"WWII ends"

Would this be considered a movement,trend, or activities in literature, science, art or economics...anyone of these?

It would be considered an event.

We could consider the end of WWII an activity in economics. Instead of spending immense amounts of money on the war effort, the countries now had this money to spend upon rebuilding their societies. Consumer goods, such as refrigerators, cars, and steel for road building could now be manufactured since these factories weren't needed for making guns and military vehicles.

To a much lesser extent, the end of WWII could also be considered an activity in literature, science, and art.

Thank you again! I wasn't sure if the end of WWII would be considered as any of those activities...

You're welcome.

Please check to see if "event," as suggested by GuruBlue, is the same as "activity."

"WWII ends" would be considered as an historical event. It is not specifically related to a movement, trend, or activities in literature, science, art, or economics. Instead, it refers to the conclusion of World War II, a significant event in world history. To understand and study historical events, it is important to consult historical books, articles, and sources that provide information on key events and their impact on different aspects of society. By examining primary and secondary sources, historians analyze the causes, progression, and consequences of events like the end of WWII.
