Answer:
Opportunities - Employment equality, equal rights
Challenges - returning men would demand their jobs back
Explanation:
The World War II saw many men going to fight in the wars in different countries. This meant that all able-bodied men were either recruited or conscripted into the army. Thus, many men left, leaving behind children and women. Thus, there was a need to keep production going in the home countries. In the UK, for example, women worked in factories. Some even took up clerical jobs. Some repaired airplanes, some worked as communication officers and photograph analyzers. This gave women a platform for equality.
Unfortunately, this was to end with the return of the men who had gone to fight in the war. However, women had made a mark for themselves in the arena.
The United States tried to remain neutral during World War I, but numerous things occured that tipped the balance and made the U.S. finally declare war. The first thing was the sinking of the Lusitania in 1915, by Germany. The Lusitania was a ship carrying over 1,000 innocent passengers, with over 100 Americans onboard, a German U-boat sank the ship, ultimately killing everyone. Americans were furious about this, but it was not enough for the United States to declare war and join the Allied powers during World War I. The Zimmerman Telegram was the occurrence that finally made President Woodrow Wilson finally declare war. The Zimmerman Telegram was supposed to be a secret telegram to Mexico from the Germans, however it was decoded and brought to the United States' attention in 1917. This telegram stated if Mexico sided with Germany during World War I, and attacked the states, when Germany won the war they promised they would give Mexico territories. This was a huge threat, as Mexico bordered the United States, and it was the final straw into the United States entering World War I. On April 6, 1917, after the speech of Woodrow Wilson, the United States had officially declared war on Germany and entered World War I as one of the Allied powers.
I know that manifest destiny was the mindset of Americans that they were destined to stretch from coast to coast.
The Louisiana purchase was during that time. Napoleon didn't have the troops to keep Louisiana so he sold it to us for cheap.
World War 1 because as Taskmasters said on this website, "Dadaism was an art movement of the European avant-garde, in the early 20th century, which was heavily influenced by World War I. It was anti-war and anti-bourgeois, and had political affinities with radical left. Some of the key figures of the Dada movement were: Hugo Ball, Emmy Hennings, Hans Arp, George Grosz, Max Ernst, Beatrice Wood, Tristan Tzara, Francis Picabia, etc. The movement influenced later styles in art such as Surrealism, Nouveau Realisme, pop art and Fluxus."
