Question: What city was the author of The Dream of Rome at one point the mayor of?
Context: The Dream Of Rome (2006) is a book by Boris Johnson, in which he discusses how the Roman Empire achieved political and cultural unity in Europe, and compares it to the failure of the European Union to do the same.  It was aired as a BBC television documentary prior to its release as a book. 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.  The title is the equivalent of Lord Mayor in the meaning of an actual executive leader. Reno Air was a scheduled passenger airline headquartered in Reno, Nevada, United States.  Reno Air provided service from its hubs at Reno/Tahoe International Airport in Reno, Nevada, San Jose International Airport in San Jose, California and Las Vegas International Airport in Las Vegas, Nevada to destinations throughout the western United States, including Alaska.  International service to Vancouver, British Columbia in western Canada was also served at one point and limited service was operated to the midwestern U.S. as well.  A small stand alone operation was also undertaken at one point in the southeastern U.S. with the service being based in Gulfport, Mississippi.  Reno Air was acquired by American Airlines in 1999. The 1975 Boston Red Sox season was the 75th season in the franchise's Major League Baseball history.  The Red Sox finished first in the American League East with a record of 95 wins and 65 losses.  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.

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. 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.

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. Caraceni was founded in Rome in 1913 by the father of Italian tailoring, Domenico Caraceni.  At one point in the 1930s, Domenico and his family operated ateliers in Rome, Milan and Paris.
