Question

what was a consequence of teotihuacan excavation and trade of obsidian?
teotihuacan learned more about volcanic rocks than other mesoamerican civilizations
teotihuacan developed more advanced fishing than other mesoamerican civilizations
teotihuacan merchants became the leaders of their civilization’s region
teotihuacan gained wealth and power that fueled the urban development

Explanation:

To determine the consequence of Teotihuacan's excavation and trade of obsidian, we analyze each option:

• Option 1: Learning more about volcanic rocks (obsidian is volcanic glass) through excavation makes sense as studying the resource would increase knowledge. But we need to check other options.
• Option 2: Teotihuacan was not known for advanced fishing; Mesoamerican civilizations like those near coasts focused on fishing, so this is incorrect.
• Option 3: There's no evidence Teotihuacan merchants became regional leaders due to obsidian trade; leadership structures were different.
• Option 4: Trade of obsidian (a valuable resource) would bring wealth and power, fueling urban development. This aligns with how trade in valuable goods boosts civilizations. Between option 1 and 4, option 4 is a direct consequence of trade (wealth from trade) while option 1 is about excavation - related knowledge. Since the question is about excavation AND trade, the economic impact (wealth for urban development) is a key consequence.

Answer:

D. Teotihuacan gained wealth and power that fueled the urban development (assuming the last option is D; if the options are labeled as per the order: the fourth option "Teotihuacan gained wealth and power that fueled the urban development" is the correct answer. If the options are A - D with A as first, D as fourth, then D. Teotihuacan gained wealth and power that fueled the urban development)
