In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Paraceratherium is an extinct genus of hornless rhinoceros, and one of the largest terrestrial mammals that has ever existed. It lived from the early to late Oligocene epoch (34–23 million years ago); its remains have been found across Eurasia between China and the Balkans. It is classified as a member of the hyracodont subfamily Indricotheriinae. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species P. bugtiense was originally placed.
The exact size of Paraceratherium is unknown because of the incompleteness of the fossils. Its weight is estimated to have been 15 to 20 tonnes (33,000 to 44,000 lb) at most; the shoulder height was about 4.8 metres (15.7 feet), and the length about 7.4 metres (24.3 feet). The legs were long and pillar-like. The long neck supported a skull that was about 1.3 metres (4.3 ft) long. It had large, tusk-like incisors and a nasal incision that suggests it had a prehensile upper lip or proboscis (trunk). The lifestyle of Paraceratherium may have been similar to that of modern large mammals such as the elephants and extant rhinoceroses. Because of its size, it would have had few predators and a slow rate of reproduction. It was a browser, eating mainly leaves, soft plants, and shrubs. It lived in habitats ranging from arid deserts with a few scattered trees to subtropical forests. The reasons for the animal's extinction are unknown, but various factors have been proposed. 
Question: What quality of Paraceratherium's probably meant it didn't have many animals trying to eat it?
its size.

Passage: The story begins with the Japanese army's defeat of the China forces occupying Hong Kong on 25 December 1941. Nicholas is an eleven-year-old boy whose  parents have both suddenly disappeared in the chaos of war breaking out.  As the Japanese come to do a home to home search, three loyal family servants, Tang, his wife Ah Mee, and the gardener Ah Kwan take Nicholas and they escape to Kowloon as Hong Kong Island is no longer safe. Upon reaching the shore of Kowloon, Tang and Ah Mee disguise Nicholas as a Chinese boy and the trip continues to Tang's home village, the village of Sek Wan.
Nicholas passes the years of the war here with Tang and his family. He is given the Chinese name Wing Ming. During this time, many events happen. Nicholas makes a dangerous journey back to Kowloon to get quinine cure to the malaria Tang has contracted. He also helps the Communist partisan army – The East River Column Fighters-  to translate instructions for using heavy explosives. Nicholas joins the partisan army on a mission to Kowloon where they blow up a railway bridge and weaken the position of the Japanese army. Yet his most dangerous job would have been to deliver a medicine into the prison of war camps (POW camps). Taking news or items to prison camps is nicknamed "playing music on the bamboo radio". Nicholas does more than expected by entering the camp itself because the person who he was supposed to pass the medicine to had the fever. Exhausted and worried, Nicholas narrowly escapes the clutches of the Japanese with the help of the prisoners and finally reaches the safety of Sek Wan village. 
Question: Where does Tang contract malaria?
the village of Sek Wan.

Passage: In 1919 Monteux was appointed chief conductor of the Boston Symphony Orchestra. The orchestra was going through difficult times; its conductor, Karl Muck, had been forced by anti-German agitation to step down in 1917. Sir Henry Wood turned down the post, and despite press speculation neither Sergei Rachmaninoff nor Arturo Toscanini was appointed. At least twenty-four players of German heritage had been forced out with Muck, and orchestral morale was low. Shortly before Monteux took up the conductorship the autocratic founder and proprietor of the orchestra, Henry Lee Higginson, died. He had steadfastly resisted unionisation, and after his death a substantial minority of the players resumed the struggle for union recognition. More than thirty players, including two important principals, resigned over the matter. Monteux set about rebuilding the orchestra, auditioning players from all kinds of musical background, some of whom had not played symphonic music before. By the end of his first season he had restored the orchestra to something approaching its normal complement. He trained the orchestra to a high standard; according to the critic Neville Cardus, Monteux's musicianship "made the Boston Symphony Orchestra the most refined and musical in the world."Monteux regularly introduced new compositions in Boston, often works by American, English and French composers.  He was proud of the number of novelties presented in his years at Boston, and expressed pleasure that his successors continued the practice. He was dismayed when it was announced that his contract would not be renewed after 1924. The official explanation was that the orchestra's policy had always been to appoint conductors for no more than five years. It is unclear whether that was genuinely the reason. One suggested possibility is that the conductor chosen to replace him, Serge Koussevitzky, was thought more charismatic, with greater box-office appeal. Another is that the primmer members of Boston society disapproved of Monteux's morals: he and his second wife had gradually drifted apart and by 1924 he was living with Doris Hodgkins, an American divorcée, and her two children. They were unable to marry until 1928, when Germaine Monteux finally agreed to a divorce. 
Question: What is the full name of the person that replaced Monteux as chief conductor?

Serge Koussevitzky.
