Final answer:
The claim concerning obsidian trade and Jarmo is false; it was actually Catal Huyuk that was renowned for its obsidian trade, contributing to long-distance trade networks.
Step-by-step explanation:
The statement that 'Obsidian was a large trade for Jarmo' is false. The correct information is that it was Catal Huyuk, not Jarmo, which was famous for its trade in obsidian. Catal Huyuk was built on a site rich in obsidian, which allowed them to produce sharp tools and weapons.
This enabled Catal Huyuk to participate in long-distance trade networks, exchanging obsidian for other goods. The evidence of obsidian tools from Catal Huyuk found hundreds of miles away from the site demonstrates the extensive trade networks of the time and the specialization in manufacturing.
