Final answer:
One of Lewis and Clark's tasks during their journey was Recording information about plant and animal life
Step-by-step explanation:
Lewis and Clark were tasked with meticulously documenting the flora and fauna encountered during their expedition. They meticulously cataloged species previously unknown to Western science, collecting samples and detailed descriptions. Their meticulous observations provided invaluable insights into the diverse ecosystems of the American West. Clark, in particular, possessed a keen interest in natural history, meticulously recording the new species they encountered. Both leaders understood the importance of these discoveries in expanding scientific knowledge about the continent.
Their journals contained detailed sketches and descriptions of plants, animals, and landscapes, which were later published and became vital resources for scientists and explorers. While they also engaged in mapping uncharted territories, their significant contribution to the understanding of North American biodiversity was through their comprehensive documentation of plant and animal life.
The correct answer is b) Recording information about plant and animal life.
