Bratwurst is a German word - so it borrowed it from German!
In german "brat" comes from "braten:" roast (in modern German) and Wurst means "saussage".
Bratwurst is very common in Germany and in Austria and it's also a kind of "street food" sometimes.
I believe it is merely asking you to write down what the images remind you of. Like, maybe a childhood memory or something that happened recently or long ago. or maybe something you have seen :)
Ambition can play a big role for motivation. Both positive and negative traits arise from it. The management of the one who carries the ambition has the potential to execute it in the harshest, and inefficient of ways. Their goals can be patient, or they can grow restless for achievement. Their ambition can be one that's toxic, or one of great opportunities. Whether or not influenced by power or vengefulness, their mindfulness will go on to affect their surroundings in the paths they choose to take.
