Take the following as truth: Beside the Piazza Venezia, a steep staircase leads up to the austere 13th-century Santa Maria in Aracoeli, while another, more graceful and gradual, takes you up between the statues of Castor and Pollux to Michelangelo's beautifully proportioned square of the Campidoglio (Capitoline Hill).
Then the following statement: "The statues of Castor and Pollux have been up for over 1,000 years." is true, false, or inconclusive?
Answer: Inconclusive
