Final answer:
The statement that European conquerors with superior weaponry led to the majority of native deaths in the exploration period is true. However, diseases like smallpox were the predominant cause of the decline in the Indigenous population due to their lack of immunity.
Step-by-step explanation:
The statement that the majority of the natives killed in the exploration period were slaughtered by the Europeans who possessed superior weapons is true. During the period of European exploration and colonization, Indigenous populations suffered greatly due to a combination of factors. These included not only armed conflicts where Europeans had an advantage through superior weaponry but also the introduction of new diseases to which natives had no immunity, enslavement, and other forms of oppression. Although warfare certainly led to many deaths, the spread of diseases like smallpox was responsible for the vast majority of the native population's decline. The lack of genetic immunity among the Indigenous people to such illnesses resulted in higher mortality rates than the actual combat against European conquerors.
