select the word that best completes the sentence. manifest destiny referred to the choose... of the united states toward the pacific ocean. choose... expansive expansion expansively expansiveness

Explanation:

"Manifest Destiny" was about the territorial growth of the US. We need a noun to describe this growth. "Expansion" is a noun that fits the context as it refers to the act of increasing in size or territory. "Expansive" is an adjective, "expansively" is an adverb, and "expansiveness" is a more abstract - related noun but "expansion" is the most appropriate here for the context of territorial movement.

Answer:

expansion
