Read the following text, taken from a speech by President Franklin Delano Roosevelt.
“As Commander in Chief of the Army and Navy, I have directed that all measures be taken for our defense. But always will our whole nation remember the character of the onslaught against us.
No matter how long it may take us to overcome this premeditated invasion, the American people in their righteous might will win through to absolute victory.
I believe that I interpret the will of the Congress and of the people when I assert that we will not only defend ourselves to the uttermost, but will make it very certain that this form of treachery shall never again endanger us.
Hostilities exist. There is no blinking at the fact that our people, our territory, and our interests are in grave danger.
With confidence in our armed forces, with the unbounding determination of our people, we will gain the inevitable triumph—so help us God.
I ask that Congress declare that since the unprovoked and dastardly attack by Japan on Sunday, December 7th, 1941, a state of war has existed between the United States and the Japanese empire. “
Based on the excerpt, what event was Roosevelt addressing when he made this speech?
The date of December 7, 1941, is located within the speech, so this should help you identify the event as the attack on Pearl Harbor, (B). Since the president is addressing Japanese aggression on U.S. territory, you can eliminate the other options.
