Problem: Jehovah's Witnesses is a millenarian restorationist Christian denomination with nontrinitarian beliefs distinct from mainstream Christianity. The group claims a worldwide membership of more than 8.2 million adherents involved in evangelism, convention attendance figures of more than 15 million, and an annual Memorial attendance of more than 19.9 million. Jehovah's Witnesses are directed by the Governing Body of Jehovah's Witnesses, a group of elders in Brooklyn, New York, which establishes all doctrines based on its interpretations of the Bible. They prefer to use their own translation, the New World Translation of the Holy Scriptures, although their literature occasionally quotes and cites other translations. They believe that the destruction of the present world system at Armageddon is imminent, and that the establishment of God's kingdom over the earth is the only solution for all problems faced by humanity.

Problem: The USA PATRIOT Act increased the powers allotted to the FBI, especially in wiretapping and monitoring of Internet activity. One of the most controversial provisions of the act is the so-called sneak and peek provision, granting the FBI powers to search a house while the residents are away, and not requiring them to notify the residents for several weeks afterwards. Under the PATRIOT Act's provisions, the FBI also resumed inquiring into the library records of those who are suspected of terrorism (something it had supposedly not done since the 1970s).
What increased the powers of the FBI?
The answer is the following: USA PATRIOT Act

Problem: Various theories for the decline of the Native American populations emphasize epidemic diseases, conflicts with Europeans, and conflicts among warring tribes. Scholars now believe that, among the various contributing factors, epidemic disease was the overwhelming cause of the population decline of the American natives. Some believe that after first contacts with Europeans and Africans, Old World diseases caused the death of 90 to 95% of the native population of the New World in the following 150 years. Smallpox killed up to one third of the native population of Hispaniola in 1518. By killing the Incan ruler Huayna Capac, smallpox caused the Inca Civil War. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, measles in 1618—all ravaged the remains of Inca culture.
How long did it take for the Old World diseases to decimate the native population to the extent it did?
The answer is the following:
150 years
