To best complete the thinking map, the selection of options would depend on the context of the map you are working with. Without further context regarding what the thinking map is about, it’s challenging to provide the most accurate answer. However, if we're discussing topics related to the Columbian Exchange or the impact of European colonization, the relevant options might be:
- Smallpox: This represents a disease brought from Europe to the Americas, having a significant impact on indigenous populations.
- Cattle: These were introduced to the Americas as part of agricultural expansion and the Columbian Exchange.
On the other hand, if the thinking map relates to valuable trade goods, both Tobacco and Cacao could also apply as they were significant cash crops cultivated and exported from the Americas.
Without a specific prompt or theme for the thinking map, the best answer could potentially include all four options depending on what is being categorized. Please provide more context if possible!
