Take the following as truth: Tucked behind Rua Joao Tavira and Rua da Carreira is Praca do Munic?­pio, the town's dignified main square, with a mosaic of black-and-white stones and pretty white buildings on three sides.
Then the following statement: "There are pretty white buildings situated in the town square but there are no black and white stones." is true, false, or inconclusive?
