Task: Question Answering
Input (English): Passage: As Pei, neared the end of his secondary education, he decided to study at a university. He was accepted to a number of schools, but decided to enroll at the University of Pennsylvania. Pei's choice had two roots. While studying in Shanghai, he had closely examined the catalogs for various institutions of higher learning around the world. The architectural program at the University of Pennsylvania stood out to him. The other major factor was Hollywood. Pei was fascinated by the representations of college life in the films of Bing Crosby, which differed tremendously from the academic atmosphere in China. "College life in the U.S. seemed to me to be mostly fun and games", he said in 2000. "Since I was too young to be serious, I wanted to be part of it ... You could get a feeling for it in Bing Crosby's movies. College life in America seemed very exciting to me. It's not real, we know that. Nevertheless, at that time it was very attractive to me. I decided that was the country for me."In 1935 Pei boarded a boat and sailed to San Francisco, then traveled by train to Philadelphia. What he found, however, differed vastly from his expectations. Professors at the University of Pennsylvania based their teaching in the Beaux-Arts style, rooted in the classical traditions of Greece and Rome. Pei was more intrigued by modern architecture, and also felt intimidated by the high level of drafting proficiency shown by other students. He decided to abandon architecture and transferred to the engineering program at Massachusetts Institute of Technology (MIT). Once he arrived, however, the dean of the architecture school commented on his eye for design and convinced Pei to return to his original major.MIT's architecture faculty was also focused on the Beaux-Arts school, and Pei found himself uninspired by the work. In the library he found three books by the Swiss-French architect Le Corbusier. Pei was inspired by the innovative designs of the new International style, characterized by simplified form and the use of glass and steel materials. Le Corbusier visited MIT in November 1935, an occasion which powerfully affected Pei: "The two days with Le Corbusier, or 'Corbu' as we used to call him, were probably the most important days in my architectural education." Pei was also influenced by the work of US architect Frank Lloyd Wright. In 1938 he drove to Spring Green, Wisconsin, to visit Wright's famous Taliesin building. After waiting for two hours, however, he left without meeting Wright.
