Which motivation for exploring the Pacific Northwest did Spain, Russia, America, and Britain have in common? to establish a fur trade
to find gold and silver
to spread Christianity
to expand their influence

Explanation:

In the century between the 1740s and the 1840s, different nations competed with one another, and with native peoples, to take control over the area that is today known as the American Pacific Northwest and the west coast of Canada. In one sense this competition had begun in 1492, when Columbus landed in the New World, claimed it for Spain, and inaugurated a European rivalry for territory. Over the next two years, the Pope responded to the discovery and the threat of competition over it essentially by dividing the western hemisphere into Spanish and Portuguese zones of influence, and assigning the Pacific Northwest to Spain. Yet Europeans would not actually see Alaska and the Pacific Northwest until the 18th century, when their ambitions spurred one another to explore the territory. The contest ended in 1846, when the Americans and British divided most of the region between themselves by drawing a boundary between Canada and the United States at the 49th parallel; another key event occurred when Russia sold Alaska to the United States in 1867. It thus took more than three and a half centuries for peoples of European descent, following up on Columbus’s first voyage, to establish some degree of mutually respected authority over the Pacific Northwest (and for decades longer, even that authority remained contested by native peoples). This long span of time illustrates just how isolated the region once was from European centers of power.

while it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton.

explanation:

before eli whitney's invention of the cotton gin, picking and cleaning cotton was a slow, labor-intensive job. workers, usually slaves, had to pick the seeds from the cotton fibers by hand. this invention made it possible to grow large amounts of cotton on big farms and make money.
