Question: Alexander Borodin was part of a group of composers from what nationality?
Context: Mount Borodin ( ) is a mainly ice-covered mountain, 695 m high, with a rock outcrop on the east side, 7 nmi north-northeast of Gluck Peak in the southwest part of Alexander Island, Antarctica.  A number of peaks in this general vicinity first appear on the maps of the Ronne Antarctic Research Expedition (RARE), 1947–48.  This peak, apparently one of these, was mapped from RARE air photos by Derek J.H. Searle of the Falkland Islands Dependencies Survey in 1960, and named by the UK Antarctic Place-Names Committee after Alexander Borodin, the Russian composer. Stenka Razin, Op. 13, is a symphonic poem composed by Alexander Glazunov in 1885.  Dedicated to the memory of Alexander Borodin, it is one of the few compositions written by Glazunov on a nationalist subject and is composed in a style reminiscent of Borodin and Pyotr Ilyich Tchaikovsky. Russian Easter Festival Overture: Overture on Liturgical Themes (Russian: Светлый праздник, "Svetliy prazdnik" ), Op.  36, also known as the Great Russian Easter Overture, is a concert overture written by the Russian composer Nikolai Rimsky-Korsakov between August 1887 and April 1888.  It was dedicated to the memories of Modest Mussorgsky and Alexander Borodin, two members of the group of composers known in English as "The Five".  It is the last of what many call his three most exceptionally brilliant orchestral works, preceded by "Capriccio Espagnol" and "Scheherazade".  The work received its premiere at a Russian symphony concert in St. Petersburg in late December 1888. The Petite Suite is a suite of seven piano pieces, written by Alexander Borodin, and acknowledged as his major work for the piano.  It was published in 1885, although some of the pieces had been written as far back as the late 1870s.  After Borodin's death, Alexander Glazunov orchestrated the work, and added his orchestration of another of Borodin's pieces as an eighth number. The Hunsdiecker reaction (also called the Borodin reaction after Alexander Borodin) is the organic reaction of silver salts of carboxylic acids with halogens to give organic halides.  It is an example of a halogenation reaction.  The reaction is named after Heinz Hunsdiecker and Cläre Hunsdiecker, but was first noted by Borodin in 1861 when he prepared methyl bromide from silver acetate. The String Quartet No. 2 is a string quartet in D major written by Alexander Borodin in 1881.  It was dedicated to his wife Ekaterina Protopova.  Some scholars, such as Borodin’s biographer Serge Dianin, suggest that the quartet was a 20th anniversary gift and that it has a program evoking the couple’s first meeting in Heidelberg.  Of its four movements, the third movement “Notturno” is the most famous, and part of it was adapted into the song “And This Is My Beloved” from the 1953 Broadway musical "Kismet". In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether should be composed following Western or native practices.  Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics.  The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training.  While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression.  Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination.  Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print. Alexander Porfiryevich Borodin (Russian: Алекса́ндр Порфи́рьевич Бороди́н ; ] , 12 November 183327 February 1887) was a Russian Romantic composer of Georgian origin, as well as a doctor and chemist.  He was one of the prominent 19th century composers known as The Mighty Handful, a group dedicated to producing a uniquely Russian kind of classical music, rather than imitating earlier Western European models. Alexander Borodin's Scherzo in A-flat major is a lively piece written in 1885, while Borodin was in Belgium for an early performance of his then incomplete opera "Prince Igor".  It was originally written for solo piano but in 1889 Alexander Glazunov orchestrated it, along with the "Petite Suite".  Borodin dedicated the piece to Théodore Jadoul, who made a four-hand piano arrangement of it. The Mighty Handful (Russian: Могучая кучка ), also known as The Five and The New Russian School, were five prominent 19th-century Russian composers who worked together to create a distinctly Russian classical music.  Mily Balakirev (the leader), César Cui, Modest Mussorgsky, Nikolai Rimsky-Korsakov and Alexander Borodin all lived in Saint Petersburg, and collaborated from 1856 to 1870.
