The problem: Answer a question about this article:
Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) had been working on creating a global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendations ITU-R BT.709. In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI.
What does ITU-R stand for?
****
The answer: International Telecommunication Union's radio telecommunications sector

Problem: Please answer a question about the following article about Philosophy of space and time:
Albert Einstein proposed that the laws of physics should be based on the principle of relativity. This principle holds that the rules of physics must be the same for all observers, regardless of the frame of reference that is used, and that light propagates at the same speed in all reference frames. This theory was motivated by Maxwell's equations, which show that electromagnetic waves propagate in a vacuum at the speed of light. However, Maxwell's equations give no indication of what this speed is relative to. Prior to Einstein, it was thought that this speed was relative to a fixed medium, called the luminiferous ether. In contrast, the theory of special relativity postulates that light propagates at the speed of light in all inertial frames, and examines the implications of this postulate.
Before Einstein, speed was though to be relative to what?
A: the luminiferous ether

The macronutrients are carbohydrates, fats, protein, and water. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories (often called "Calories" and written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons.

Which nutrient generally provides around 37 kJ per gram?
Answer: fats

Problem: A German ethnicity emerged in the course of the Middle Ages, ultimately as a result of the formation of the kingdom of Germany within East Francia and later the Holy Roman Empire, beginning in the 9th century. The process was gradual and lacked any clear definition, and the use of exonyms designating "the Germans" develops only during the High Middle Ages. The title of rex teutonicum "King of the Germans" is first used in the late 11th century, by the chancery of Pope Gregory VII, to describe the future Holy Roman Emperor of the German Nation Henry IV. Natively, the term ein diutscher ("a German") is used for the people of Germany from the 12th century.
Who was given the prilavage of being called the first King of the Germans?
The answer is the following: Henry IV

The first known European explorer to reach Bermuda was Spanish sea captain Juan de Bermudez in 1503, after whom the islands are named. He claimed the apparently uninhabited islands for the Spanish Empire. Paying two visits to the archipelago, Bermudez never landed on the islands, but did create a recognisable map of the archipelago. Shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription in Portuguese Rock (previously called Spanish Rock). Subsequent Spanish or other European parties are believed to have released pigs there, which had become feral and abundant on the island by the time European settlement began. In 1609, the English Virginia Company, which had established Jamestown in Virginia (a term originally applied to all of the North American continent) two years earlier, permanently settled Bermuda in the aftermath of a hurricane, when the crew and passengers of the Sea Venture steered the ship onto the surrounding reef to prevent its sinking, then landed ashore.
In what year did the English Virginia Company settle permanently in Bermuda?
1609

Here is a question about this article: Pope Paul VI became the first pope to visit six continents, and was the most travelled pope in history to that time, earning the nickname "the Pilgrim Pope". With his travels he opened new avenues for the papacy, which were continued by his successors John Paul II and Benedict XVI. He travelled to the Holy Land in 1964, to the Eucharistic Congresses in Bombay, India and Bogota, Colombia. In 1966, however, he was twice denied permission to visit Poland for the 1,000th anniversary of the baptism of Poland. In 1967, however, fifty years after the first apparition, he visited Fatima in Portugal. He undertook a pastoral visit to Africa in 1969. On 27 November 1970 he was the target of an assassination attempt at Manila International Airport in the Philippines. He was only lightly stabbed by the would-be assassin Benjamin Mendoza y Amor Flores, who was subdued by the pope's personal bodyguard and trip organizer, Msgr. Paul Marcinkus.
What is the answer to this question: What was Paul Vi's nickname during his papacy?
****
So...
the Pilgrim Pope
