral content of Jesus' teaching, and sees Jesus' death as a martyrdom. Since the Middle Ages there has been conflict between these two views within Western Christianity. Evangelical Protestants typically hold a substitutionary view and in particular hold to the theory of penal substitution. Liberal Protestants typically reject substitutionary atonement and hold to the moral influence theory of atonement. Both views are popular within the Roman Catholic church, with the satisfaction doctrine incorporated into the idea of penance.
Is there an answer to this question: What church is the sacrifice important to?

Answer: the Roman Catholic church

Sociologist James A. Beckford, in his 1975 study of Jehovah's Witnesses, classified the religion's organizational structure as Totalizing, characterized by an assertive leadership, specific and narrow objectives, control over competing demands on members' time and energy, and control over the quality of new members. Other characteristics of the classification include likelihood of friction with secular authorities, reluctance to co-operate with other religious organizations, a high rate of membership turnover, a low rate of doctrinal change, and strict uniformity of beliefs among members. Beckford identified the religion's chief characteristics as historicism (identifying historical events as relating to the outworking of God's purpose), absolutism (conviction that Jehovah's Witness leaders dispense absolute truth), activism (capacity to motivate members to perform missionary tasks), rationalism (conviction that Witness doctrines have a rational basis devoid of mystery), authoritarianism (rigid presentation of regulations without the opportunity for criticism) and world indifference (rejection of certain secular requirements and medical treatments).
