Take the following as truth: Up to 20,000 Nabateans may have once lived here, but earthquakes in the fourth and eighth centuries destroyed most of the city; what remain today are only the sturdiest, most monumental tombs and temples.
Then the following statement: "Some people tried to rebuild the city after the earthquake in the fourth century, but after the second one in the eighth century, they all left." is true, false, or inconclusive?
Answer: Inconclusive
