question: Crestwood is located in which greater metropolitan area?
answer: Greater St. Louis
context: Title: Greater Mexico City
  Passage: Greater Mexico City refers to the conurbation around Mexico City, officially called Valley of Mexico Metropolitan Area ("Zona Metropolitana del Valle de México"), constituted by Mexico City itself composed of 16 Municipalities—and 41 adjacent municipalities of the states of Mexico and Hidalgo.  For normative purposes, however, Greater Mexico City most commonly refers to the Metropolitan Area of the Valley of Mexico ("Zona Metropolitana del Valle de México") an agglomeration that incorporates 18 additional municipalities.  As of 2010 Census, Greater Mexico City had a population just over 20 million, making it the largest metropolitan area in North America just ahead of the New York metropolitan area.  But as of a 2014 census, it's estimated the population of Greater Mexico City was 25.4 million people, making it the largest urban agglomeration in the western hemisphere.  It is surrounded by thin strips of highlands which separate it from other adjacent metropolitan areas, of which the biggest are Puebla, Toluca, and Cuernavaca-Cuautla, and together with which it makes up the Mexico City megalopolis.

  Title: Narlıdere
  Passage: Narlıdere is a district of İzmir Province in Turkey.  It is one of the nine districts in the Greater Metropolitan Area of İzmir, one of the smallest in terms both of population and area, and is fully (100.0%) urbanized.  The district center has no depending township with own municipalities or villages.  Narlıdere district area follows the southern coastline of the inner Gulf of İzmir.  Narlıdere center is at a distance of 10 km to the west from the traditional center of İzmir (Konak).  Narlıdere district area neighbors the district areas of Balçova to the east, Menderes (Cumaovası) to the south and Güzelbahçe to the west, this last also being westernmost among İzmir's metropolitan districts.  Narlıdere district's overall levels of education are among the highest in Turkey, the literacy rate reaching 93 per cent, while the calculations for average yearly income per inhabitant situate Narlıdere rather below the national average, at 2.393 US Dollars, for which its open approach to outside immigration may have played a role.  The overall appearance of Narlıdere leaves the impression of a locality where people are generally educated and who subsist on mid- to low-level revenues without being destitute.  Narlıdere was founded as a village by semi-nomadic Tahtacı–Alevi Turkmens in the 18th century, whose descendants still constitute the backbone of the population, preserving their particular popular culture and folklore, and maintaining their recently restored seminary, called Cemevi.  The name the district has made as such contributes to its status as pole of attraction for various specific parts of the population in Turkey (its population is projected to have increased from 54.107 to 66.446 between 2000-2006).  The economy is still largely based on agriculture (especially citrus fruit and flowers), although new housing projects putting Narlıdere's advantageous location to benefit and generally aimed at high-income residents started to be built in recent years, and there is a five-star hotel.  As such, Narlıdere became in recent years one of İzmir's metropolitan districts where the economy grew the fastest.

Konak center is connected to other districts of İzmir and beyond by a dense network of roads and railroads, as well as by a subway line currently being largely extended and by ferry services to Karşıyaka.
