Premise: Behind the alternating rocky and sandy coastline, from the marble quarries of Carrara, the mountain chain of the Apennines reaches south into Tuscany where lie the ageless beauties of Pisa, Lucca, Florence, and Siena, not to mention the smaller, and arguably more magical, hillside towns of Montepulciano, Volterra, and San Gimignano.

Hypothesis: They have no marble in Carrara.
Relation: contradiction
