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

Example Input: Who was responsible for Universal before Junior?, Context: "Junior" Laemmle persuaded his father to bring Universal up to date. He bought and built theaters, converted the studio to sound production, and made several forays into high-quality production. His early efforts included the critically mauled part-talkie version of Edna Ferber's novel Show Boat (1929), the lavish musical Broadway (1929) which included Technicolor sequences; and the first all-color musical feature (for Universal), King of Jazz (1930). The more serious All Quiet on the Western Front (1930), won its year's Best Picture Oscar.
Example Output: his father

Example 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).
Example Output: genome evolution

Example Input: what do the seasons have to do to create annual rings, Context: In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
Example Output:
differences in the character of the elements
