Input: Consider Input: Question: In what year was Columbia University founded? Passage:Columbia (; ) is the female personification of the United States. It was also a historical name used to describe the Americas and the New World. It has given rise to the names of many persons, places, objects, institutions and companies; for example: Columbia University, the District of Columbia (the national capital of the United States), and the ship Columbia Rediviva, which would give its name to the Columbia River. Images of the Statue of Liberty largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. The District of Columbia is named after the personification, as is the traditional patriotic hymn "Hail Columbia", which is the official vice presidential anthem of the United States Vice President.

Input: Consider Input: Question: Of the musical acts Vixen toured with, which one has been active the longest? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

Input: Consider Input: Question: What is the mascot of the college that Binns received a Bachelor of Arts degree from in 1942? Passage:Born in Tacoma, Washington to an attorney and his wife who were active New Deal Democrats, Elizabeth Binns wanted to be a lawyer from a young age. Her father sometimes allowed her to skip classes in order to watch him try cases; she graduated from the local public high school at age 16. She then attended Stanford University and graduated with a Bachelor of Arts degree in 1942 at the age of 19. Because so many men were away during World War II, Binns was admitted to the Stanford Law School, and completed one year before marrying Robert L. Fletcher, who was soon assigned to fly anti-aircraft blimps out of Lakehurst, New Jersey. They started a family, and moved back to Lakewood, Washington, after the war. With her parents' assistance in caring for their four young children (and renting out their own house to live in Lakewood), Fletcher resumed her legal education after a decade, now commuting to Seattle to study at the University of Washington School of Law. In 1956 she graduated at the top of her law school class, with a Bachelor of Laws.
