Question: The official published membership statistics, such as those mentioned above, include only those who submit reports for their personal ministry; official statistics do not include inactive and disfellowshipped individuals or others who might attend their meetings. As a result, only about half of those who self-identified as Jehovah's Witnesses in independent demographic studies are considered active by the faith itself. The 2008 US Pew Forum on Religion & Public Life survey found a low retention rate among members of the religion: about 37% of people raised in the religion continued to identify themselves as Jehovah's Witnesses.
Is there an answer to this question: According to a 2008 US Pew Forum report how many Protestants identify as still active in the faith they grew up in?

Answer: unanswerable

Question: In 1629, the Massachusetts Bay Colony's first governor, John Winthrop, led the signing of the Cambridge Agreement, a key founding document of the city. Puritan ethics and their focus on education influenced its early history; America's first public school was founded in Boston in 1635. Over the next 130 years, the city participated in four French and Indian Wars, until the British defeated the French and their native allies in North America. Boston was the largest town in British North America until Philadelphia grew larger in the mid 18th century.
Is there an answer to this question: America's first public school was founded in Boston in what year?

Answer: 1635

Question: Under the direction of recording engineer C. Robert Fine, Mercury Records initiated a minimalist single microphone monaural recording technique in 1951. The first record, a Chicago Symphony Orchestra performance of Pictures at an Exhibition, conducted by Rafael Kubelik, was described as "being in the living presence of the orchestra" by The New York Times music critic. The series of records was then named Mercury Living Presence. In 1955, Mercury began three-channel stereo recordings, still based on the principle of the single microphone. The center (single) microphone was of paramount importance, with the two side mics adding depth and space. Record masters were cut directly from a three-track to two-track mixdown console, with all editing of the master tapes done on the original three-tracks. In 1961, Mercury enhanced this technique with three-microphone stereo recordings using 35 mm magnetic film instead of half-inch tape for recording. The greater thickness and width of 35 mm magnetic film prevented tape layer print-through and pre-echo and gained extended frequency range and transient response. The Mercury Living Presence recordings were remastered to CD in the 1990s by the original producer, Wilma Cozart Fine, using the same method of 3-to-2 mix directly to the master recorder.
