I want to know the answer to the following question:
What does Archibald Sayce think early Sumerian pictograms suggest about the availability of stone?
All the background I'm provided with is that "According to Archibald Sayce, the primitive pictograms of the early Sumerian (i.e. Uruk) era suggest that "Stone was scarce, but was already cut into blocks and seals.". Is that enough to answer the question?
Answer: yes
