In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Dodo Doubleday has been inexplicably reduced from first sergeant to staff sergeant and has resumed being orderly to his regimental commander Colonel Barkley.  Sergeant Ames is still a buck sergeant who hates Dodo because he advanced to outrank Ames within Dodo's first 24 hours in the army.  Dodo's former comrade in arms Charlie Cobb is also a buck sergeant.  As both Cobb and Ames are the best marksman in the regiment but constantly boast of their prowess, Colonel Barkley seeks to find an expert who can outshoot them.
Though possessing a photographic memory that enabled him to advance from private to senior non-commissioned officer in less than 24 hours, Dodo has one weakness: though his book knowledge enables him to give lectures on weapons disassembly and ballistics, he is gun shy and an incompetent marksman. After nearly shooting several of his fellow soldiers on the pistol range, with the actual target being the safest place to hide, Dodo is ordered to go into the woods to practice.  There his missed shots impress the picnicking colonel and his daughter Betty when Dodo accidentally shoots a hawk through the eye whilst in flight and after the colonel catches a fish who breaks the line and is in the process of rolling back into the water, an accidental discharge from Dodo's pistol shoots the fish through his eye.  Eager to deflate the boasting Ames and Cobb, the colonel bets a month's pay that Dodo can outshoot Ames and Cobb.
Ames and Cobb's hatred of Dodo increases when in the interests of promoting democracy in the United States Army, Betty invites Dodo to dinner at the colonel's quarters, but Ames and Cobb believe they have been invited as well. 
Question: Who is picnicking with the man that wants to find someone who can outshoot the buck sergeants?
Betty.

Passage: With the encouragement of his parents, Ravel applied for entry to France's most important musical college, the Conservatoire de Paris. In November 1889, playing music by Chopin, he passed the examination for admission to the preparatory piano class run by Eugène Anthiome. Ravel won the first prize in the Conservatoire's piano competition in 1891, but otherwise he did not stand out as a student.   Nevertheless, these years were a time of considerable advance in his development as a composer. The musicologist Arbie Orenstein writes that for Ravel the 1890s were a period "of immense growth ... from adolescence to maturity." 
In 1891 Ravel progressed to the classes of Charles-Wilfrid de Bériot, for piano, and Émile Pessard, for harmony. He made solid, unspectacular progress, with particular encouragement from Bériot but, in the words of the musical scholar Barbara L. Kelly, he "was only teachable on his own terms". His later teacher Gabriel Fauré understood this, but it was not generally acceptable to the conservative faculty of the Conservatoire of the 1890s. Ravel was expelled in 1895, having won no more prizes. His earliest works to survive in full are from these student days: Sérénade grotesque, for piano, and "Ballade de la Reine morte d'aimer", a mélodie setting a poem by Roland de Marès (both 1893).Ravel was never so assiduous a student of the piano as his colleagues such as Viñes and Cortot were. It was plain that as a pianist he would never match them, and his overriding ambition was to be a composer. From this point he concentrated on composition. His works from the period include the songs "Un grand sommeil noir" and "D'Anne jouant de l'espinette" to words by Paul Verlaine and Clément Marot, and the piano pieces Menuet antique and Habanera (for four-hands), the latter eventually incorporated into the Rapsodie espagnole. At around this time, Joseph Ravel introduced his son to Erik Satie, who was earning a living as a café pianist. Ravel was one of the first musicians – Debussy was another – who recognised Satie's originality and talent. Satie's constant experiments in musical form were an inspiration to Ravel, who counted them "of inestimable value". 
Question: What are the names of the two colleagues who it was plain that Ravel, as a pianist, would never match?
Viñes.

Passage: The search for a singer-actress to play Carmen began in the summer of 1873. Press speculation favoured Zulma Bouffar, who was perhaps the librettists' preferred choice. She had sung leading roles in many of Offenbach's operas, but she was unacceptable to Bizet and was turned down by du Locle as unsuitable. In September an approach was made to Marie Roze, well known for previous triumphs at the Opéra-Comique, the Opéra and in London. She refused the part when she learned that she would be required to die on stage. The role was then offered to Célestine Galli-Marié, who agreed to terms with du Locle after several months' negotiation. Galli-Marié, a demanding and at times tempestuous performer, would prove a staunch ally of Bizet, often supporting his resistance to demands from the management that the work should be toned down. At the time it was generally believed that she and the composer were conducting a love affair during the months of rehearsal.The leading tenor part of Don José was given to Paul Lhérie, a rising star of the Opéra-Comique who had recently appeared in works by Massenet and Delibes. He would later become a baritone, and in 1887 sang the role of Zurga in the Covent Garden premiere of Les pêcheurs de perles. Jacques Bouhy, engaged to sing Escamillo, was a young Belgian-born baritone who had already appeared in demanding roles such as Méphistophélès in Gounod's Faust and as Mozart's Figaro. Marguerite Chapuy, who sang Micaëla, was at the beginning of a short career in which she was briefly a star at London's Theatre Royal, Drury Lane; the impresario James H. Mapleson thought her "one of the most charming vocalists it has been my pleasure to know". However, she married and left the stage altogether in 1876, refusing Mapleson's considerable cash inducements to return. 
Question: What is the full name of the person who Mapleson thought to be "one of the most charming vocalists" it had ever been his pleasure to know?

Marguerite Chapuy.
