Problem: The stress of the war had taken its toll on the King's health, exacerbated by his heavy smoking and subsequent development of lung cancer among other ailments, including arteriosclerosis and thromboangiitis obliterans. A planned tour of Australia and New Zealand was postponed after the King suffered an arterial blockage in his right leg, which threatened the loss of the leg and was treated with a right lumbar sympathectomy in March 1949. His elder daughter Elizabeth, the heir presumptive, took on more royal duties as her father's health deteriorated. The delayed tour was re-organised, with Elizabeth and her husband, the Duke of Edinburgh, taking the place of the King and Queen. The King was well enough to open the Festival of Britain in May 1951, but on 23 September 1951, his left lung was removed by Clement Price Thomas after a malignant tumour was found. In October 1951, Princess Elizabeth and the Duke of Edinburgh went on a month-long tour of Canada; the trip had been delayed for a week due to the King's illness. At the State Opening of Parliament in November, the King's speech from the throne was read for him by the Lord Chancellor, Lord Simonds. His Christmas broadcast of 1951 was recorded in sections, and then edited together.

Hospital Vilardebo is the only psychiatric hospital in Montevideo. Named after the physician and naturalist Teodoro Vilardebo Matuliche, it opened 21 May 1880. The hospital was originally one of the best of Latin America and in 1915 grew to 1,500 inpatients. Today the hospital is very deteriorated, with broken walls and floors, lack of medicines, beds, and rooms for the personnel. It has an emergency service, outpatient, clinic and inpatient rooms and employs approximately 610 staff, psychologists, psychiatrists, social workers, administrators, guards, among others. The average patient age is 30 years; more than half of the patients arrive by court order; 42% suffer from schizophrenia, 18% from depression and mania, and there are also a high percentage of drug addicted patients.

Context and question: Chopin seldom performed publicly in Paris. In later years he generally gave a single annual concert at the Salle Pleyel, a venue that seated three hundred. He played more frequently at salons, but preferred playing at his own Paris apartment for small groups of friends. The musicologist Arthur Hedley has observed that "As a pianist Chopin was unique in acquiring a reputation of the highest order on the basis of a minimum of public appearancesfew more than thirty in the course of his lifetime." The list of musicians who took part in some of his concerts provides an indication of the richness of Parisian artistic life during this period. Examples include a concert on 23 March 1833, in which Chopin, Liszt and Hiller performed (on pianos) a concerto by J.S. Bach for three keyboards; and, on 3 March 1838, a concert in which Chopin, his pupil Adolphe Gutmann, Charles-Valentin Alkan, and Alkan's teacher Joseph Zimmermann performed Alkan's arrangement, for eight hands, of two movements from Beethoven's 7th symphony. Chopin was also involved in the composition of Liszt's Hexameron; he wrote the sixth (and final) variation on Bellini's theme. Chopin's music soon found success with publishers, and in 1833 he contracted with Maurice Schlesinger, who arranged for it to be published not only in France but, through his family connections, also in Germany and England.
Who did Chopin contract with for publishing his music?
Answer: Maurice Schlesinger

Question: In the traditional domain noted in RFC 1591, .org is for "organizations that didn't fit anywhere else" in the naming system, which implies that it is the proper category for non-commercial organizations if they are not governmental, educational, or one of the other types with a specific TLD. It is not designated specifically for charitable organizations or any specific organizational or tax-law status, however; it encompasses anything that is not classifiable as another category. Currently, no restrictions are enforced on registration of .com or .org, so one can find organizations of all sorts in either of these domains, as well as other top-level domains including newer, more specific ones which may apply to particular sorts of organizations such as .museum for museums or .coop for cooperatives. Organizations might also register by the appropriate country code top-level domain for their country.
Is there an answer to this question: What restrictions are there enforced on tld?

Answer: unanswerable

Problem: Department store:

Selfridges was established in 1909 by American-born Harry Gordon Selfridge on Oxford Street. The company's innovative marketing promoted the radical notion of shopping for pleasure rather than necessity and its techniques were adopted by modern department stores the world over. The store was extensively promoted through paid advertising. The shop floors were structured so that goods could be made more accessible to customers. There were elegant restaurants with modest prices, a library, reading and writing rooms, special reception rooms for French, German, American and "Colonial" customers, a First Aid Room, and a Silence Room, with soft lights, deep chairs, and double-glazing, all intended to keep customers in the store as long as possible. Staff members were taught to be on hand to assist customers, but not too aggressively, and to sell the merchandise. Selfridge attracted shoppers with educational and scientific exhibits; in 1909, Louis Bleriot's monoplane was exhibited at Selfridges (Bleriot was the first to fly over the English Channel), and the first public demonstration of television by John Logie Baird took place in the department store in 1925.
