Example Input: Passage: BSkyB's standard definition broadcasts are in DVB-compliant MPEG-2, with the Sky Movies and Sky Box Office channels including optional Dolby Digital soundtracks for recent films, although these are only accessible with a Sky+ box. Sky+ HD material is broadcast using MPEG-4 and most of the HD material uses the DVB-S2 standard.

Sky News, amongst other channels, provides a pseudo-video on demand interactive service by broadcasting looping video streams. Question: Sky Movies and Sky Box office also include what optional soundtracks?

Example Input: Passage: The V&A has its origins in the Great Exhibition of 1851, with which Henry Cole, the museum's first director, was involved in planning; initially it was known as the Museum of Manufactures, first opening in May 1852 at Marlborough House, but by September had been transferred to Somerset House. At this stage the collections covered both applied art and science. Several of the exhibits from the Exhibition were purchased to form the nucleus of the collection. By February 1854 discussions were underway to transfer the museum to the current site and it was renamed South Kensington Museum. In 1855 the German architect Gottfried Semper, at the request of Cole, produced a design for the museum, but it was rejected by the Board of Trade as too expensive. The site was occupied by Brompton Park House; this was extended including the first refreshment rooms opened in 1857, the museum being the first in the world to provide such a facility. Question: The V&A has its origins in which world exposition?
Example Output: Great Exhibition of 1851

Example Input: Passage: Orientalism, as theorized by Edward Said, refers to how the West developed an imaginative geography of the East. This imaginative geography relies on an essentializing discourse that represents neither the diversity nor the social reality of the East. Rather, by essentializing the East, this discourse uses the idea of place-based identities to create difference and distance between 'we' the West and 'them' the East, or 'here' in the West and 'there' in the East. This difference was particularly apparent in textual and visual works of early European studies of the Orient that positioned the East as irrational and backward in opposition to the rational and progressive West. Defining the East as a negative vision of itself, as its inferior, not only increased the West’s sense of self, but also was a way of ordering the East and making it known to the West so that it could be dominated and controlled. The discourse of Orientalism therefore served as an ideological justification of early Western imperialism, as it formed a body of knowledge and ideas that rationalized social, cultural, political, and economic control of other territories. Question: The West saw themselves as what compared to the east?
Example Output:
rational and progressive
