context: Title: 1975 Boston Red Sox season

Following a sweep of the Oakland Athletics in the ALCS, the Red Sox lost the World Series to the Cincinnati Reds in seven games.  In their 4 losses in the World Series, they had a lead at one point in the game, only to let the Reds come back and win all 4, spoiling the Sox's chances at winning the World Series for the first time since 1918, which would've ended the Curse of the Bambino.  In game 7, the Red Sox had a 3-0 lead at one point, but the Reds rallied back to spoil the Red Sox chances of a major upset.

  Title: Mayor of Rome
  Passage: The Mayor of Rome (Italian: "Sindaco di Roma Capitale" ) is an elected politician who, along with Rome’s City Council (Italian: "Assemblea Capitolina" ) of 48 members, is accountable for the strategic government of Rome.  As Rome is a "comune speciale" since 2009, the office is different from the offices of the other Italian cities.

  Title: R. Cowles Taylor
  Passage: Robert Cowles Taylor (August 12, 1893 – December 20, 1955) was the mayor of Newport News, Virginia from 1942 to 1955.  As such, he was mayor of the city during World War II, at a time when the city's ports were used to send American troops to Europe to fight in the war.  As was seen during World War I, this activity put a tremendous strain on the city's infrastructure, and Taylor was instrumental in seeing that the city continued to function despite the effort.  At one point, several tens of thousand of homes, rooms and hotels would come under rent control imposed by Taylor.  Taylor also held the dubious honor of being the only casualty of the celebrations that followed the end of the war - his car was stolen during a meeting of the Rotary Club.

  Title: Point process operation
  Passage: In probability and statistics, a point process operation or point process transformation is a type of mathematical operation performed on a random object known as a point process, which are often used as mathematical models of phenomena that can be represented as points randomly located in space.  These operations can be purely random, deterministic or both, and are used to construct new point processes, which can be then also used as mathematical models.  The operations may include removing or "thinning" points from a point process, combining or "superimposing" multiple point processes into one point process or transforming the underlying space of the point process into another space.  Point process operations and the resulting point processes are used in the theory of point processes and related fields such as stochastic geometry and spatial statistics.
  Title: Reno Air

  Title: Tirrenia Studios
  Passage: The Tirrenia Studios (also known at one point as the Pisorno Studios) are a film studio complex located in the Italian coastal town of Tirrenia in Tuscany.  The studios were constructed between 1933-1934 and intended, along with the Fert Studios in Turin, to provide northern competition to the increasingly dominant Cines Studios in Rome.  Tirrenia was a new town which had grown with the support of Italy's Fascist regime.  Although Italian film production was booming following an early 1930s slump, Tirrenia quickly faced increasing competition from the large Cinecitta studios in Rome which had been opened in 1937 as part of the Fascist's attempt to centralise film production in the capital.  Nonetheless the studios continued to be used, sometimes facilitating location shooting nearby.
