Question: Passage: Consulting detective Sherlock Holmes fakes his own death in Scotland in order to investigate a number of bizarre apparent suicides that he is convinced are part of an elaborate plot by "a female Moriarty". Returning to his assistant Watson in secret, Holmes notes that all the victims were wealthy gamblers, so disguised as "Rajni Singh", a distinguished Indian officer, he stalks London's gaming clubs.
It is not long before he encounters the villain of the piece, Adrea  Spedding. Holmes discovers that she seeks out men short of money, persuades them to pawn their life insurance policies with her accomplices, then kills them. Holmes sets himself up as her next victim, discovering that she uses the deadly spider, Lycosa Carnivora, whose venom causes such excruciating pain that the victims kill themselves. Holmes also finds the footprint of a child nearby.
Searching for evidence Holmes and Watson visit eminent arachnologist Matthew Ordway, who may have supplied the deadly creatures. Holmes soon realizes that the man he is speaking to is an impostor, but the villain makes his escape. Searching the premises, Holmes finds the corpse of the real Ordway, as well as his journals, which allude to something or someone from Central Africa immune to the spider venom. This baffles Holmes until he finds the model skeleton of a child. However, Dr. Watson points out that the relation of the skull and the circumference of the chest prove it is not a child, and Holmes deduces that the Central African thing described in the journal is a pygmy.
Holmes and Watson continue their investigations at a nearby fairground, where Holmes allows himself to fall into the clutches of Spedding and her gang. Bound and gagged, Holmes is tied behind a moving target in a shooting gallery, at which Lestrade and Watson take pot shots with a  .22 rifle. However Holmes manages to escape, and Lestrade and the police arrest Spedding, her gang, and the pygmy. 
Question: What is the last name of the person who might have given the Lycosa Carnivora to Adrea?

Answer: Ordway.


Question: 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?

Answer: Nikolai Zaremba.


Question: Passage: The film starts off with a scene from the novel Moby Dick, with a whaler on a stormy sea in the 19th century, chasing "the white whale". It turns out that the scene comes from the imagination of Dot, while she is sitting with the book. She goes out to play with Nelson the dolphin in his pool, and he teaches her how to stay underwater for long periods of time and to communicate underwater, as well as the history and evolution of sea creatures.
While they play together, Nelson hears the wail of a beached whale named "Tonga" from the local coast, and jumps out of his pool, over the cliff beside, and dives into the ocean on the other side, to check what is going on, with Dot coming along. Dot walks up on land to talk with Tonga, but becomes upset as two boys, Alex and Owen, stand and throw sand on the whale. The boys say that they only want to push the whale back to the sea. Together, they try to push Tonga back to the water, but fail. They decide to gather as many kids as possible, in order to help the whale as much as they can.
While Alex and Owen start to gather help, Dot sits beside Tonga, trying to converse. Tonga explains that her family has been killed by whalers, and she is the only survivor, but has lost the will to live. Dot explains that she and others want to help Tonga, and tries to by having Tonga placed in the same pool as Nelson to let her recover. Dot then realizes that they do not have a transport facility for a whale. Meanwhile, a crooked fishmonger becomes interested in Tonga as a possible "Fish" source. 
Question: What is the first name of the character who the boys throw sand on?

Answer:
Tonga.
