Problem: The Blitz:

From 7 September 1940, one year into the war, London was bombed by the Luftwaffe for 57 consecutive nights. More than one million London houses were destroyed or damaged and more than 40,000 civilians were killed, almost half of them in London. Ports and industrial centres outside London were also attacked. The main Atlantic sea port of Liverpool was bombed, causing nearly 4,000 deaths within the Merseyside area during the war. The North Sea port of Hull, a convenient and easily found target or secondary target for bombers unable to locate their primary targets, was subjected to 86 raids in the Hull Blitz during the war, with a conservative estimate of 1,200 civilians killed and 95 percent of its housing stock destroyed or damaged. Other ports including Bristol, Cardiff, Portsmouth, Plymouth, Southampton and Swansea were also bombed, as were the industrial cities of Birmingham, Belfast, Coventry, Glasgow, Manchester and Sheffield. Birmingham and Coventry were chosen because of the Spitfire and tank factories in Birmingham and the many munitions factories in Coventry. The city centre of Coventry was almost destroyed, as was Coventry Cathedral.

Sanskrit, as defined by Pāṇini, evolved out of the earlier Vedic form. The present form of Vedic Sanskrit can be traced back to as early as the second millennium BCE (for Rig-vedic). Scholars often distinguish Vedic Sanskrit and Classical or "Pāṇinian" Sanskrit as separate dialects. Though they are quite similar, they differ in a number of essential points of phonology, vocabulary, grammar and syntax. Vedic Sanskrit is the language of the Vedas, a large collection of hymns, incantations (Samhitas) and theological and religio-philosophical discussions in the Brahmanas and Upanishads. Modern linguists consider the metrical hymns of the Rigveda Samhita to be the earliest, composed by many authors over several centuries of oral tradition. The end of the Vedic period is marked by the composition of the Upanishads, which form the concluding part of the traditional Vedic corpus; however, the early Sutras are Vedic, too, both in language and content.
What are often considered the same dialects?
A: unanswerable

Question: Early during the Taiping Rebellion, Qing forces suffered a series of disastrous defeats culminating in the loss of the regional capital city of Nanjing in 1853. Shortly thereafter, a Taiping expeditionary force penetrated as far north as the suburbs of Tianjin, the imperial heartlands. In desperation the Qing court ordered a Chinese official, Zeng Guofan, to organize regional and village militias into an emergency army called tuanlian. Zeng Guofan's strategy was to rely on local gentry to raise a new type of military organization from those provinces that the Taiping rebels directly threatened. This new force became known as the Xiang Army, named after the Hunan region where it was raised. The Xiang Army was a hybrid of local militia and a standing army. It was given professional training, but was paid for out of regional coffers and funds its commanders — mostly members of the Chinese gentry — could muster. The Xiang Army and its successor, the Huai Army, created by Zeng Guofan's colleague and mentee Li Hongzhang, were collectively called the "Yong Ying" (Brave Camp).
Is there an answer to this question: What city did the Qing lose in 1853?

Answer: Nanjing

Greek Cypriots and Turkish Cypriots share a lot in common in their culture but also have differences. Several traditional food (such as souvla and halloumi) and beverages are similar, as well as expressions and ways of life. Hospitality and buying or offering food and drinks for guests or others are common among both. In both communities, music, dance and art are integral parts of social life and many artistic, verbal and nonverbal expressions, traditional dances such as tsifteteli, similarities in dance costumes and importance placed on social activities are shared between the communities. However, the two communities have distinct religions and religious cultures, with the Greek Cypriots traditionally being Greek Orthodox and Turkish Cypriots traditionally being Sunni Muslims, which has partly hindered cultural exchange. Greek Cypriots have influences from Greece and Christianity, while Turkish Cypriots have influences from Turkey and Islam.
Which art forms are integral parts of everyday life?
A:
music, dance and art
