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.

Example Input: Passage: Balakirev's despotism strained the relationship between him and Tchaikovsky but both men still appreciated each other's abilities. Despite their friction, Balakirev proved the only man to persuade Tchaikovsky to rewrite a work several times, as he would with Romeo and Juliet. At Balakirev's suggestion, Tchaikovsky based the work on Balakirev's King Lear, a tragic overture in sonata form after the example of Beethoven's concert overtures. It was Tchaikovsky's idea to reduce the plot to one central conflict and represent it musically with the binary structure of sonata form. However, the execution of that plot in the music we know today came only after two radical revisions. Balakirev discarded many of the early drafts Tchaikovsky sent him and, with the flurry of suggestions between the two men, the piece was constantly in the mail between Moscow and Saint Petersburg.Tchaikovsky allowed the first version to be premiered by Nikolai Rubinstein on March 16, 1870, after the composer had incorporated only some of Balakirev's suggestions. The premiere was a disaster. Stung by this rejection, Tchaikovsky took Balakirev's strictures to heart. He forced himself to reach beyond his musical training and rewrote much of the music into the form we know it today. Romeo would bring Tchaikovsky his first national and international acclaim and become a work the kuchka lauded unconditionally. On hearing the love theme from Romeo, Stasov told the group, "There were five of you; now there are six". Such was the enthusiasm of the Five for Romeo that at their gatherings Balakirev was always asked to play it through at the piano. He did this so many times that he learned to perform it from memory.Some critics, among them Tchaikovsky biographers Lawrence and Elisabeth Hanson, have wondered what would have happened if Tchaikovsky had joined Balakirev in 1862 instead of attending the Conservatory. They suggest that he might have developed much more quickly as an independent composer, and offer as proof the fact that Tchaikovsky did not write his first wholly distinct work until Balakirev goaded and inspired him to write Romeo. How well Tchaikovsky might have developed in the long run is another matter. He owed much of his musical ability, including his skill at orchestration, to the thorough grounding in counterpoint, harmony and musical theory he received at the Conservatory. Without that grounding, Tchaikovsky might not have been able to write what would become his greatest works. 
Question: What was the first names of Tchaikovsky's two biographers?
Example Output: Lawrence.

Example Input: Passage: In early 1970, Lennon and the Beatles' manager, Allen Klein, turned over the recordings to American producer Phil Spector with the hope of salvaging an album, which was then titled Let It Be. McCartney had become estranged from his bandmates at this time, due to his opposition to Klein's appointment as manager. Several weeks were lost before McCartney replied to messages requesting his approval for Spector to begin working on the recordings. Spector chose to return to the same 26 January recording of "The Long and Winding Road".Spector made various changes to the songs. His most dramatic embellishments occurred on 1 April 1970, the last ever Beatles recording session, when he added orchestral overdubs to "The Long and Winding Road", "Across the Universe" and "I Me Mine" at Abbey Road Studios. The only member of the Beatles present was Starr, who played drums with the session musicians to create Spector's characteristic "Wall of Sound". Already known for his eccentric behaviour in the studio, Spector was in a peculiar mood that day, according to balance engineer Peter Bown: "He wanted tape echo on everything, he had to take a different pill every half hour and had his bodyguard with him constantly. He was on the point of throwing a wobbly, saying 'I want to hear this, I want to hear that. I must have this, I must have that.'" The orchestra became so annoyed by Spector's behaviour that the musicians refused to play any further; at one point, Bown left for home, forcing Spector to telephone him and persuade him to come back after Starr had told Spector to calm down.Spector succeeded in overdubbing "The Long and Winding Road", using eight violins, four violas, four cellos, three trumpets, three trombones, two guitars, and a choir of 14 women, which makes 38 musicians altogther. The orchestra was scored and conducted by Richard Hewson, a young London arranger who had worked with Apple artists Mary Hopkin and James Taylor. This lush orchestral treatment was in direct contrast to the Beatles' stated intentions for a "real" recording when they began work on Get Back.On 2 April, Spector sent each of the Beatles an acetate of the completed album with a note saying: "If there is anything you'd like done to the album, let me know and I'll be glad to help ... If you wish, please call me about anything regarding the album tonight." All four of the band members sent him their approval by telegram. 
Question: What is the full name of the person that made dramatic embellishments on 1 April 1970?
Example Output: Phil Spector.

Example Input: Passage: Between the first and second season of promenade concerts, Wood did his last work in the opera house, conducting Stanford's new opera Shamus O'Brien at the Opera Comique. It ran from March until July 1896, leaving Wood enough time to prepare the second Queen's Hall season, which began at the end of August. The season was so successful that Newman followed it with a winter season of Saturday night promenade concerts, but despite being popular they were not a financial success, and were not repeated in later years. In January 1897 Wood took on the direction of the Queen's Hall's prestigious Saturday afternoon symphony concerts. He continually presented new works by composers of many nationalities, and was particularly known for his skill in Russian music. Sullivan wrote to him in 1898, "I have never heard a finer performance in England than that of the Tchaikovsky symphony under your direction last Wednesday". Seventy-five years later, Sir Adrian Boult ranked Wood as one of the two greatest Tchaikovsky conductors in his long experience. Wood also successfully challenged the widespread belief that Englishmen were not capable of conducting Wagner. When Wood and the Queen's Hall Orchestra performed at Windsor Castle in November 1898, Queen Victoria chose Tchaikovsky and Wagner for the programme. Wood, who modelled his appearance on Nikisch, took it as a compliment that the queen said to him, "Tell me, Mr Wood, are you quite English?"In 1898, Wood married one of his singing pupils, Olga Michailoff, a divorcée a few months his senior. Jacobs describes it as "a marriage of perfect professional and private harmony". As a singer, with Wood as her accompanist, she won praise from the critics. 
Question: What was the name of the person that conducted the Tchaikovsky symphony?
Example Output:
Wood.
