Problem: Another 44 million acres (18 million hectares) are owned by 12 regional, and scores of local, Native corporations created under the Alaska Native Claims Settlement Act (ANCSA) of 1971. Regional Native corporation Doyon, Limited often promotes itself as the largest private landowner in Alaska in advertisements and other communications. Provisions of ANCSA allowing the corporations' land holdings to be sold on the open market starting in 1991 were repealed before they could take effect. Effectively, the corporations hold title (including subsurface title in many cases, a privilege denied to individual Alaskans) but cannot sell the land. Individual Native allotments can be and are sold on the open market, however.
Which group claims it is Alaska's largest public land owner?

A more sophisticated MP3 encoder can produce variable bitrate audio. MPEG audio may use bitrate switching on a per-frame basis, but only layer III decoders must support it. VBR is used when the goal is to achieve a fixed level of quality. The final file size of a VBR encoding is less predictable than with constant bitrate. Average bitrate is VBR implemented as a compromise between the two: the bitrate is allowed to vary for more consistent quality, but is controlled to remain near an average value chosen by the user, for predictable file sizes. Although an MP3 decoder must support VBR to be standards compliant, historically some decoders have bugs with VBR decoding, particularly before VBR encoders became widespread.
What do encoders use when the goal is to achieve a fixed level of quality?
A: VBR

Context and question: The CIA established its first training facility, the Office of Training and Education, in 1950. Following the end of the Cold War, the CIA's training budget was slashed, which had a negative effect on employee retention. In response, Director of Central Intelligence George Tenet established CIA University in 2002. CIA University holds between 200 and 300 courses each year, training both new hires and experienced intelligence officers, as well as CIA support staff. The facility works in partnership with the National Intelligence University, and includes the Sherman Kent School for Intelligence Analysis, the Directorate of Analysis' component of the university.
How many annual courses does the CIA University have?
Answer: between 200 and 300

Question: There were also opponents to the support of any established church even at the state level. In 1773, Isaac Backus, a prominent Baptist minister in New England, wrote against a state sanctioned religion, saying: "Now who can hear Christ declare, that his kingdom is, not of this world, and yet believe that this blending of church and state together can be pleasing to him?" He also observed that when "church and state are separate, the effects are happy, and they do not at all interfere with each other: but where they have been confounded together, no tongue nor pen can fully describe the mischiefs that have ensued." Thomas Jefferson's influential Virginia Statute for Religious Freedom was enacted in 1786, five years before the Bill of Rights.
Is there an answer to this question: When did Isaac Backus write against a state sanctioned religion?

Answer: 1773

In addition there are two service bells, cast by Robert Mot, in 1585 and 1598 respectively, a Sanctus bell cast in 1738 by Richard Phelps and Thomas Lester and two unused bellsone cast about 1320, by the successor to R de Wymbish, and a second cast in 1742, by Thomas Lester. The two service bells and the 1320 bell, along with a fourth small silver "dish bell", kept in the refectory, have been noted as being of historical importance by the Church Buildings Council of the Church of England.
Where isn't the "dish bell" kept?
A:
unanswerable
