Question: Within the world's Jewish population there are distinct ethnic divisions, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions. An array of Jewish communities was established by Jewish settlers in various places around the Old World, often at great distances from one another, resulting in effective and often long-term isolation. During the millennia of the Jewish diaspora the communities would develop under the influence of their local environments: political, cultural, natural, and populational. Today, manifestations of these differences among the Jews can be observed in Jewish cultural expressions of each community, including Jewish linguistic diversity, culinary preferences, liturgical practices, religious interpretations, as well as degrees and sources of genetic admixture.
Is there an answer to this question: Name another way Jewish cultural expressions differ in each community?

Answer: culinary preferences

Question: Until the 20th century, the language's spoken form was the language of only the upper noble classes and urban population, as Russian peasants from the countryside continued to speak in their own dialects. By the mid-20th century, such dialects were forced out with the introduction of the compulsory education system that was established by the Soviet government. Despite the formalization of Standard Russian, some nonstandard dialectal features (such as fricative [] in Southern Russian dialects) are still observed in colloquial speech.
Is there an answer to this question: In the mid 20th century what group was the only one that used colloquial speech?

Answer: unanswerable

Question: From early in its development, ASCII was intended to be just one of several national variants of an international character code standard, ultimately published as ISO/IEC 646 (1972), which would share most characters in common but assign other locally useful characters to several code points reserved for "national use." However, the four years that elapsed between the publication of ASCII-1963 and ISO's first acceptance of an international recommendation during 1967 caused ASCII's choices for the national use characters to seem to be de facto standards for the world, causing confusion and incompatibility once other countries did begin to make their own assignments to these code points.
Is there an answer to this question: What shared no characters in common?

Answer:
unanswerable
