input: Elizabeth's mother made an alliance with Lady Margaret Beaufort, mother of Henry Tudor, later King Henry VII, who had the closest claim to the throne of those in the Lancastrian party. Although Henry Tudor was descended from King Edward III, his claim to the throne was weak, due to an act of parliament passed during the reign of Richard II in the 1390s, that barred accession to the throne to any heirs of the legitimised offspring of Henry's great-great-grandparents, John of Gaunt and Katherine Swynford. Despite this, his mother and Elizabeth Woodville agreed Henry should move to claim the throne and, once he had taken it, marry Elizabeth of York to unite the two rival houses. In December 1483, in the cathedral in Rennes, Henry Tudor swore an oath promising to marry her and began planning an invasion.  In 1484, Elizabeth of York and her sisters left Westminster Abbey and returned to court when Elizabeth Woodville was reconciled with Richard III, which may suggest that Elizabeth Woodville believed Richard III to be innocent of any possible role in the murder of her two sons (although this is unlikely owing to her involvement in Henry Tudor's failed invasion of October 1483). It was rumoured that Richard III intended to marry Elizabeth of York because his wife, Anne Neville, was dying and they had no surviving children. The Crowland Chronicle claimed that Richard III was forced to deny this unsavoury rumour. Soon after Anne Neville's death, Richard III sent Elizabeth away from court to the castle of Sheriff Hutton and opened negotiations with King John II of Portugal to marry his sister, Joan, Princess of Portugal, and to have Elizabeth marry their cousin, the future King Manuel I of Portugal.  On 7 August 1485, Henry Tudor and his army landed in Wales and began marching inland. On 22 August 1485, Henry Tudor and Richard III fought the Battle of Bosworth Field. Richard III, despite having the larger army, was betrayed by one of his most powerful retainers, William Stanley, and died in battle. Henry Tudor took the crown by right of conquest as Henry VII.

input: Khan's central innovation in skyscraper design and construction was the idea of the "tube" structural system for tall buildings, including the framed tube, trussed tube, and bundled tube variants. His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design. Most buildings over 40 stories constructed since the 1960s now use a tube design derived from Khan's structural engineering principles.  Lateral loads (horizontal forces) such as wind forces, seismic forces, etc., begin to dominate the structural system and take on increasing importance in the overall building system as the building height increases. Wind forces become very substantial, and forces caused by earthquakes, etc. are important as well. The tubular designs resist such forces for tall buildings. Tube structures are stiff and have significant advantages over other framing systems. They not only make the buildings structurally stronger and more efficient, but also significantly reduce the structural material requirements. The reduction of material makes the buildings economically more efficient and reduces environmental impact. The tubular designs enable buildings to reach even greater heights. Tubular systems allow greater interior space and further enable buildings to take on various shapes, offering added freedom to architects. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Khan was among a group of engineers who encouraged a rebirth in skyscraper construction after a hiatus of over thirty years.  The tubular systems have yet to reach their limit when it comes to height. Another important feature of the tubular systems is that buildings can be constructed using steel or reinforced concrete, or a composite of the two, to reach greater heights. Khan pioneered the use of lightweight concrete for high-rise buildings, at a time when reinforced concrete was used for mostly low-rise construction of only a few stories in height. Most of Khan's designs were conceived considering pre-fabrication and repetition of components so projects could be quickly built with minimal errors.  The population explosion, starting with the baby boom of the 1950s, created widespread concern about the amount of available living space, which Khan solved by building upward. More than any other 20th-century engineer, Fazlur Rahman Khan made it possible for people to live and work in "cities in the sky." Mark Sarkisian (Director of Structural and Seismic Engineering at Skidmore, Owings & Merrill) said, "Khan was a visionary who transformed skyscrapers into sky cities while staying firmly grounded in the fundamentals of engineering."

Answer this question "Does this design help when there is a fire in a building?"
output: systems. They not only make the buildings structurally stronger

input: In 1929, he became a member of Eva Le Gallienne's Civic Repertory Theatre company in New York City. Although best known to the larger world audience for his film and television work, Meredith was an influential actor and director for the stage. He made his Broadway debut as Peter in Le Gallienne's production of Romeo and Juliet (1930) and became a star in Maxwell Anderson's Winterset (1935), which became his film debut the following year. His early life and theatre work were the subject of a New Yorker profile.  He garnered critical acclaim in the 1935 Broadway revival of The Barretts of Wimpole Street starring Katharine Cornell. She subsequently cast him in several of her later productions. Other Broadway roles included Van van Dorn in High Tor (1937), Liliom in Liliom (1940), Christy Mahon in The Playboy of the Western World (1946), and Adolphus Cusins Major Barbara (1957). He created the role of Erie Smith in the English-language premiere of Eugene O'Neill's Hughie at the Theater Royal in Bath, England in 1963. He played Hamlet in avant garde theatrical and radio productions of the play.  A distinguished theatre director, he won a Tony Award nomination for his 1974 Broadway staging of Ulysses in Nighttown, a theatrical adaptation of the "Nighttown" section of James Joyce's Ulysses. Meredith also shared a Special Tony Award with James Thurber for their collaboration on A Thurber Carnival (1960). In the late seventies, he directed Fionnula Flanagan's one-woman multi-role play "James Joyce's Women," which toured for several years.
