The answer to question 1:
C. They were laws created by Federalists to silence opposition and discourage immigration.
The Alien and Sedition Acts consisted of four laws passed in 1798. The laws restricted the activities of foreign residents in the country, allowed the government to deport foreigners and made it difficult for immigrants to vote, requiring them to reside for 14 years in the U.S. to become eligible to vote.
The Acts also limited freedom of speech and of the press, as an attempt to silence opposition to the Federalist's measures.
The answer to question 2:
C. Made because the United States was too weak to wage war.
By the time the conflict between France and Britain happened, at the beginning of 1793, the U.S.'s military army was too small and weak, and it decided not to risk.
