Problem: Jews:

Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.

Problem: Notable Greek seafarers include people such as Pytheas of Marseilles, Scylax of Caryanda who sailed to Iberia and beyond, Nearchus, the 6th century merchant and later monk Cosmas Indicopleustes (Cosmas who sailed to India) and the explorer of the Northwestern passage Juan de Fuca. In later times, the Romioi plied the sea-lanes of the Mediterranean and controlled trade until an embargo imposed by the Roman Emperor on trade with the Caliphate opened the door for the later Italian pre-eminence in trade.
What did Greeks do that caused a later deal to be made with the Italians ?

Answer: plied the sea-lanes of the Mediterranean and controlled trade

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically closest to Amerindians.[citation needed] This view is shared by other researchers who argue that "the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic. 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis. The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%; xQ1a 4-32%).
What group were the ancestors of the American Indians separated from?
A: Asian population

Question: The term "matter" is used throughout physics in a bewildering variety of contexts: for example, one refers to "condensed matter physics", "elementary matter", "partonic" matter, "dark" matter, "anti"-matter, "strange" matter, and "nuclear" matter. In discussions of matter and antimatter, normal matter has been referred to by Alfven as koinomatter (Gk. common matter). It is fair to say that in physics, there is no broad consensus as to a general definition of matter, and the term "matter" usually is used in conjunction with a specifying modifier.
Is there an answer to this question: Matter usually does not need to be used in conjunction with what?

Answer: unanswerable

Question: Following this battle, Ali fought a battle against Muawiyah, known as the Battle of Siffin. The battle was stopped before either side had achieved victory, and the two parties agreed to arbitrate their dispute. After the battle Amr ibn al-As was appointed by Muawiyah as an arbitrator, and Ali appointed Abu Musa Ashaari. Seven months later, in February 658, the two arbitrators met at Adhruh, about 10 miles north west of Maan in Jordon. Amr ibn al-As convinced Abu Musa Ashaari that both Ali and Muawiyah should step down and a new Caliph be elected. Ali and his supporters were stunned by the decision which had lowered the Caliph to the status of the rebellious Muawiyah I. Ali was therefore outwitted by Muawiyah and Amr. Ali refused to accept the verdict and found himself technically in breach of his pledge to abide by the arbitration. This put Ali in a weak position even amongst his own supporters. The most vociferous opponents in Ali's camp were the very same people who had forced Ali into the ceasefire. They broke away from Ali's force, rallying under the slogan, "arbitration belongs to God alone." This group came to be known as the Kharijites ("those who leave"). In 659 Ali's forces and the Kharijites met in the Battle of Nahrawan. Although Ali won the battle, the constant conflict had begun to affect his standing, and in the following years some Syrians seem to have acclaimed Muawiyah as a rival caliph.
