Problem: Israel:

Israel's diverse culture stems from the diversity of its population: Jews from diaspora communities around the world have brought their cultural and religious traditions back with them, creating a melting pot of Jewish customs and beliefs. Israel is the only country in the world where life revolves around the Hebrew calendar. Work and school holidays are determined by the Jewish holidays, and the official day of rest is Saturday, the Jewish Sabbath. Israel's substantial Arab minority has also left its imprint on Israeli culture in such spheres as architecture, music, and cuisine.

Work and school holidays are determined by what?

A: Jewish holidays


Problem: 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?

Context and question: The conventional merit-system degree is currently not as common in open education as it is in campus universities, although some open universities do already offer conventional degrees such as the Open University in the United Kingdom. Presently, many of the major open education sources offer their own form of certificate. Due to the popularity of open education, these new kind of academic certificates are gaining more respect and equal "academic value" to traditional degrees. Many open universities are working to have the ability to offer students standardized testing and traditional degrees and credentials. A culture is beginning to form around distance learning for people who are looking to social connections enjoyed on traditional campuses. For example, students may create study groups, meetups and movements such as UnCollege.
 Which University do not offer conventional degrees?
Answer: unanswerable


Question: The political reforms of Peter the Great (Пётр Вели́кий, Pyótr Velíkiy) were accompanied by a reform of the alphabet, and achieved their goal of secularization and Westernization. Blocks of specialized vocabulary were adopted from the languages of Western Europe. By 1800, a significant portion of the gentry spoke French daily, and German sometimes. Many Russian novels of the 19th century, e.g. Leo Tolstoy's (Лев Толсто́й) War and Peace, contain entire paragraphs and even pages in French with no translation given, with an assumption that educated readers would not need one.
Is there an answer to this question: Who wrote 'War and Peace'?

Answer: Leo Tolstoy

On the other hand, changes through the Phanerozoic correlate much better with the hyperbolic model (widely used in population biology, demography and macrosociology, as well as fossil biodiversity) than with exponential and logistic models. The latter models imply that changes in diversity are guided by a first-order positive feedback (more ancestors, more descendants) and/or a negative feedback arising from resource limitation. Hyperbolic model implies a second-order positive feedback. The hyperbolic pattern of the world population growth arises from a second-order positive feedback between the population size and the rate of technological growth. The hyperbolic character of biodiversity growth can be similarly accounted for by a feedback between diversity and community structure complexity. The similarity between the curves of biodiversity and human population probably comes from the fact that both are derived from the interference of the hyperbolic trend with cyclical and stochastic dynamics.
What model is widely used in Stochastic dynamics?
A:
unanswerable
