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:
Why were 78s more popular than 45s in 1954-55?, Context: Some of Elvis Presley's early singles on Sun Records might have sold more copies on 78 than on 45. This is because the majority of those sales in 1954–55 were to the "hillbilly" market in the South and Southwestern United States, where replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford at the time. By the end of 1957, RCA Victor announced that 78s accounted for less than 10% of Presley's singles sales, essentially announcing the death throes of the 78 rpm format. The last Presley single released on 78 in the United States was RCA Victor 20-7410, I Got Stung/One Night (1958), while the last 78 in the UK was RCA 1194, A Mess Of Blues/Girl Of My Best Friend (1960).

Ex Output:

Ex Input:
What kind of structure is suitable for people to live in on Frontage Road?, Context: A second biotechnology district is being planned for the median strip on Frontage Road, on land cleared for the never-built Route 34 extension. As of late 2009, a Pfizer drug-testing clinic, a medical laboratory building serving Yale – New Haven Hospital, and a mixed-use structure containing parking, housing and office space, have been constructed on this corridor. A former SNET telephone building at 300 George Street is being converted into lab space, and has been so far quite successful in attracting biotechnology and medical firms.

Ex Output:

housing
