In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
What is not a source of interspersed repeats: transposable elements or genome evolution?, Context: Interspersed repeats mainly come from transposable elements (TEs), but they also include some protein coding gene families and pseudogenes. Transposable elements are able to integrate into the genome at another site within the cell. It is believed that TEs are an important driving force on genome evolution of higher eukaryotes. TEs can be classified into two categories, Class 1 (retrotransposons) and Class 2 (DNA transposons).

Ex Output:
genome evolution

Ex Input:
What happened earlier, the French invasion in 1672 or Utrecht becoming the centre of the non-Roman Old Catholic Churches in the world?, Context: The fortified city temporarily fell to the French invasion in 1672 (the Disaster Year); where the French invasion was only stopped west of Utrecht at the Old Hollandic Waterline. In 1674, only two years after the French left, the centre of Utrecht was struck by a tornado. The halt to building before construction of flying buttresses in the 15th century now proved to be the undoing of the central section of the cathedral of St Martin church which collapsed; creating the current Dom square between the tower and choir. In 1713, Utrecht hosted one of the first international peace negotiations when the Treaty of Utrecht settled the War of the Spanish Succession. Since 1723 Utrecht became the centre of the non-Roman Old Catholic Churches in the world.

Ex Output:
the French invasion in 1672

I'm an athlete; what features would attract me most about this university?, Context: Since the construction of its oldest buildings, the university's physical plant has grown substantially. Over the years 29 residence halls have been built to accommodate students and each has been constructed with its own chapel. Many academic building were added together with a system of libraries, the most prominent of which is the Theodore Hesburgh Library, built in 1963 and today containing almost 4 million books. Since 2004, several buildings have been added, including the DeBartolo Performing Arts Center, the Guglielmino Complex, and the Jordan Hall of Science. Additionally, a new residence for men, Duncan Hall, was begun on March 8, 2007, and began accepting residents for the Fall 2008 semester. Ryan Hall was completed and began housing undergraduate women in the fall of 2009. A new engineering building, Stinson-Remick Hall, a new combination Center for Social Concerns/Institute for Church Life building, Geddes Hall, and a law school addition have recently been completed as well. Additionally the new hockey arena opened in the fall of 2011. The Stayer Center for Executive Education, which houses the Mendoza College of Business Executive Education Department opened in March 2013 just South of the Mendoza College of Business building. Because of its long athletic tradition, the university features also many building dedicated to sport. The most famous is Notre Dame Stadium, home of the Fighting Irish football team; it has been renovated several times and today it can hold more than 80 thousand people. Prominent venues include also the Edmund P. Joyce Center, with indoor basketball and volleyball courts, and the Compton Family Ice Arena, a two-rink facility dedicated to hockey. Also, there are many outdoor fields, as the Frank Eck Stadium for baseball.
