Native Sumerian rule re-emerged for about a century in the Neo-Sumerian Empire or Third Dynasty of Ur (Sumerian Renaissance) approximately 2100-2000 BC, but the Akkadian language also remained in use. The Sumerian city of Eridu, on the coast of the Persian Gulf, is considered to have been the world's first city, where three separate cultures may have fused that of peasant Ubaidian farmers, living in mud-brick huts and practicing irrigation; that of mobile nomadic Semitic pastoralists living in black tents and following herds of sheep and goats; and that of fisher folk, living in reed huts in the marshlands, who may have been the ancestors of the Sumerians.
How many cultures may have fused together in Eridu?

The answer: three

From September 1823 to 1826 Chopin attended the Warsaw Lyceum, where he received organ lessons from the Czech musician Wilhelm Wurfel during his first year. In the autumn of 1826 he began a three-year course under the Silesian composer Jozef Elsner at the Warsaw Conservatory, studying music theory, figured bass and composition.[n 3] Throughout this period he continued to compose and to give recitals in concerts and salons in Warsaw. He was engaged by the inventors of a mechanical organ, the "eolomelodicon", and on this instrument in May 1825 he performed his own improvisation and part of a concerto by Moscheles. The success of this concert led to an invitation to give a similar recital on the instrument before Tsar Alexander I, who was visiting Warsaw; the Tsar presented him with a diamond ring. At a subsequent eolomelodicon concert on 10 June 1825, Chopin performed his Rondo Op. 1. This was the first of his works to be commercially published and earned him his first mention in the foreign press, when the Leipzig Allgemeine Musikalische Zeitung praised his "wealth of musical ideas".
Who gave Chopin instruction on how to play the organ?

The answer: Wilhelm Wurfel

The problem: Answer a question about this article:
French cooperation was deemed necessary to the campaign, and Eisenhower encountered a "preposterous situation" with the multiple rival factions in France. His primary objective was to move forces successfully into Tunisia, and intending to facilitate that objective, he gave his support to Francois Darlan as High Commissioner in North Africa, despite Darlan's previous high offices of state in Vichy France and his continued role as commander-in-chief of the French armed forces. The Allied leaders were "thunderstruck" by this from a political standpoint, though none of them had offered Eisenhower guidance with the problem in the course of planning the operation. Eisenhower was severely criticized for the move. Darlan was assassinated on December 24 by Fernand Bonnier de La Chapelle. Eisenhower did not take action to prevent the arrest and extrajudicial execution of Bonnier de La Chapelle by associates of Darlan acting without authority from either Vichy or the Allies, considering it a criminal rather than a military matter. Eisenhower later appointed General Henri Giraud as High Commissioner, who had been installed by the Allies as Darlan's commander-in-chief, and who had refused to postpone the execution.
What geographic area was the primary objective of Eisenhower?
****
The answer: Tunisia

Mosaic has a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman kingdom in Sicily in the 12th century, by eastern-influenced Venice, and among the Rus in Ukraine. Mosaic fell out of fashion in the Renaissance, though artists like Raphael continued to practise the old technique. Roman and Byzantine influence led Jews to decorate 5th and 6th century synagogues in the Middle East with floor mosaics.
The Norman kingdomwas in what italian city state?
****
The answer:
Sicily
