Question: Keane was born into a working class family in Ballinderry Park, Mayfield, Cork. His father, Maurice, took work wherever he could find, which led to jobs at a local knitwear company and at Murphy's Irish Stout brewery, among others. His family were keen on sport, football especially, and many of his relatives had played for junior clubs in Cork, including Rockmount. Keane took up boxing at the age of nine and trained for a number of years, winning all of his four bouts in the novice league.

Despite the then-record transfer fee, there was no guarantee that Keane would go straight into the first team. Paul Ince and Bryan Robson had established a formidable partnership in the centre of midfield, having just inspired Manchester United to their first league title since 1967. Robson, however, was 36 years old and in the final stages of his playing career, and a series of injuries kept him out of action for most of the 1992-93 season and into the 1993-94 season. As a result Keane had an extended run in the team, scoring twice on his home debut in a 3-0 win against Sheffield United, and grabbing the winner in the Manchester derby three months later when United overturned a 2-0 deficit at Maine Road to beat Manchester City 3-2.  Keane had soon established himself as a first choice selection, and by the end of the season he had won his first trophy as a professional as United retained their Premier League title. Two weeks later, Keane broke his Wembley losing streak by helping United to a 4-0 victory over Chelsea in the FA Cup Final, sealing the club's first ever "double".  The following season was less successful, as United were beaten to the league title by Blackburn Rovers and beaten 1-0 in the FA Cup final by Everton. He received his first red card as a Manchester United player in a 2-0 FA Cup semi-final replay win against Crystal Palace, after stamping on Gareth Southgate, and was suspended for three matches and fined PS5,000. This incident was the first of 11 red cards Keane would accumulate in his United career, and one of the first signs of his indiscipline on the field.  The summer of 1995 saw a period of change at United, with Ince leaving for Internazionale, Mark Hughes moving to Chelsea and Andrei Kanchelskis being sold to Everton. Younger players such as David Beckham, Nicky Butt and Paul Scholes were brought into the team, which left Keane as the most experienced player in midfield. Despite a slow start to the 1995-96 campaign, United pegged back title challengers Newcastle United, who had built a commanding 12-point championship lead by Christmas, to secure another Premier League title. Keane's second double in three years was confirmed with a 1-0 win over Liverpool to win the FA Cup for a record ninth time.  The next season saw Keane in and out of the side due to a series of knee injuries and frequent suspensions. He picked up a costly yellow card in the first leg of the Champions League semi-final against Borussia Dortmund, which ruled him out of the return leg at Old Trafford. United lost both legs 1-0, but this was compensated for by winning another league title a few days later.

Answer: 

Problem: Irving Grant Thalberg (May 30, 1899 - September 14, 1936) was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, Camille, Mutiny on the Bounty, and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom," states biographer Roland Flamini.

Thalberg was born in Brooklyn, to German Jewish immigrant parents, William and Henrietta (Haymann). Shortly after birth, he was diagnosed with "blue baby syndrome," caused by a congenital disease that limited the oxygen supply to his heart. The prognosis from the family's doctor and specialists was that he might live to age twenty, or at most, age thirty.  During his high school years in Brooklyn, he began having attacks of chest pains, dizziness and fatigue. This affected his ability to study, though until that time he was a good student. When he was 17, he contracted rheumatic fever, and was confined to bed for a year. His mother, Henrietta, to prevent him falling too far behind other students, brought him homework from school, books, and tutors to teach him at home. She also hoped that the schoolwork and reading would distract him from the "tantalizing sounds" of children playing outside his window.  With little to entertain him, he read books as a main activity. He devoured popular novels, classics, plays, and biographies. His books, of necessity, replaced the streets of New York, and led to his interest in classical philosophy and philosophers, such as William James.  When Thalberg returned to school, he finished high school but lacked the stamina for college, which he felt would have required constant late-night studying and cramming for exams. Instead, he took part-time jobs as a store clerk, and in the evenings, to gain some job skills, taught himself typing, shorthand and Spanish at a night vocational school. When he turned 18, he placed an ad with the local newspaper hoping to find better work:  "Situation Wanted: Secretary, stenographer, Spanish, English, high school education, no experience; $15."
