Welcher deutsche Staat hatte eine schwarz-rot-goldene Flagge mit Hammer, Zirkel und Ährenkranz?Which German state had a black-red-gold flag with a hammer, compass, and wreath of grain?

Explanation

The German Democratic Republic (DDR) added a hammer, compass, and wreath of rye to the black-red-gold tricolour in 1959, representing workers, intelligentsia, and farmers. The Federal Republic kept the plain tricolour, so the emblem made the two German flags easily distinguishable until 1990.
