Answer:
The phrase and the pause enable Roosevelt to emphasize the emotional impact of this tragic loss of life.
Step-by-step explanation:
A moment of silence is a short period of silence that represents a gesture of respect to those who have died recently or as a part of a tragic historical event. It may be conducted following the tragedy or on its anniversary. This is what the pause in Infamy Speech, delivered by Roosevelt on December 8, 1841, the day following Japan's attack on Pearl Harbor, represents. By doing this, he expressed his condolences in a brief respectful way, just like commanders usually do following a tragedy during the war.
