Final answer:
President Roosevelt learned the details about the Pearl Harbor attack shortly after it occurred. The speed of news reporting and information in 1941 was much slower compared to today's instant access through technology and social media.
Step-by-step explanation:
President Roosevelt learned the details about the Pearl Harbor attack shortly after it occurred. The attack began on December 7, 1941, and by December 8, Roosevelt addressed Congress and asked for a declaration of war against Japan. The news of the attack spread quickly through various channels at the time, including newspapers, radio, and telegrams.
Comparing the speed of news reporting and information in 1941 to today, there have been significant advancements in technology and communication. In 1941, news traveled through traditional media outlets and communication methods, which could take several hours or even days to reach the public.
Today, with the advent of the internet and social media, news spreads instantly, and people can access information within seconds of an event occurring.
