Take the following as truth: 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).
Then the following statement: "Hundreds of replicas have been made of Jacopo della Quercia's original carvings." is true, false, or inconclusive?
Answer: Inconclusive
