Take the following as truth: Around Jalan d'Albuquerque and Dataran Portugis (Portuguese Square), the houses look no different from those in the rest of Melaka, but you may hear snatches of Cristao, a 16th-century Portuguese dialect, and mothers calling out to Afonso, Luis, or Filomena. 
Then the following statement: "The homes around Portuguese Square are occupied only by people who speak Cristao." is true, false, or inconclusive?
Answer: Inconclusive
