Passage: The music video for "Single Ladies" was shot immediately after that of "If I Were a Boy", but it received less attention during production than the "higher-gloss, higher-profile video" for "If I Were a Boy". Both videos were shot in black-and-white in New York City and were directed by Jake Nava, with whom Beyoncé had worked on previous music videos including "Crazy in Love" and "Beautiful Liar". "Single Ladies" was choreographed by Frank Gatson Jr. and JaQuel Knight, and incorporates J-Setting choreography. The two music videos premiered on MTV's Total Request Live show on October 13, 2008 to reinforce the concept of conflicting personalities. The videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography, Above and Beyoncé, and the platinum edition of I Am... Sasha Fierce.
Beyoncé told Simon Vozick-Levinson of Entertainment Weekly that the inspiration for the video was a 1969 Bob Fosse routine entitled "Mexican Breakfast" seen on The Ed Sullivan Show, which featured Fosse's wife, Gwen Verdon, dancing with two other women. "Mexican Breakfast" had become an Internet viral sensation the previous summer after Unk's "Walk It Out" was dubbed over the original mix. Beyoncé wanted to attempt a similar dance and eventually, the choreography of "Single Ladies" was liberally adapted from "Mexican Breakfast":
I saw a video on YouTube. [The dancers] had a plain background and it was shot on the crane; it was 360 degrees, they could move around. And I said, 'This is genius.' We kept a lot of the Fosse choreography and added the down-south thing—it's called J-Setting, where one person does something and the next person follows. So it was a strange mixture ... It's like the most urban choreography, mixed with Fosse—very modern and very vintage. 
Question: What  videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography?

Ex Output:
Single Ladies.

Ex Input:
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. 
Question: Who transferred to the engineering program at MIT?

Ex Output:

Pei.
