  sentences:
  - 'Mythology in France epics and fairy tales as part of deeply embedded spiritual
    allegories and mythological archetypes: Mythology in France The mythologies in
    present-day France encompass the mythology of the Gauls, Franks, Normans, Bretons,
    and other peoples living in France, those ancient stories about divine or heroic
    beings that these particular cultures believed to be true and that often use supernatural
    events or characters to explain the nature of the universe and humanity. French
    mythology is listed for each culture. Bretons are a subset of the celtics that
    adopted Christianity. Celtic cosmology predominates their mythology: Gauls were
    another subset of Celtic people. Celtic'
  - Johnny Depp in a snuff film in exchange for money for his family. Depp was a fan
    and friend of writer Hunter S. Thompson, and played his alter ego Raoul Duke in
    "Fear and Loathing in Las Vegas" (1998), Terry Gilliam's film adaptation of Thompson's
    pseudobiographical novel of the same name. Depp's next venture with Burton was
    the period film "Sleepy Hollow" (1999), in which he played Ichabod Crane opposite
    Christina Ricci and Christopher Walken. For his performance, Depp took inspiration
    from Angela Lansbury, Roddy McDowall and Basil Rathbone. He stated that he "always
    thought of Ichabod as a very delicate, fragile
  - Ichabod Crane Kinderhook town school district (Ichabod Crane Central School District)
    is also named for the Irving character. It is claimed by many in Tarrytown that
    Samuel Youngs is the original from whom Irving drew his character of Ichabod Crane".
    Author Gary Denis asserts that while the character of Ichabod Crane is loosely
    based on Kinderhook Schoolmaster, Jesse Merwin, it may possibly include elements
    from Samuel Youngs' life. Irving's characters drive the story and are most memorable
    because of his detail in describing each. He says of Ichabod Crane (the main character),

    in the UK. On "Different Gear, Still Speeding", all members contributed to the
    instrumentation, much like the later albums of Oasis. Reviews of the album have
    been generally mixed-to-favourable. According to review aggregator site Metacritic,
    the album has an average score of 65%. Reviewing for "Rolling Stone", Stacey Anderson,

  - Mickey Mouse universe was originally going to be named Mortimer. Lillian Disney,
    Walt's wife, suggested the name Mickey instead. The first Mortimer was created
    by Walt Disney and Floyd Gottfredson for the comics. He was Minnie Mouse's ranch-owning
    cattleman uncle. He first appeared in the serial "Mickey Mouse in Death Valley"
    (1930). After that, he appeared or was referenced in many other Mickey Mouse comic
    strip adventures in the 1930s. He has occasionally appeared in more modern comics.
    In the 1936 cartoon short "Mickey's Rival", the second Mortimer was introduced
    as Mickey's competitor for Minnie's affections. In the comics, this Mortimer was

  - Different Gear, Still Speeding gave the album 2.5 out of 5 stars, said "On Different
    Gear, the band attempts stripped down, Stones-y rock but ends up with 'Be Here
    Now'-style guitar bluster and Liam's blithely boilerplate lyrics". Drowned in
    Sound awarded the album 4/10 saying that "By and large it radiates the stolid
    competence of a band on auto-pilot, with a few flashes of likeable enthusiasm."
    The "Independent on Sunday" gave it 2/5 stars. Simon Goddard, reviewing for "Q",
    gave the album four-out-of-five stars and described it as "the strongest record
    Liam's made" since "(What's the Story) Morning Glory?", while Garry Mulholland,

    variations: E&M defines eight wires: "4-wire E&M" uses a 4-wire (2-pair) transmission
    path for the voice signal. "2-wire E&M" uses a single pair for both transmit and
    receive voice signal. This is much inferior to 4-wire E&M as the 2-wire interface
    uses hybrid transformers which reduce signal quality and can introduce echo. The

    – to be signaled. In order to allow dialing over'

    the late 1970s. Notable bands from Athens include R.E.M., The B-52's, Widespread
    Panic, Drive-By Truckers, as well as bands from the Elephant 6 Recording Company
    most notably Neutral Milk Hotel. Rhythm and Blues is another important musical
    genre in Georgia. Ray Charles was one of popular music's most influential performers,
    fusing R&B, jazz, and country into many popular songs. Augusta native James Brown

    was murdered by Mark David Chapman in front of The Dakota in New York City. It

  - Three Men in a Boat Three Men in a Boat Three Men in a Boat (To Say Nothing of
    the Dog), published in 1889, is a humorous account by English writer Jerome K.
    Jerome of a two-week boating holiday on the Thames from Kingston upon Thames to
    Oxford and back to Kingston. The book was initially intended to be a serious travel
    guide, with accounts of local history along the route, but the humorous elements
    took over to the point where the serious and somewhat sentimental passages seem
    a distraction to the comic novel. One of the most praised things about "Three

    to raise the spirits of one of them, who is about to be expelled from university.
    To take the place of Montmorency, they bring a cat called Tintoretto. Three Men

- source_sentence: In the RAF, what is the rank immediately above Squadron Leader?
  sentences:
  - Tybalt Tybalt Tybalt is the main antagonist in William Shakespeare's play "Romeo
    and Juliet". He is the son of Lady Capulet's brother, Juliet's short-tempered
    first cousin, and Romeo's rival. Tybalt shares the same name as the character
    Tibert/Tybalt the "Prince of Cats" in "Reynard the Fox", a point of mockery in
    the play. Mercutio repeatedly calls Tybalt "Prince of Cats" (perhaps referring
    not only to Reynard but to the Italian word cazzo as well). Luigi da Porto adapted
    the story as "Giulietta e Romeo" and included it in his "Historia novellamente
    ritrovata di due Nobili Amanti" published in 1530. Da Porto
  - Squadron leader RAF used major as the equivalent rank to squadron leader. Royal
    Naval Air Service lieutenant-commanders and Royal Flying Corps majors on 31 March
    1918 became RAF majors on 1 April 1918. On 31 August 1919, the RAF rank of major
    was superseded by squadron leader which has remained in continuous usage ever
    since. Promotion to squadron leader is strictly on merit, and requires the individual
    to be appointed to a Career Commission, which will see them remain in the RAF
    until retirement or voluntary resignation. Before the Second World War, a squadron
    leader commanded a squadron of aircraft. Today, however,
  - Squadron leader Squadron leader Squadron leader (Sqn Ldr in the RAF ; SQNLDR in
    the RAAF and RNZAF; formerly sometimes S/L in all services) is a commissioned
    rank in the Royal Air Force and the air forces of many countries which have historical
    British influence. It is also sometimes used as the English translation of an
    equivalent rank in countries which have a non-English air force-specific rank
    structure. An air force squadron leader ranks above flight lieutenant and immediately
    below wing commander and it is the most junior of the senior officer ranks. The
    air force rank of squadron leader has a

The terms "keg" and "cask" refer to containers of any size, the distinction being that kegs are used for beers intended</code>                                                                                            | <code>Beer Barrel Polecats Percy Pomeroy (Eddie Laughton), and work together to flee the prison. They are ultimately captured, and sent to solitary confinement. After nearly half a century later, the graying trio are finally released as senior citizens, in which Curly quips upon leaving "You know what I'm-a gonna do? I'm gonna get myself a tall, big, beautiful bottle of beer!" Moe and Larry become irate and throw Curly back into the jail, leaving him there. The title "Beer Barrel Polecats" is a pun of the song "Beer Barrel Polka". The idea of producing and selling their own beer during Prohibition was borrowed</code>                                                                                   |
