Problem: Database:

In recent years there was a high demand for massively distributed databases with high partition tolerance but according to the CAP theorem it is impossible for a distributed system to simultaneously provide consistency, availability and partition tolerance guarantees. A distributed system can satisfy any two of these guarantees at the same time, but not all three. For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a reduced level of data consistency.

What is used to discourage eventual consistency?

Problem: Agriculture is dominated by the cultivation and sale of food crops such as cassava, peanuts, maize, sorghum, millet, sesame, and plantain. The annual real GDP growth rate is just above 3%. The importance of food crops over exported cash crops is indicated by the fact that the total production of cassava, the staple food of most Central Africans, ranges between 200,000 and 300,000 tonnes a year, while the production of cotton, the principal exported cash crop, ranges from 25,000 to 45,000 tonnes a year. Food crops are not exported in large quantities, but still constitute the principal cash crops of the country, because Central Africans derive far more income from the periodic sale of surplus food crops than from exported cash crops such as cotton or coffee.[citation needed] Much of the country is self-sufficient in food crops; however, livestock development is hindered by the presence of the tsetse fly.[citation needed]
What kind of exported cash crops dominate agriculture?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the next two years, the company established its first factory in south India in the town of Machilipatnam on the Coromandel Coast of the Bay of Bengal. The high profits reported by the company after landing in India initially prompted King James I to grant subsidiary licences to other trading companies in England.

how many years did the Merchants of London have to become profitabl when their charter was renewed by king james?
A: three consecutive years


Context and question: Static analysis techniques for software verification can be applied also in the scenario of query languages. In particular, the *Abstract interpretation framework has been extended to the field of query languages for relational databases as a way to support sound approximation techniques. The semantics of query languages can be tuned according to suitable abstractions of the concrete domain of data. The abstraction of relational database system has many interesting applications, in particular, for security purposes, such as fine grained access control, watermarking, etc.
What do query languages oppose in abstract interpretation frameworks?
Answer: unanswerable

In eastern Pennsylvania the Great Appalachian Valley, or Great Valley, was accessible by reason of a broad gateway between the end of South Mountain and the Highlands, and many Germans and Moravians settled here between the Susquehanna and Delaware Rivers forming the Pennsylvania Dutch community, some of whom even now speak a unique American dialect of German known as the "Pennsylvania German language" or "Pennsylvania Dutch." These latecomers to the New World were forced to the frontier to find cheap land. With their followers of both German, English and Scots-Irish origin, they worked their way southward and soon occupied all of the Shenandoah Valley, ceded by the Iroquois, and the upper reaches of the Great Valley tributaries of the Tennessee River, ceded by the Cherokee.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What language was created in Shenandoah Valley?
Ah, so..
unanswerable
