It has been in contact with many other civilisations and nations and has been through so many eras, starting from prehistoric age to the modern age, passing through so many ages such as; Pharonic, Roman, Greek, Islamic and many other ages. Because of this wide variation of ages, the continuous contact with other nations and the big number of conflicts Egypt had been through, at least 60 museums may be found in Egypt, mainly covering a wide area of these ages and conflicts.

What is the oldest era in Egypt?

A: prehistoric


Problem: Muslim rule started in parts of north India in the 13th century when the Delhi Sultanate was founded in 1206 CE by the Central Asian Turks. The Delhi Sultanate ruled the major part of northern India in the early 14th century, but declined in the late 14th century when several powerful Hindu states such as the Vijayanagara Empire, Gajapati Kingdom, Ahom Kingdom, as well as Rajput dynasties and states, such as Mewar dynasty, emerged. The 15th century saw the emergence of Sikhism. In the 16th century, Mughals came from Central Asia and gradually covered most of India. The Mughal Empire suffered a gradual decline in the early 18th century, which provided opportunities for the Maratha Empire, Sikh Empire and Mysore Kingdom to exercise control over large areas of the subcontinent.
What group founded the Delhi Sultanate in the 13th century?
---
Answer: Central Asian Turks

The basic MP3 decoding and encoding technology is patent-free in the European Union, all patents having expired there. In the United States, the technology will be substantially patent-free on 31 December 2017 (see below). The majority of MP3 patents expired in the US between 2007 and 2015.
Where is the basic MP3 decoding and technology patent free?
A: European Union


Context and question: Caesar became consul in 59 BC. His colleague, Marcus Calpurnius Bibulus, was an extreme aristocrat. Caesar submitted the laws that he had promised Pompey to the assemblies. Bibulus attempted to obstruct the enactment of these laws, and so Caesar used violent means to ensure their passage. Caesar was then made governor of three provinces. He facilitated the election of the former patrician Publius Clodius Pulcher to the tribunate for 58 BC. Clodius set about depriving Caesar's senatorial enemies of two of their more obstinate leaders in Cato and Cicero. Clodius was a bitter opponent of Cicero because Cicero had testified against him in a sacrilege case. Clodius attempted to try Cicero for executing citizens without a trial during the Catiline conspiracy, resulting in Cicero going into self-imposed exile and his house in Rome being burnt down. Clodius also passed a bill that forced Cato to lead the invasion of Cyprus which would keep him away from Rome for some years. Clodius also passed a law to expand the previous partial grain subsidy to a fully free grain dole for citizens.
Who enacted a law that would increase the partial grain subsidy?
Answer: Clodius


Question: In 1348, the Black Death and other disasters sealed a sudden end to the previous period of massive philosophic and scientific development. Yet, the rediscovery of ancient texts was improved after the Fall of Constantinople in 1453, when many Byzantine scholars had to seek refuge in the West. Meanwhile, the introduction of printing was to have great effect on European society. The facilitated dissemination of the printed word democratized learning and allowed a faster propagation of new ideas. New ideas also helped to influence the development of European science at this point: not least the introduction of Algebra. These developments paved the way for the Scientific Revolution, which may also be understood as a resumption of the process of scientific inquiry, halted at the start of the Black Death.
Is there an answer to this question: What year did the Black Death occur?

Answer: 1348


Question: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Is there an answer to this question: How high is the continent of Antarctica above sea level?

Answer:
3,000 m
