To note: Olinda is a municipality, not a neighborhood, and it’s not particularly black, the entire coastal Northeast is the blackest region in Brazil, it was the place where Brazil’s first slave-using monoculture (sugarcane) was mostly produced.
The statement "East Berlin S-Bahn trains ran through without stopping when trains crossed into West Berlin territory" is doubly confused - it was WEST Berlin U-BAHN trains that ran through without stopping when trains crossed into EAST Berlin territory.

Thank you for that. I made edits accordingly to your edits.
