The word or phrase that best describes the political and religious atmosphere of the sixteenth and seventeenth centuries is "tumultuous" (D). During this period, the church was in a crisis. It was losing power and the European peasants were rising up against the way they were being treated by the church and the noblemen. The Reformation also moved the centre of power from the Roman Catholic Church to the German Lutheran church. Martin Luther was one of the leaders of the Reformation.

Informal speeches should not be given at an award ceremony like the one presented in the question above. This type of ceremony requires a formal wording, embedded in a serious speech, without slang, without jargon and without words of a relaxed tone like the speech above, which presented a choice and words very inappropriate for the occasion, like the word "thanks," for example.
