Task: Question Generation
Input (English): Passage: On 18 November 1763 the Mozart family arrived in Paris, one of the most important musical centres of Europe, and also a city of great power, wealth, and intellectual activity. Leopold hoped to be received by the court of Louis XV at nearby Versailles. However, a recent death in the royal family prevented any immediate invitation, so Leopold arranged other engagements. One person who took particular note of the children was the German diplomat Friedrich Melchior von Grimm, whose journal records Wolfgang's feats in glowing terms: "the most consummate Kapellmeister could not be more profound in the science of harmony and modulation". Leopold's own assessment, written a few months later, was similarly effusive: "My little girl, although only 12 years old, is one of the most skilful players in Europe and, in a word, my boy knows more in his eighth year than one would expect for a man of forty".On 24 December the family moved to Versailles for two weeks during which, through a court connection, they were able to attend a royal dinner, where Wolfgang was reportedly allowed to kiss the hand of the Queen. At Versailles they also visited the famous courtesan Madame de Pompadour, then in the last months of her life—"an extremely haughty woman who still ruled over everything", according to Leopold. In Nannerl's later recollections, Wolfgang was made to stand on a chair to be examined by the Madame, who would not allow him to kiss her.There is no record of the children giving a formal concert at Versailles. In February 1764 they were given 50 louis d'or (about 550 florins) and a gold snuff-box by the royal entertainments office, presumably for entertaining the royal family privately, but no more details are available. Further concerts were given in Paris on 10 March and on 9 April, at a private theatre in the rue et Porte St Honoré. At the same time Wolfgang's first published works were printed: two pairs of sonatas for harpsichord and violin, K. 6 and 7, and K. 8 and 9. These pairs became Opus 1 and Opus 2 in Leopold's private catalogue of his son's work. The first pair was dedicated to the king's daughter, Madame Victoire de France, the second to the Countess of Tessé. Mozart biographer Stanley Sadie comments that some aspects of these pieces are rather childish and naïve, but that nevertheless their technique is "astonishingly sure, their line of thinking is clear and smooth, and their formal balance is beyond reproach".A decision was taken in Paris to go to London, perhaps on the advice of Leopold's musical and court acquaintances, who would probably have advised him that England was, in the words of the Mozart scholar Neal Zaslaw, "known for the enthusiasm with which it received continental musicians and the extravagance with which it rewarded them". On 10 April the family left for Calais and after an unpleasant crossing to Dover on a hired boat, and some delays, arrived in London on 23 April.
Output (English): What is the full name of the person that the pair of songs known as Opus 1 by the composer's father were dedicated to?
