Final answer:
Manifest Destiny led to the forceful acquisition of land and removal of Native Americans and Hispanic communities from their territories. The Democratic-Republicans opposed the Alien and Sedition Acts because they viewed them as unconstitutional.
Step-by-step explanation:
Manifest Destiny's Impact on Native Americans and Hispanic Communities:
The philosophy of Manifest Destiny deeply affected the lives of Native Americans and Hispanic communities living in new U.S. territories. As Americans moved westward in the 19th century, driven by the belief in their manifest destiny to expand across the continent, the existing inhabitants faced profound consequences. The correct answer to how Manifest Destiny affected these communities is:
A. They could have their lands taken and be removed from the area.
Opposition to the Alien and Sedition Acts:
The Democratic-Republicans opposed the Alien and Sedition Acts primarily because they believed the acts were unconstitutional. These laws, passed in 1798, were seen as limiting freedom of speech and the press, and as a result, encroaching upon the rights protected under the Constitution. The correct answer to the reason given by the Democratic-Republicans for opposing the acts is:
A. They were unconstitutional.
