I'm pretty positive that it would be personification.
The power to collect taxes was denied to tge federal government.
Both western europeans and latin american people could immigrate "freely" under that immigration act. The act was intended as a mean to limit the immigration of people whose ancestry was "non white", while increasing the number of "white" inmigrants to guarantee a more homogeneous population in the US. The first group of people was allowed to immigrate because many people living in the US came from the british islands, and in the case of latin american people, since they were a mixture of european and native american parents, they were considered as "white", too. People not allowed to immigrate under this act: asians and east europeans.
In August 1805 Lewis and Clark were looking for the Shoshone Indians. The Corps (Lewis and Clark's expedition party) needed horses to cross the Rockies and the Shoshone had them. Sacagawea, a member of the Corps, was Shoshone, but she had been kidnapped by another tribe many years before.
The Corps were still recovering from their portage around the Great Falls of Missouri. Morale was low. Lewis and three men were scouting ahead when they finally met a band of Shoshone. They were the first white men the Shoshone had ever seen.
hope this helps in anyway! :)
