  "BEL": "Brussels", 
  "LIE": "Vaduz", 
  "BGR": "Sofia", 
  "USA": "Washington D.C.", 
  "MEX": "Mexico City", 
  "BRA": "Brasilia", 
  "IND": "New Delhi",

Here you go:

for (key, value) in world {
    // Enter your code below
    switch key {
    case "BEL","LIE","BGR": europeanCapitals += [value]
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)

you need a switch statement, with a case for each type of capital. The editor will accept either way of appending Strings to String arrays: the append() method or the +=[] way.
