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?

Ex Output:
Lawrence.

Passage: Living in Manhattan, Tom is a cook who has difficulty keeping a steady job. His wife, Sofia, is an attorney. When their first child is born, they agree that she will be a full-time mom and he will work hard to get a promotion. When Tom gets fired after defending his friend Paco, he takes a job in Ohio working at the ad agency where his father-in-law is the assistant director. Tom is assigned to report to Chip. Chip is a strict and hard-working paraplegic man who is coincidentally Sofia's ex-boyfriend from high school. Chip still carries an obsession with her, so he conspires to make Tom's work life miserable. As Tom's frustrations mount, Chip begins to sway Sofia to his side.
Tom begins to suspect that Chip isn't handicapped at all and goes through his desk. He finds a photo of Chip playing tennis and rushes to his in-laws' house to see his wife and show her the picture. He finds Chip having dinner with Sofia and her parents and holding Tom's child. Tom mercilessly tries to prove that Chip isn't actually paralyzed by dragging him up a flight of stairs and then throws him, expecting him to stand up to prevent falling. Chip doesn't stand up and Tom is humiliated in front of his family. Later, he confronts Chip outside his house and attacks him, where Chip reveals that he really can walk, but can't fight outside of his chair. After sitting back down, Chip beats him severely and reveals that he plans to sleep with Sofia, much to Tom's already-increased rage. 
Question: Who's wife did the paraplegic man date in high school?

Ex Output:
Tom.

Passage: Half-witted longtime friends Albert, Isaac, Mozart "Mo" (DJ Durano), Michaelangelo "Mike" (Martin Escudero) and  Aristotle "Aris" (Marvin Agustin) were used to living moronic yet pretty normal and hassle-free lives until successful careerwoman Beckie Pamintuan accused them of killing her father and ruin everything for them. The Moron 5 are more than sure of their innocence but for the life of them, they can't find any single satisfactory argument on how to prove it especially when their opponent would do everything to punish them for whim. Spending three miserable years in prison trying different failed comedic attempts to get out, they finally figured a way to escape. They stalked Beckie and tried to understand why she's fighting so hard to have them imprisoned when it's clear as day that what happened three years ago was a nonsense frame-up. An opportunity came when Beckie's driver got fired for having an affair with her maid and Albert volunteered to apply to replace him. He infiltrated the Pamintuan Residence and together with his four crazily daft friends, they've gathered information about the curious family yet to them, it isn't making any sense at all especially Vecky's unexplained hatred to the five of them. Why is Beckie fighting so hard to have them suffer? The Moron 5 will try harder to know and hopefully understand what's really going on although little did they know that by doing so, everything that they hold dear might be at risk. 
Question: What are the first names of the four crazily daft friends that helped Albert gather information about the Pamintuan family?

Ex Output:

Isaac.
