Problem: Background: Kintaro Hayakawa (June 10, 1889 - November 23, 1973), known professionally as Sessue Hayakawa, was a Japanese actor. He was one of the biggest stars in Hollywood during the silent film era of the 1910s and 1920s. Hayakawa was the first actor of Asian descent to achieve stardom as a leading man in the United States and Europe. His "broodingly handsome" good looks and typecasting as a sexually dominant villain made him a heartthrob among American women during a time of racial discrimination, and he became one of the first male sex symbols of Hollywood.
Context: Hayakawa was born Kintaro Hayakawa (Zao Chuan Jin Tai Lang , Hayakawa Kintaro) in the village of Nanaura, now part of a town called Chikura, in the city of Minamiboso in Chiba Prefecture, Japan, on June 10, 1889. From an early age, Hayakawa's family intended him to become an officer in the Imperial Japanese Navy. However, while a student at the naval academy in Etajima, he swam to the bottom of a lagoon (he grew up in a shellfish diving community) on a dare and ruptured his eardrum. The injury caused him to fail the navy physical. His father felt shame and embarrassment by his son's failure and this drove a wedge between them. The strained relationship drove the 18-year-old Hayakawa to attempt seppuku (ritual suicide). One evening, Hayakawa entered a shed on his parents' property and prepared the venue. He put his dog outside and attempted to uphold his family's samurai tradition by stabbing himself more than 30 times in the abdomen. The barking dog brought Hayakawa's parents to the scene and his father used an axe to break down the door, saving his life. After he recovered from the suicide attempt, Hayakawa began to study political economics at the University of Chicago to fulfill his family's new wish that he become a banker. While a student, he played quarterback for the football team and was once penalized for using jujitsu to bring down an opponent. Hayakawa graduated from the University of Chicago in 1912, and subsequently made plans to return to Japan. He traveled to Los Angeles and awaited a transpacific steamship. During his stay, he discovered the Japanese Theatre in Little Tokyo and became fascinated with acting and performing plays. It was around this time that Hayakawa first assumed the stage name Sessue (Xue Zhou , Sesshu), meaning "snowy field" (Xue means "snow" and Zhou means "north field"). One of the productions in which Hayakawa performed was called The Typhoon. Tsuru Aoki, a member of the acting troupe, was so impressed with Hayakawa's abilities and enthusiasm that she enticed film producer Thomas H. Ince to see the play. Ince saw the production and offered to turn it into a silent film with the original cast. Anxious to return to Japan, Hayakawa tried to dissuade Ince by requesting the then-astronomic fee of $500 a week, but Ince agreed to his request. The Typhoon (1914) became an instant hit and was followed by two additional pictures produced by Ince, The Wrath of the Gods (1914) co-starring Hayakawa's new wife, Aoki, and The Sacrifice (1914). With Hayakawa's rising stardom, Jesse L. Lasky soon offered Hayakawa a contract, which he accepted, making him part of Famous Players-Lasky (now Paramount Pictures).
Question: What injury?
Answer: ruptured his eardrum.

Problem: Background: Sarvepalli Radhakrishnan listen (5 September 1888 - 17 April 1975) was an Indian philosopher and statesman who was the first Vice President of India (1952-1962) and the second President of India from 1962 to 1967. One of India's most distinguished twentieth-century scholars of comparative religion and philosophy, his academic appointments included professor of Philosophy at the University of Mysore (1918-1921), the King George V Chair of Mental and Moral Science at the University of Calcutta (1921-1932) and Spalding Professor of Eastern Religion and Ethics at University of Oxford (1936-1952). His philosophy was grounded in Advaita Vedanta, reinterpreting this tradition for a contemporary understanding.
Context: In April 1909, Sarvepalli Radhakrishnan was appointed to the Department of Philosophy at the Madras Presidency College. Thereafter, in 1918, he was selected as Professor of Philosophy by the University of Mysore, where he taught at its Maharaja's College, Mysore. By that time he had written many articles for journals of repute like The Quest, Journal of Philosophy and the International Journal of Ethics. He also completed his first book, The Philosophy of Rabindranath Tagore. He believed Tagore's philosophy to be the "genuine manifestation of the Indian spirit". His second book, The Reign of Religion in Contemporary Philosophy was published in 1920. In 1921 he was appointed as a professor in philosophy to occupy the King George V Chair of Mental and Moral Science at the University of Calcutta. He represented the University of Calcutta at the Congress of the Universities of the British Empire in June 1926 and the International Congress of Philosophy at Harvard University in September 1926. Another important academic event during this period was the invitation to deliver the Hibbert Lecture on the ideals of life which he delivered at Harris Manchester College, Oxford in 1929 and which was subsequently published in book form as An Idealist View of Life. In 1929 Radhakrishnan was invited to take the post vacated by Principal J. Estlin Carpenter at Harris Manchester College. This gave him the opportunity to lecture to the students of the University of Oxford on Comparative Religion. For his services to education he was knighted by George V in the June 1931 Birthday Honours, and formally invested with his honour by the Governor-General of India, the Earl of Willingdon, in April 1932. However, he ceased to use the title after Indian independence, preferring instead his academic title of 'Doctor'. He was the Vice-Chancellor of Andhra University from 1931 to 1936. In 1936 Radhakrishnan was named Spalding Professor of Eastern Religions and Ethics at the University of Oxford, and was elected a Fellow of All Souls College. That same year, and again in 1937, he was nominated for the Nobel Prize in Literature, although this nomination process, as for all laureates, was not public at the time. Further nominations for the award would continue steadily into the 1960s. In 1939 Pt. Madan Mohan Malaviya invited him to succeed him as the Vice-Chancellor of Banaras Hindu University (BHU). He served as its Vice-Chancellor till January 1948.
