What sentiments would the image of the banner-festooned
Nuremberg castle inspires in the minds of Germans? Why would the map of
Germany provoke bitter memories for Germans?

1. The image of the Nuremberg castle and the old map of Germany would be painful as a reminder of the Nazi past.

2. These memories provoke a resentment in the Germans.

Explanation:

In Germany the scars of a fascist past have remained to this day as it was one of the nations that was radicalized the most and caused the most damage to the world for it.

The nation deeply resents that pasts and symbols that represent it so the image of banner-festooned  Nuremberg castle would remind them of that Nazi celebration of bigotry.

The image of a divided Germany will also be too much to take for them so that would give away a resentment.
