Problem: Background: Yo-Yo Ma (born October 7, 1955) is a French-born American cellist. Born in Paris, he spent his schooling years in New York City and was a child prodigy, performing from the age of four and a half. He graduated from the Juilliard School and Harvard University and has enjoyed a prolific career as both a soloist performing with orchestras around the world and a recording artist. He has recorded more than 90 albums and received 18 Grammy Awards.
Context: Yo-Yo Ma was born in Paris on October 7, 1955, to Chinese parents and had a musical upbringing. His mother, Marina Lu, was a singer and his father, Hiao-Tsiun Ma, was a violinist and professor of music at Nanjing National Central University (predecessor of the present-day Nanjing University). His sister, Yeou-Cheng Ma, played the violin before obtaining a medical degree and becoming a pediatrician. The family moved to New York when Ma was seven years old.  At a young age, Ma began studying violin and piano and later viola, finally settling on the cello in 1960 at age four. According to Ma, his first choice was the double bass due to its large size, but he compromised and took up cello instead. The child prodigy began performing before audiences at age five and performed for Presidents Dwight D. Eisenhower and John F. Kennedy when he was seven. At age eight, he appeared on American television with his sister, Yeou-Cheng Ma, in a concert conducted by Leonard Bernstein. In 1964, Isaac Stern introduced them on The Tonight Show Starring Johnny Carson, and they performed the Sonata of Sammartini. He attended Trinity School in New York but transferred to the Professional Children's School, from which he graduated at age 15. He appeared as a soloist with the Harvard Radcliffe Orchestra in a performance of the Tchaikovsky Rococo Variations.  Ma studied at The Juilliard School at age 19 with Leonard Rose and attended Columbia University but dropped out. He later enrolled at Harvard College. Prior to entering Harvard, Ma played in the Marlboro Festival Orchestra under the direction of cellist and conductor Pablo Casals. Ma would ultimately spend four summers at the Marlboro Music Festival after meeting and falling in love with Mount Holyoke College sophomore and festival administrator Jill Hornor his first summer there in 1972.  However, even before that time, Ma had steadily gained fame and had performed with many of the world's major orchestras. He has also played chamber music, often with the pianist Emanuel Ax, with whom he has a close friendship back from their days together at the Juilliard School of Music in New York. Ma received his bachelor's degree from Harvard in 1976. In 1991, he received an honorary doctorate from Harvard.
Question: When did he move to America?
Answer: The family moved to New York when Ma was seven years old.

Problem: Background: La Strada (lit. "The Road") is a 1954 Italian drama film directed by Federico Fellini from his own screenplay co-written with Tullio Pinelli and Ennio Flaiano. The film portrays a naive young woman (Giulietta Masina) bought from her mother by a brutish strongman (Anthony Quinn) who takes her with him on the road. Fellini has called La Strada "a complete catalogue of my entire mythological world, a dangerous representation of my identity that was undertaken with no precedent whatsoever."
Context: In later years, Fellini explained that from "a sentimental point of view," he was "most attached" to La Strada: "Above all, because I feel that it is my most representative film, the one that is the most autobiographical; for both personal and sentimental reasons, because it is the film that I had the greatest trouble in realizing and that gave me the most difficulty when it came time to find a producer." Of all the imaginary beings he had brought to the screen, Fellini felt closest to the three principals of La Strada, "especially Zampano." Anthony Quinn found working for Fellini invaluable: "He drove me mercilessly, making me do scene after scene over and over again until he got what he wanted. I learned more about film acting in three months with Fellini than I'd learned in all the movies I'd made before then." Long afterwards, in 1990, Quinn sent a note to the director and his co-star: "The two of you are the highest point in my life -- Antonio."  Critic Roger Ebert, in his book The Great Movies, has described the current critical consensus as holding that La Strada was the high point of Fellini's career and that, after this film, "his work ran wild through the jungles of Freudian, Christian, sexual and autobiographical excess". (Ebert, himself, disagrees, seeing La Strada as "part of a process of discovery that led to the masterpieces La Dolce Vita (1960), 8 1/2 (1963) and Amarcord (1974)".)  The years since its initial release have solidified the high estimation of La Strada. It holds a 97% rating on the review aggregator website Rotten Tomatoes from 31 reviewers who, on average, scored it 8.7 on a scale of 10. Its numerous appearances on lists of best films include the 1992 Directors' poll of the British Film Institute (4th best), the New York Times "Best 1,000 Movies Ever Made", and the "Greatest Films" list of They Shoot Pictures, Don't They (# 67) - a website that statistically calculates the most well-received movies.  In 1995, the Catholic Church's Pontifical Commission for Social Communications issued a list of 45 films representing a "...cross section of outstanding films, chosen by a committee of twelve international movie scholars." This has come to be known as the Vatican film list, and includes La Strada as one of 15 films in the sub-category labeled Art. Pope Francis, has said it is "the movie that perhaps I loved the most," because of his personal identification with its implicit reference to his namesake, Francis of Assisi.
