In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The only known recording made by Massenet is an excerpt from Sapho, "Pendant un an je fus ta femme", in which he plays a piano accompaniment for the soprano Georgette Leblanc. It was recorded in 1903, and was not intended for publication. It has been released on compact disc (2008), together with contemporary recordings by Grieg, Saint-Saëns, Debussy and others.In Massenet's later years, and in the decade after his death, many of his songs and opera extracts were recorded. Some of the performers were the original creators of the roles, such as Ernest van Dyck (Werther), Emma Calvé (Sapho), Hector Dufranne (Grisélidis), and Vanni Marcoux (Panurge). Complete French recordings of Manon and Werther, conducted by Élie Cohen, were issued in 1932 and 1933 and have been republished on CD. The critic Alan Blyth comments that they embody the original, intimate Opéra-Comique style of performing Massenet.Of Massenet's operas, the two best known, Manon and Werther, have been recorded many times, and studio or live recordings have been issued of many of the others, including Cendrillon, Le Cid, Don Quichotte, Esclarmonde, Hérodiade, Le jongleur de Notre-Dame,  Le mage, La Navarraise and Thaïs. Conductors on these discs include Sir Thomas Beecham, Richard Bonynge, Riccardo Chailly, Sir Colin Davis, Patrick Fournillier, Sir Charles Mackerras, Pierre Monteux, Sir Antonio Pappano and Michel Plasson. Among the sopranos and mezzos are Dame Janet Baker, Victoria de los Ángeles, Natalie Dessay, Renée Fleming, Angela Gheorghiu and Dame Joan Sutherland. Leading men in recordings of Massenet operas include Roberto Alagna, Gabriel Bacquier, Plácido Domingo, Thomas Hampson, Jonas Kaufmann, José van Dam, Alain Vanzo and Rolando Villazón.In addition to the operas, recordings have been issued of several orchestral works, including the ballet Le carillon, the piano concerto in E♭, the Fantaisie for cello and orchestra, and orchestral suites. Many individual mélodies by Massenet were included in mixed recitals on record during the 20th century, and more have been committed to disc since then, including, for the first time, a CD in 2012, exclusively devoted to his songs for soprano and piano.
