Question: Alessandra Ferri was granted what most notable title for her profession?
Context: The La Scala Theatre Ballet (Italian: "Corpo di ballo del Teatro alla Scala" ) is the resident classical ballet company at La Scala in Milan, Italy.  One of the oldest and most renowned ballet companies in the world, the company predates the theatre, but was officially founded at the inauguration of La Scala in 1778.  Many leading dancers have performed with the company, including Mara Galeazzi, Alessandra Ferri, Viviana Durante, Roberto Bolle and Carla Fracci.  The official associate school of the company is the La Scala Theatre Ballet School (Italian: "Scuola di Ballo del Teatro alla Scala" ), a constituent of the La Scala Theatre Academy (Italian: "Accademia Teatro alla Scala" ). Modern urban planning in Canada can be traced back to the early 1900s, though Indigenous planning, an evolving practice, originated hundreds if not thousands of years ago.  The planning profession originally focused on city layout, land subdivision and architecture and grew dramatically after 1945 due to the growth of Canadian cities.  The profession now includes a diverse range of subjects such as urban sociology, data analysis and forecasting, municipal and planning law, management sciences and environmental sciences.  According to the Canadian Institute of Planners, the profession has grown from only 45 practicing planners in 1949 to about 7,000 practitioners in 2009.

To be recognised as a "prima ballerina assoluta" is a rare honour, traditionally reserved only for the most exceptional dancers of their generation.  Originally inspired by the Italian ballet masters of the early Romantic ballet, and literally meaning "absolute first ballerina", the title was bestowed on a prima ballerina who was considered to be exceptionally talented, above the standard of other leading ballerinas.  The title is very rarely used today and recent uses have typically been symbolic, either in recognition of a prestigious international career, or for exceptional service to a particular ballet company.  There is no universal procedure for designating who may receive the title, which has led to dispute in the ballet community over who can legitimately claim it.  It is usually a ballet company that bestows the title, however some dancers have had the title officially sanctioned by a government or head of state, sometimes for political rather than artistic reasons.  Less common is for a dancer to become identified as a "prima ballerina assoluta" as a result of public and critical opinion.
