At an international health conference held in Brazil recently, representatives of the US government made a joke when showing a map of Africa on a slide show: the corresponding locations of each African country on the map were all mismarked, causing participants to take pictures and upload them on social media. The US State Department later explained that the US team members “hurriedly” changed the slides before the event began, and only then did it go wrong.
