"Great Britain, which long opposed construction of the canal for fear that it might fall into enemy hands, benefited more than any other nation... Instead of making Egypt powerful and independent, the Suez Canal provided the excuse for a British invasion and occupation of that country."
Education and learning was largely preserved during the Middle Ages through the Church and through the progress made during the age of the Roman Empire. The language of academia, for both of these reasons, was in Latin.
People who went into academia, learning to read and write and study other subjects, usually did so in Latin. This is both because the Roman Catholic Church usually administrated this education, and also because much of the texts that were studied were in Latin due to there origin in the Roman Empire.
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!
