Problem: Since the program counter is (conceptually) just another set of memory cells, it can be changed by calculations done in the ALU. Adding 100 to the program counter would cause the next instruction to be read from a place 100 locations further down the program. Instructions that modify the program counter are often known as "jumps" and allow for loops (instructions that are repeated by the computer) and often conditional instruction execution (both examples of control flow).
Loops are defined as what?
The answer is the following: instructions that are repeated by the computer)

Problem: The Quran and Muhammad talked about racial equality and justice as in The Farewell Sermon. Tribal and nationalistic differences were discouraged. But after Muhammad's passing, the old tribal differences between the Arabs started to resurface. Following the Roman–Persian Wars and the Byzantine–Sassanid Wars, deep rooted differences between Iraq, formally under the Persian Sassanid Empire, and Syria, formally under the Byzantine Empire, also existed. Each wanted the capital of the newly established Islamic State to be in their area. Previously, the second caliph Umar was very firm on the governors and his spies kept an eye on them. If he felt that a governor or a commander was becoming attracted to wealth, he had him removed from his position.
Who controlled Iraq before the Arabs?
The answer is the following: Persian Sassanid Empire

Problem: During the early High Middle Ages, Germany was ruled by the Ottonian dynasty, which struggled to control the powerful dukes ruling over territorial duchies tracing back to the Migration period. In 1024, they were replaced by the Salian dynasty, who famously clashed with the papacy under Emperor Henry IV (r. 1084–1105) over church appointments as part of the Investiture Controversy. His successors continued to struggle against the papacy as well as the German nobility. A period of instability followed the death of Emperor Henry V (r. 1111–25), who died without heirs, until Frederick I Barbarossa (r. 1155–90) took the imperial throne. Although he ruled effectively, the basic problems remained, and his successors continued to struggle into the 13th century. Barbarossa's grandson Frederick II (r. 1220–1250), who was also heir to the throne of Sicily through his mother, clashed repeatedly with the papacy. His court was famous for its scholars and he was often accused of heresy. He and his successors faced many difficulties, including the invasion of the Mongols into Europe in the mid-13th century. Mongols first shattered the Kievan Rus' principalities and then invaded Eastern Europe in 1241, 1259, and 1287.
The clash between Henry IV and the pope was part of what greater conflict?
The answer is the following: Investiture Controversy

Problem: Melbourne is an international cultural centre, with cultural endeavours spanning major events and festivals, drama, musicals, comedy, music, art, architecture, literature, film and television. The climate, waterfront location and nightlife make it one of the most vibrant destinations in Australia. For five years in a row (as of 2015) it has held the top position in a survey by The Economist Intelligence Unit of the world's most liveable cities on the basis of a number of attributes which include its broad cultural offerings. The city celebrates a wide variety of annual cultural events and festivals of all types, including Australia's largest free community festival—Moomba, the Melbourne International Arts Festival, Melbourne International Film Festival, Melbourne International Comedy Festival and the Melbourne Fringe Festival. The culture of the city is an important drawcard for tourists, of which just under two million international overnight visitors and 57.7 million domestic overnight visited during the year ending March 2014.
What is Australia's largest free community festival?
The answer is the following:
