Input: Consider Input: Passage: Tchaikovsky was born in 1840 in Votkinsk, a small town in present-day Udmurtia, formerly the Imperial Russian province of Vyatka. A precocious pupil, he began piano lessons at the age of five, and could read music as adeptly as his teacher within three years. However, his parents' passion for his musical talent soon cooled. In 1850, the family decided to send Tchaikovsky to the Imperial School of Jurisprudence in Saint Petersburg. This establishment mainly served the lesser nobility or gentry, and would prepare him for a career as a civil servant. As the minimum age for acceptance was 12, Tchaikovsky was sent by his family to board at the Imperial School of Jurisprudence's preparatory school in Saint Petersburg, 800 miles (1,300 km) from his family home in Alapayevsk. Once Tchaikovsky came of age for acceptance, he was transferred to the Imperial School of Jurisprudence to begin a seven-year course of studies.Music was not a priority at the School, but Tchaikovsky regularly attended the theater and the opera with other students. He was fond of works by Rossini, Bellini, Verdi and Mozart. Piano manufacturer Franz Becker made occasional visits to the School as a token music teacher. This was the only formal music instruction Tchaikovsky received there. From 1855 the composer's father, Ilya Tchaikovsky, funded private lessons with Rudolph Kündinger, a well-known piano teacher from Nuremberg, and questioned Kündinger about a musical career for his son. Kündinger replied that nothing suggested a potential composer or even a fine performer. Tchaikovsky was told to finish his course and then try for a post in the Ministry of Justice.Tchaikovsky graduated on May 25, 1859 with the rank of titular counselor, a low rung on the civil service ladder. On June 15, he was appointed to the Ministry of Justice in Saint Petersburg. Six months later he became a junior assistant and two months after that, a senior assistant. Tchaikovsky remained there for the rest of his three-year civil service career.In 1861, Tchaikovsky attended classes in music theory organized by the Russian Musical Society and taught by Nikolai Zaremba. A year later he followed Zaremba to the Saint Petersburg Conservatory. Tchaikovsky would not give up his Ministry post "until I am quite certain that I am destined to be a musician rather than a civil servant." From 1862 to 1865 he studied harmony, counterpoint and fugue with Zaremba, while Rubinstein taught him instrumentation and composition. In 1863 he abandoned his civil service career and studied music full-time, graduating in December 1865. 
Question: What is the name of the full name of the man that the titular counselor studied under starting in 1861?

Output: Nikolai Zaremba.


Input: Consider Input: Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.
