Text: A second floor loggia is adorned with Jacopo della Quercia's 15th-century carvings for the city fountain Fonte Gaia (of which a poor 19th-century replica stands in the piazza).
Entailment: Jacopo della Quercia's 15th-century carvings are displayed in the second floor loggia.
Contradiction: The second floor loggia features no carvings and is really very plain.
