Problem: Several bit rates are specified in the MPEG-1 Audio Layer III standard: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320 kbit/s, with available sampling frequencies of 32, 44.1 and 48 kHz. MPEG-2 Audio Layer III allows bit rates of 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 kbit/s with sampling frequencies of 16, 22.05 and 24 kHz. MPEG-2.5 Audio Layer III is restricted to bit rates of 8, 16, 24, 32, 40, 48, 56 and 64 kbit/s with sampling frequencies of 8, 11.025, and 12 kHz.[citation needed] Because of the Nyquist–Shannon sampling theorem, frequency reproduction is always strictly less than half of the sampling frequency, and imperfect filters requires a larger margin for error (noise level versus sharpness of filter), so 8 kHz sampling rate limits the maximum frequency to 4 kHz, while 48 kHz maximum sampling rate limits an MP3 to 24 kHz sound reproduction.
What is the name of the sampling theorem?
The answer is the following: Nyquist–Shannon

Problem: Montini and Angelo Roncalli were considered to be friends, but when Roncalli, as Pope John XXIII announced a new Ecumenical Council, Cardinal Montini reacted with disbelief and said to Giulio Bevilacqua: "This old boy does not know what a hornets nest he is stirring up." He was appointed to the Central Preparatory Commission in 1961. During the Council, his friend Pope John XXIII asked him to live in the Vatican. He was a member of the Commission for Extraordinary Affairs but did not engage himself much into the floor debates on various issues. His main advisor was Monsignore Giovanni Colombo, whom he later appointed to be his successor in Milan The Commission was greatly overshadowed by the insistence of John XXIII to have the Council complete all its work in one single session before Christmas 1962, to the 400th anniversary of the Council of Trent, an insistence which may have also been influenced by the Pope's recent knowledge that he had cancer.
What illness had the Pope contracted?
The answer is the following: cancer

Problem: In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.
What is the action of the food morving down the esophagus into the stomach called?
The answer is the following: peristalsis

Problem: In the Islamic tradition, Mary and Jesus were the only children who could not be touched by Satan at the moment of their birth, for God imposed a veil between them and Satan. According to author Shabbir Akhtar, the Islamic perspective on Mary's Immaculate Conception is compatible with the Catholic doctrine of the same topic. "O People of the Book! Do not go beyond the bounds in your religion, and do not say anything of Allah but the truth. The Messiah, Jesus son of Mary, was but a Messenger of God, and a Word of His (Power) which He conveyed to Mary, and a spirit from Him. So believe in Allah (as the One, Unique God), and His Messengers (including Jesus, as Messenger); and do not say: (Allah is one of) a trinity. Give up (this assertion) â€" (it is) for your own good (to do so). Allah is but One Allah ; All-Glorified He is in that He is absolutely above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And Allah suffices as the One to be relied on, to Whom affairs should be referred." Quran 4/171
Which religion believes that God put a veil between Satan and Mary?
The answer is the following:
