Problem: Some writers claim the Air Staff ignored a critical lesson, however: British morale did not break. Targeting German morale, as Bomber Command would do, was no more successful. Aviation strategists dispute that morale was ever a major consideration for Bomber Command. Throughout 193339 none of the 16 Western Air Plans drafted mentioned morale as a target. The first three directives in 1940 did not mention civilian populations or morale in any way. Morale was not mentioned until the ninth wartime directive on 21 September 1940. The 10th directive in October 1940 mentioned morale by name. However, industrial cities were only to be targeted if weather denied strikes on Bomber Command's main concern, oil.
What was the critical lesson Air Staff ignored?
The answer is the following: Targeting German morale, as Bomber Command would do, was no more successful.

Problem: Two chains of DNA twist around each other to form a DNA double helix with the phosphate-sugar backbone spiralling around the outside, and the bases pointing inwards with adenine base pairing to thymine and guanine to cytosine. The specificity of base pairing occurs because adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds. The two strands in a double helix must therefore be complementary, with their sequence of bases matching such that the adenines of one strand are paired with the thymines of the other strand, and so on.:4.1
What is the backbone of a DNA double helix made of?
The answer is the following: phosphate-sugar

Problem: The increased consumption of reading materials of all sorts was one of the key features of the "social" Enlightenment. Developments in the Industrial Revolution allowed consumer goods to be produced in greater quantities at lower prices, encouraging the spread of books, pamphlets, newspapers and journals "media of the transmission of ideas and attitudes". Commercial development likewise increased the demand for information, along with rising populations and increased urbanisation. However, demand for reading material extended outside of the realm of the commercial, and outside the realm of the upper and middle classes, as evidenced by the Bibliotheque Bleue. Literacy rates are difficult to gauge, but in France at least, the rates doubled over the course of the 18th century. Reflecting the decreasing influence of religion, the number of books about science and art published in Paris doubled from 1720 to 1780, while the number of books about religion dropped to just one-tenth of the total.
In additional to rising populations and increased urbanisation, what else did Commercial development increase the need for?
The answer is the following: demand for information

Problem: Life with My Sister Madonna, a book by Madonna's brother Christopher, debuted at number two on The New York Times bestseller list. The book caused some friction between Madonna and her brother, because of the unsolicited publication. Problems also arose between Madonna and Ritchie, with the media reporting that they were on the verge of separation. Ultimately, Madonna filed for divorce from Ritchie, citing irreconcilable differences, which was finalized in December 2008. She decided to adopt from Malawi. The country's High Court initially approved the adoption of Chifundo "Mercy" James; however, the application was rejected because Madonna was not a resident of the country. Madonna appealed, and on June 12, 2009, the Supreme Court of Malawi granted Madonna the right to adopt Mercy James. She also released Celebration, her third greatest-hits album and final release with Warner. It contained the new songs "Celebration" and "Revolver" along with 34 hits spanning her career. Celebration reached number one in the UK, tying her with Elvis Presley as the solo act with most number one albums in the British chart history. She appeared at the 2009 MTV Video Music Awards on September 13, 2009, to speak in tribute to deceased pop star Michael Jackson.
When was the divorce finalized between Madonna and Ritchie?
The answer is the following:
December 2008
