Input: Read this: Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.
Question: What benefits does this serve?

Output: allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation


QUES: The mandolin has been used extensively in the traditional music of England and Scotland for generations. Simon Mayor is a prominent British player who has produced six solo albums, instructional books and DVDs, as well as recordings with his mandolin quartet the Mandolinquents. The instrument has also found its way into British rock music. The mandolin was played by Mike Oldfield (and introduced by Vivian Stanshall) on Oldfield's album Tubular Bells, as well as on a number of his subsequent albums (particularly prominently on Hergest Ridge (1974) and Ommadawn (1975)). It was used extensively by the British folk-rock band Lindisfarne, who featured two members on the instrument, Ray Jackson and Simon Cowe, and whose "Fog on the Tyne" was the biggest selling UK album of 1971-1972. The instrument was also used extensively in the UK folk revival of the 1960s and 1970s with bands such as Fairport Convention and Steeleye Span taking it on as the lead instrument in many of their songs. Maggie May by Rod Stewart, which hit No. 1 on both the British charts and the Billboard Hot 100, also featured Jackson's playing. It has also been used by other British rock musicians. Led Zeppelin's bassist John Paul Jones is an accomplished mandolin player and has recorded numerous songs on mandolin including Going to California and That's the Way; the mandolin part on The Battle of Evermore is played by Jimmy Page, who composed the song. Other Led Zeppelin songs featuring mandolin are Hey Hey What Can I Do, and Black Country Woman. Pete Townshend of The Who played mandolin on the track Mike Post Theme, along with many other tracks on Endless Wire. McGuinness Flint, for whom Graham Lyle played the mandolin on their most successful single, When I'm Dead And Gone, is another example. Lyle was also briefly a member of Ronnie Lane's Slim Chance, and played mandolin on their hit How Come. One of the more prominent early mandolin players in popular music was Robin Williamson in The Incredible String Band. Ian Anderson of Jethro Tull is a highly accomplished mandolin player (beautiful track Pussy Willow), as is his guitarist Martin Barre. The popular song Please Please Please Let Me Get What I Want by The Smiths featured a mandolin solo played by Johnny Marr. More recently, the Glasgow-based band Sons and Daughters featured the mandolin, played by Ailidh Lennon, on tracks such as Fight, Start to End, and Medicine. British folk-punk icons the Levellers also regularly use the mandolin in their songs. Current bands are also beginning to use the Mandolin and its unique sound - such as South London's Indigo Moss who use it throughout their recordings and live gigs. The mandolin has also featured in the playing of Matthew Bellamy in the rock band Muse. It also forms the basis of Paul McCartney's 2007 hit "Dance Tonight." That was not the first time a Beatle played a mandolin, however; that distinction goes to George Harrison on Gone Troppo, the title cut from the 1982 album of the same name. The mandolin is taught in Lanarkshire by the Lanarkshire Guitar and Mandolin Association to over 100 people. Also more recently hard rock supergroup Them Crooked Vultures have been playing a song based primarily using a mandolin. This song was left off their debut album, and features former Led Zeppelin bassist John Paul Jones.[citation needed]

QUES: During this early period, it was more usual that neither major party grouping (Federalists and Democratic-Republicans) had an official leader. In 1813, for instance, a scholar recounts that the Federalist minority of 36 Members needed a committee of 13 "to represent a party comprising a distinct minority" and "to coordinate the actions of men who were already partisans in the same cause." In 1828, a foreign observer of the House offered this perspective on the absence of formal party leadership on Capitol Hill:

There has been a football tournament at every Summer Olympic Games since 1900, except at the 1932 games in Los Angeles. Before the inception of the World Cup, the Olympics (especially during the 1920s) had the same status as the World Cup. Originally, the event was for amateurs only; however, since the 1984 Summer Olympics, professional players have been permitted, albeit with certain restrictions which prevent countries from fielding their strongest sides. The Olympic men's tournament is played at Under-23 level. In the past the Olympics have allowed a restricted number of over-age players per team. A women's tournament was added in 1996; in contrast to the men's event, full international sides without age restrictions play the women's Olympic tournament.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which year was there not a Summer Olympic Game?
Ah, so.. 1932


Question: During the summer growing season, phosphate is at a high level. It has a vital role in the breakdown of the sugars manufactured by chlorophyll. But in the fall, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem of the plant. When this happens, the sugar-breakdown process changes, leading to the production of anthocyanin pigments. The brighter the light during this period, the greater the production of anthocyanins and the more brilliant the resulting color display. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop.
Try to answer this question if possible: What causes sugar created by chlorophyll to breakdown?
Answer: phosphate


Question: Paper recycling processes can use either chemically or mechanically produced pulp; by mixing it with water and applying mechanical action the hydrogen bonds in the paper can be broken and fibres separated again. Most recycled paper contains a proportion of virgin fibre for the sake of quality; generally speaking, de-inked pulp is of the same quality or lower than the collected paper it was made from.
Try to answer this question if possible: What type of processes can only use mechanically produced pulp?
Answer:
unanswerable
