Final answer:
The assertion that all European countries opted for white indentured servants over African slaves in the New World is false. External factors and perceived advantages of enslaving Africans led to the preference for slavery to meet labor demands in the colonies.
Step-by-step explanation:
The statement 'All European countries tried to use white indentured servants instead of opting for black slaves for labor in the new world' is false. While European indentured servants were utilized to some extent, factors such as the harsh Caribbean climate, diseases like malaria and yellow fever, high European death rates, and legal limitations on the treatment of indentured servants made this form of labor inefficient and inadequate for the needs of colonial plantations. In contrast, Africans were believed to be more physically suited for hard labor and could be enslaved for life, providing a more reliable and permanent labor source.
Furthermore, the creation of legal and racial distinctions between Europeans and Africans facilitated the transition to a labor system built on slavery and racism. Therefore, it is evident that not all European countries solely relied on indentured servants; slavery became the preferred method to meet labor demands.
