To determine the estimated percentage of the Native American population that died in the wake of the Spanish voyages, we need to consider historical estimates and evidence provided by researchers.
Based on these estimates, it is understood that the percentage of the Native American population that died ranges between:
- A lower bound of 50%
- An upper bound of 90%
Therefore, looking at the provided options:
1. 10-30%: This range is too low considering the historical evidence.
2. 30-50%: This range is also lower than the historical estimates.
3. 50-70%: While this range captures the lower bound (50%), it does not capture the upper bound (90%).
4. 50-90%: This is the correct range that aligns with the historical estimates of 50% to 90%.
Thus, the estimated percentage of the Native American population that died in the wake of the Spanish voyages is:
50-90%
