Answer
Brief Explanations:
This is a speech at the opening of a significant structure (the Brooklyn Bridge). The language used like "profound satisfaction", "vicissitudes" is complex and formal. The context of a ceremonial speech (opening of a bridge) where the mayor is accepting the bridge on behalf of the city implies an informative purpose (letting the audience know the bridge is accepted, talking about the years of work etc.). There's no indication of teaching scientific facts (no technical details), no casual or humorous language (so not informal for persuasion or entertainment).
Answer:
formal; he uses complex words that are appropriate for the ceremony, and his purpose is to inform his audience.
