Question: Overture in G major was written by the composer who worked for most of his life in which country?

Context paragraphs:
Symphony No. 4 (Mahler): Symphony No. 4 in G major by Gustav Mahler was written in 1899 and 1900, though it incorporates a song originally written in 1892.  The song, "Das himmlische Leben", presents a child's vision of Heaven.  It is sung by a soprano in the work's fourth and last movement.  Although typically described as being in the key of G major, the symphony employs a progressive tonal scheme ('(b)/G—E').

Symphony No. 3 (Michael Haydn): Michael Haydn's Symphony No. 3 in G major, also known as Divertimento in G major, Sherman 3, MH 26, was written in Großwardein in 1763, according to the Göttweig catalog.  It is not listed in the Perger catalog.  Wolfgang Amadeus Mozart's Salzburg Symphonies are examples of symphonies that were also called divertimenti (Guy, 1999)

Overture in G major (Cherubini): The Overture in G major by Luigi Cherubini (1760-1842) is an orchestral work written for concert use in early 1815.  It is unusual among Cherubini's overtures in that his other, better known overtures (such as those to "Anacreon", "Médée", "Les deux journées" and "Ali Baba"), were intended to introduce stage works.  Although born in Italy Cherubini had been living in France since 1784, and had earned world fame through a series of operas composed for the Paris stage.  In the first decade of the nineteenth century the vogue for his dramatic works began to wane, and he turned increasingly to sacred music.

Luigi Cherubini: Luigi Cherubini (] ; 8 or 14 September 1760 – 15 March 1842) was an Italian composer who spent most of his working life in France.  His most significant compositions are operas and sacred music.  Beethoven regarded Cherubini as the greatest of his contemporaries.

Overture in the French style, BWV 831: The Overture in the French style, BWV 831, original title Ouvertüre nach Französischer Art, also known as the French Overture and published as the second half of Clavier-Übung II in 1735 (paired with the "Italian Concerto"), is a suite in B minor for two-manual harpsichord written by Johann Sebastian Bach.  An earlier version of this work exists, in the key of C minor (BWV 831a); the work was transposed into B minor to complete the cycle of tonalities in Parts One and Two of the Clavier-Übung.  The keys of the six Partitas (B♭ major, C minor, A minor, D major, G major, E minor) form a sequence of intervals going up and then down by increasing amounts: a second up (B♭ to C), a third down (C to A), a fourth up (A to D), a fifth down (D to G), and finally a sixth up (G to E).  The key sequence continues into "Clavier-Übung II" (1735) with two larger works: the Italian Concerto, a seventh down (E to F), and the French Overture, an augmented fourth up (F to B♮ ).  Thus this sequence of customary tonalities for 18th-century keyboard compositions is complete, extending from the first letter of his name (Bach's "home" key, B♭ , in German is B) to the last letter of his name (B♮ in German is H).

Twenty Variations in G major (Haydn): Twenty Variations in G major, Hob.  XVII/2, was written in the 1760s by Joseph Haydn.  In 1788/1789, Artaria published the "Arietta con 12 Variazioni in A major" (Twelve Variations in A major), which is an abridged version of the Twenty Variations in G major, and in a different key.

Parallel key: In music, a major scale and a minor scale that have the same tonic are called parallel keys and are said to be in a parallel relationship.  The parallel minor or tonic minor of a particular major key is the minor key based on the same tonic; similarly the parallel major has the same tonic as the minor key (from the Greek, "para alleilos", "beside each other").  For example, G major and G minor have different modes but both have the same tonic, G; so we say that G minor is the parallel minor of G major.  In contrast, a major scale and a minor scale that have the same key signature (and therefore different tonics) are called relative keys.

Symphony No. 35 (Michael Haydn): Michael Haydn's Symphony No. 35 in G major, Perger 27, Sherman 35, MH 474, written in Salzburg in 1788, is the last G major symphony he wrote, the second of his final set of six symphonies.

In G Major: In G Major is a ballet made for New York City Ballet's Ravel Festival by ballet master Jerome Robbins to the composer's "Piano Concerto in G Major" (1928–31).  The premiere took place May 15, 1975 at the New York State Theater, Lincoln Center, with lighting by Mark Stanley.  The Paris Opera Ballet commissioned scenery and costumes by Erté when it staged Robbins' ballet under the name "En Sol", decor which has subsequently been borrowed by City Ballet.  Ravel composed the concerto after travelling in the United States and is reported to have described the work as "... written in very much the same spirit as those of Mozart and Saint-Saëns," and said that "it uses certain effects borrowed from jazz, but only in moderation."

Flute sonata in G major (HWV 363b): The Flute sonata in G major (HWV 363b) was composed (c. 1711–16) by George Frideric Handel in F major for the oboe, and was transposed by an unknown hand to G major, for flute and keyboard (harpsichord).  The work is also referred to as "Opus 1 No. 5", as it was first published in 1726 or slightly later by the London publisher Walsh, in an edition falsely attributed to Jeanne Roger of Amsterdam.  Other catalogues of Handel's music have referred to the work as HG xxvii,19; and HHA iv/3,28.  The sonata was originally composed as an oboe sonata in F major (HWV 363a).
