Question

how did advancements in medical technology influence imperialistic expansion? they led to significant population growth in imperial countries. they decreased the lifespan of individuals in colonized areas. they enabled imperial forces to survive in various colonized environments. they hindered expansion by reallocating finances away from key resources.

Explanation:

Advancements in medical technology in imperial countries allowed imperial forces to better survive in different environments they colonized, facilitating expansion. For example, treatments for tropical diseases enabled troops to operate in such regions. Population growth in imperial countries due to medical tech wasn't a direct link to expansion. Decreasing lifespan in colonized areas is incorrect as medical tech was not used to this end. And it didn't hinder expansion by re - allocating finances.

Answer:

They enabled imperial forces to survive in various colonized environments.
