Take the following as truth: It boasts a fine south porch and marble and alabaster treasures that evoke the wealth of the diocese in the 16th and 17th centuries, particularly the elaborate chapel screens and, in the northern arm of the transept, an intricate 16th-century astronomical clock.
Then the following statement: "Nobody knows exactly how much the diocese was worth during the 16th and 17th centuries." is true, false, or inconclusive?
Answer: Inconclusive
