Answer 1

"The United States had refused to sell oil and scrap metal to Japan."

Explanation: U.S. embargoes and freezing of Japanese assets in 1940–41 cut off vital oil and raw materials Japan needed for its military and economy. Facing resource starvation and choosing to secure supplies in Southeast Asia while attempting to neutralize the U.S. Pacific Fleet, Japan planned the surprise attack on Pearl Harbor. The other options are incorrect or out of sequence (e.g., the U.S. did not declare war on Germany until after Pearl Harbor).
