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

Q: What do you need in addition to the LaserDisc in order to experience surround sound?, Context: Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser. A fully capable LaserDisc playback system includes a newer LaserDisc player that is capable of playing digital tracks, has a digital optical output for digital PCM and DTS audio, is aware of AC-3 audio tracks, and has an AC-3 coaxial output; an external or internal AC-3 RF demodulator and AC-3 decoder; and a DTS decoder. Many 1990s A/V receivers combine the AC-3 decoder and DTS decoder logic, but an integrated AC-3 demodulator is rare both in LaserDisc players and in later A/V receivers.

A: playback equipment

Q: What was special about Deja Vu?, Context: The feminism and female empowerment themes on Beyonce's second solo album B'Day were inspired by her role in Dreamgirls and by singer Josephine Baker. Beyonce paid homage to Baker by performing "Deja Vu" at the 2006 Fashion Rocks concert wearing Baker's trademark mini-hula skirt embellished with fake bananas. Beyonce's third solo album I Am... Sasha Fierce was inspired by Jay Z and especially by Etta James, whose "boldness" inspired Beyonce to explore other musical genres and styles. Her fourth solo album, 4, was inspired by Fela Kuti, 1990s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie with additional influences by The Jackson 5, New Edition, Adele, Florence and the Machine, and Prince.

A: paid homage to Baker

Q: Which of the following was never the name of a campus: Hilltop, Danforth or Olmsted?, Context: Washington University spent its first half century in downtown St. Louis bounded by Washington Ave., Lucas Place, and Locust Street. By the 1890s, owing to the dramatic expansion of the Manual School and a new benefactor in Robert Brookings, the University began to move west. The University Board of Directors began a process to find suitable ground and hired the landscape architecture firm Olmsted, Olmsted & Eliot of Boston. A committee of Robert S. Brookings, Henry Ware Eliot, and William Huse found a site of 103 acres (41.7 ha) just beyond Forest Park, located west of the city limits in St. Louis County. The elevation of the land was thought to resemble the Acropolis and inspired the nickname of "Hilltop" campus, renamed the Danforth campus in 2006 to honor former chancellor William H. Danforth.

A:
Olmsted
