Take the following as truth: Of the dozen villas that Tiberius built on Capri, his favorite island retreat, the best preserved is the ruins of Villa Jovis (Jupiter's Villa, or Tiberius' Villa), sprawling acrosean eastern promontory opposite the mainland.
Then the following statement: "Capri is Tiberius' favorite island retreat and he constructed a dozen villas on it." is true, false, or inconclusive?
