I think the correct answer would be the second option. The Soviet Union joined the allies because Hitler had broken a pact and attacked. The pact was called the German-Soviet nonaggression pact. This pact was regarded by Hitler as a tactical move. It was signed on the year 1940 and after a year Hitler attacked the Soviet Union.
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!

No Gore did not win a mandate in 2000. He had only 48% of the popular vote which is not considered as a victory. He also lost many critical states which meant that he was not qualified to be president.
Clinton failed to have a majority vote in 1992. However, he did win a plurality of the states and was suited to be president per the Electoral College.
Hope this helps you :P
