Take the following as truth: Designed in the late 13th century by Arnolfo di Cambio (architect of the Palazzo Vecchio and the Duomo) but with a neo-Gothic facade added in 1863, the Franciscan church of Santa Croce (east of the Uffizi) has an important series of Giotto frescoes.
Then the following statement: "Arnolfo di Cambio designed Santa Croce before he went to work on the Palazzo Vecchio and the Duomo." is true, false, or inconclusive?
Answer: Inconclusive
