Problem: Another source of loanwords was Old Norse, which came into contact with Old English via the Scandinavian rulers and settlers in the Danelaw from the late 9th century, and during the rule of Cnut and other Danish kings in the early 11th century. Many place-names in eastern and northern England are of Scandinavian origin. Norse borrowings are relatively rare in Old English literature, being mostly terms relating to government and administration. The literary standard, however, was based on the West Saxon dialect, away from the main area of Scandinavian influence; the impact of Norse may have been greater in the eastern and northern dialects. Certainly in Middle English texts, which are more often based on eastern dialects, a strong Norse influence becomes apparent. Modern English contains a great many, often everyday, words that were borrowed from Old Norse, and the grammatical simplification that occurred after the Old English period is also often attributed to Norse influence.
During what century did Cnut rule?

Answer: 11th

The aircraft carrier dramatically changed naval combat in World War II, because air power was becoming a significant factor in warfare. The advent of aircraft as focal weapons was driven by the superior range, flexibility and effectiveness of carrier-launched aircraft. They had higher range and precision than naval guns, making them highly effective. The versatility of the carrier was demonstrated in November 1940 when HMS Illustrious launched a long-range strike on the Italian fleet at their base in Taranto, signalling the beginning of the effective and highly mobile aircraft strikes. This operation incapacitated three of the six battleships at a cost of two torpedo bombers. World War II in the Pacific Ocean involved clashes between aircraft carrier fleets. The 1941 Japanese surprise attack on Pearl Harbor was a clear illustration of the power projection capability afforded by a large force of modern carriers. Concentrating six carriers in a single unit turned naval history about, as no other nation had fielded anything comparable. However, the vulnerability of carriers compared to traditional battleships when forced into a gun-range encounter was quickly illustrated by the sinking of HMS Glorious by German battleships during the Norwegian campaign in 1940.
Why were carrier-launched aircraft more effective than naval guns?
A: They had higher range and precision

Context and question: The CBSE (Central Board of Secondary Education) of India, along with several other state education boards, has made Sanskrit an alternative option to the state's own official language as a second or third language choice in the schools it governs. In such schools, learning Sanskrit is an option for grades 5 to 8 (Classes V to VIII). This is true of most schools affiliated with the ICSE board, especially in those states where the official language is Hindi. Sanskrit is also taught in traditional gurukulas throughout India.
What language is the state official language of India?
Answer: unanswerable

Question: Some early male settlers married Indigenous American women and had informal unions with them. Early contact between Indigenous Americans and Europeans was often charged with tension, but also had moments of friendship, cooperation, and intimacy. Marriages took place in both English and Latin colonies between European men and Native women. For instance, on April 5, 1614, Pocahontas, a Powhatan woman in present-day Virginia, married the Englishman John Rolfe of Jamestown. Their son Thomas Rolfe was an ancestor to many descendants in First Families of Virginia. As a result, English laws did not exclude people with some Indigenous American ancestry from being considered English or white.
Is there an answer to this question: What did English laws not exclude people with some native blood from being?

Answer: considered English or white
