Passage: Melanie Daniels, a young socialite, meets criminal defense attorney Mitch Brenner in a San Francisco pet shop. Mitch wants to purchase a pair of lovebirds for his sister's eleventh birthday, but the shop has none. He recognizes Melanie from a court appearance, but she does not know him; he plays a prank by pretending to mistake her for a saleswoman. Melanie is infuriated by the prank—but finds herself romantically intrigued by Mitch.
Melanie purchases a pair of lovebirds and drives to Mitch's weekend address in Bodega Bay to deliver them. Wanting to surprise him, she rents a motorboat so she can approach the Brenner house from the bay instead of the road. She sneaks the birds inside the house and heads back across the bay. Mitch discovers the birds, spots Melanie's boat during her retreat, and drives around the bay to meet her. Melanie is attacked and injured by a seagull near shore on the town side. Mitch treats her abrasion and invites her to dinner; she hesitantly agrees.
Melanie gets to know Mitch, his domineering mother Lydia, and his younger sister Cathy. She also befriends local school teacher Annie Hayworth, Mitch's ex-lover. While spending the night at Annie's house, she and Annie are startled by a loud thud: a gull kills itself by flying into the front door. At Cathy's birthday party the next day, the guests are attacked by seagulls. The following evening, sparrows invade the Brenner home through the chimney. 
Question: What is the first name of the person who befriends a local school teacher?

Melanie.

Passage: Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present. 
Question: Who played the keyboard with striking virtuosity?

Ex Output:
Wolfgang.

Passage: Giovanni Battista Barbirolli was born in Southampton Row, Holborn, London, the second child and eldest son of an Italian father and a French mother. He was a British national from birth, and as Southampton Row is within the sound of Bow Bells, Barbirolli always regarded himself as a Cockney. His father, Lorenzo Barbirolli (1864–1929), was a Venetian violinist who had settled in London with his wife, Louise Marie, née Ribeyrol (1870–1962). Lorenzo and his father had played in the orchestra at La Scala, Milan, where they had taken part in the première of Otello in 1887. In London they played in West End theatre orchestras, principally that of the Empire, Leicester Square.
The young Barbirolli began to play the violin when he was four, but soon changed to the cello. He later said that this was at the instigation of his grandfather who, exasperated at the child's habit of wandering around while practising the violin, bought him a small cello to stop him from "getting in everybody's way". His education at St. Clement Danes Grammar School overlapped, from 1910, with a scholarship at Trinity College of Music. As a Trinity student, he made his concert debut in a cello concerto in the Queen's Hall in 1911. The following year he won a scholarship to the Royal Academy of Music, which he attended from 1912 to 1916, studying harmony, counterpoint and theory under Dr. J. B. McEwen and the cello with Herbert Walenn. In 1914 he was joint winner of the academy's Charles Rube Prize for ensemble playing, and in 1916 The Musical Times singled him out as "that excellent young 'cello player, Mr Giovanni Barbirolli." The principal of the Academy, Sir Alexander Mackenzie, had forbidden students to play the chamber music of Ravel, which he regarded as "a pernicious influence". Barbirolli was keenly interested in modern music, and he and three colleagues secretly rehearsed Ravel's String Quartet in the privacy of a men's lavatory in the Academy.From 1916 to 1918 Barbirolli was a freelance cellist in London. He recalled, "My first orchestral engagement was with the Queen's Hall Orchestra – I was probably the youngest orchestral musician ever, joining them in 1916. We had an enormous repertory – six concerts a week, three hours or more rehearsal a day. In those days we were happy if we began and finished together". While playing in the Queen's Hall Orchestra, Barbirolli also played in the opera pit for the Beecham and Carl Rosa opera companies, in recitals with the pianist Ethel Bartlett, with orchestras in theatres, cinemas, hotels and dance-halls, and, as he said, "everywhere except the street". During the last year of the First World War, Barbirolli enlisted in the army and became a lance-corporal in the Suffolk Regiment. Here he had his first opportunity to conduct, when an orchestra of volunteers was formed. He later described the experience:.
