Hmm, a problematic one, given the rubric. The Free City of Danzig was part of Germany in 1927. The modern name of Germany is Germany. That said, Danzig is now Gdansk, which is now in Poland. The rubric states "give the modern name of the country'. The fact that the borders have changed doesn't mean it wasn't Germany at the time of Grass's birth.
I'm a little bit troubled with Homer here. Though his place of birth (as his existence) is not known, he mostly is thought to be born in Ionia, now modern Turkey.
