Take the following as truth: At the far (southern) end of the Mosque facing Mecca, toward which Muslims pray, you'll see pillars made of precious breccia and chalcedony; the stone-work in the mihrab (niche for prayers) is delicately carved.
Then the following statement: "The mosque took many years to build and was very expensive due to the intricacies." is true, false, or inconclusive?
Answer: Inconclusive
