Question: Which composer passed away at a younger age, George Gershwin or Léo Delibes?
Context: George Jacob Gershwin ( ; September 26, 1898 July 11, 1937) was an American composer and pianist.  Gershwin's compositions spanned both popular and classical genres, and his most popular melodies are widely known.  Among his best-known works are the orchestral compositions "Rhapsody in Blue" (1924) and "An American in Paris" (1928) as well as the opera "Porgy and Bess" (1935). Giuseppina Bozzacchi (23 November 1853 – 23 November 1870) was an Italian ballerina, noted for creating the role of Swanhilda in Léo Delibes' ballet "Coppélia" at the age of 16 while dancing for the Paris Opera Ballet. Clément Philibert Léo Delibes (] ; 21 February 1836 – 16 January 1891) was a French composer of the Romantic era (1815–1910), who specialised in ballets, operas, and other works for the stage.  His most notable works include the ballets "Coppélia" (1870) and "Sylvia" (1876), as well as the operas "Le roi l'a dit" (1873) and "Lakmé" (1883). Oscar Peterson Plays George Gershwin is a 1952 album by pianist Oscar Peterson of popular songs written by George Gershwin and Ira Gershwin.  Several tracks were included on the 1959 album "Oscar Peterson Plays the George Gershwin Songbook". Camille Erlanger (25 May 186324 April 1919) was a Parisian-born French opera composer.  He studied at the Paris Conservatory under Léo Delibes (composition), Georges Mathias (piano), as well as Émile Durand and Antoine Taubon (harmony).  In 1888 he won the Prix de Rome for his cantata "Velléda".  His most famous opera, "Le Juif polonais", was produced at the Opéra-Comique in 1900. In natural language processing, open information extraction (OIE) is the task of generating a structured, machine-readable representation of the information in text, usually in the form of triples or n-ary propositions.  A proposition can be understood as truth-bearer, a textual expression of a potential fact (e.g., "Dante wrote the Divine Comedy"), represented in an amenable structure for computers [e.g., ("Dante", "wrote", "Divine Comedy")].  An OIE extraction normally consists of a relation and a set of arguments.  For instance, ("Dante", "passed away in" "Ravenna") is a proposition formed by the relation "passed away in" and the arguments "Dante" and "Ravenna".  The first argument is usually referred as the subject while the second is considered to be the object. Oscar Peterson Plays the George Gershwin Songbook is a 1959 album by pianist Oscar Peterson of compositions written by George Gershwin.  Peterson had recorded many of the pieces for his 1952 album "Oscar Peterson Plays George Gershwin". This is list of operas and operettas written by the French composer Léo Delibes (1836–1891). Balanchine's had previously made a "pas de deux" to music from Léo Delibes' "Sylvia" in 1950; he expanded this into a divertissement in 1965.  The final version uses music from Delibes' ballets "La source" and "Sylvia" and choreography from the earlier pas de deux and divertissement. "La source (The Spring)" is a ballet in three acts/four scenes with a score composed by Léo Delibes and Ludwig Minkus (Minkus: Act I & Act III-Scene 2/Delibes: Act II & Act III-Scene 1) which was premiered in 1866 with choreography by Arthur Saint-Léon.  In 1878 in Vienna it was called "Naïla, die Quellenfee" ("Naïla, the Waternymph").
