The attack on Pearl Harbor on December 7, 1941 led the United States to enter World War II.

• A. Cannot be determined
• B. Partially true
• C. True
• D. False

Answer: (C)

A direct act of aggression that provokes a formal response can shift a country from neutrality to active participation in a war. The attack on Pearl Harbor was a surprise strike against the U.S. Pacific Fleet on December 7, 1941. In response, the United States declared war on Japan the next day, officially entering World War II, and soon after Germany and Italy declared war on the United States. Because the statement describes Pearl Harbor as the event that led the United States to enter World War II, it is true. The other options don’t fit, since the historical outcome is clear and not a matter of uncertainty, partial truth, or falsehood.
