From what it sounds like, "concealed propaganda", would be propaganda that is subtle, trying to slowly edge under the skin of a reader, in order to make it seem like it fits in normal life. They sound familiar to news you would hear otherwise. "Revealed propaganda", would seem like it's very blatant propaganda, like what you see in politics, with almost every ad or poster smearing one thing, person, opinion, etc. Revealed propaganda tries desperately to make people join it's cause and hate the other thing. Hope this helped!

When Germany invaded Poland this was the beginning of what would later be called the second World war. A tense atmosphere was brewing up in Europe for a few years since then already because when Hitler's party took charge of Germany, it increasingly militarized the country and was preparing it for war.
Providing supplies to American and Allied troops fighting the war in Europe, Africa, and the Pacific required the efforts of all Americans. At home, citizens contributed to the war effort by rationing consumer goods, recycling materials, purchasing war bonds, and working in war industries.
Hope that helps and feel free to ask me more questions :)
