Question

What is a main argument of "The Corps of Discovery Expedition?"


Because they are expensive, journeys of exploration should have multiple purposes to be worth doing.


Lewis and Clark's journey was considered a successful claim of Western land by the US government.


Lewis and Clark's observations of Western plants and animals led to increased interest in scientific observation throughout the US.

Answer 1

Because they are expensive, journeys of exploration should have multiple purposes to be worth doing.

The passage emphasizes that Lewis and Clark's expedition pursued scientific, political, and economic goals (mapping, natural history, claiming territory, diplomacy), showing that costly explorations need several aims to justify them.
