Take the following as truth: You get a sense of the dukes' grandeur among the Renaissance palazzi of the Corso Ercole I d'Este, part of a 15th-century urban expansion, Addizione Erculea, that was one of the most ambitious pieces of town planning of its age.
Then the following statement: "There was also an ambitious example town planning there in the 16th century." is true, false, or inconclusive?
