Question: The rivalries between the Arab tribes had caused unrest in the provinces outside Syria, most notably in the Second Muslim Civil War of 680692 CE and the Berber Revolt of 740743 CE. During the Second Civil War, leadership of the Umayyad clan shifted from the Sufyanid branch of the family to the Marwanid branch. As the constant campaigning exhausted the resources and manpower of the state, the Umayyads, weakened by the Third Muslim Civil War of 744747 CE, were finally toppled by the Abbasid Revolution in 750 CE/132 AH. A branch of the family fled across North Africa to Al-Andalus, where they established the Caliphate of Cordoba, which lasted until 1031 before falling due to the Fitna of al-Andalus.
Try to answer this question if possible: When did leadership shift from the Marwanid branch to the Sufyanid branch?
Answer: unanswerable
Question: Indigenous genetic studies suggest that the first inhabitants of the Americas share a single ancestral population, one that developed in isolation, conjectured to be Beringia. The isolation of these peoples in Beringia might have lasted 1020,000 years. Around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets.
Try to answer this question if possible: What do studies on the genetics of the first American inhabitants conclude about their ancestral population?
Answer: single
Question: During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first university was founded, there were twenty-nine universities spread throughout Europe. In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. It should be noted that the identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
Try to answer this question if possible: The Mediterranean Empire had how many universities?
Answer: unanswerable
Question: The greatest number of surviving Gothic buildings are churches. These range from tiny chapels to large cathedrals, and although many have been extended and altered in different styles, a large number remain either substantially intact or sympathetically restored, demonstrating the form, character and decoration of Gothic architecture. The Gothic style is most particularly associated with the great cathedrals of Northern France, the Low Countries, England and Spain, with other fine examples occurring across Europe.
Try to answer this question if possible: What is one region with which the Gothic style is distinctly connected with?
Answer:
Northern France
