Letter Chain #4

Clearly the most important "quiz" on JetPunk.

In 90 seconds, make every country disappear from the map by typing both its first 2 letters and its last 2 letters.

Guess what each group of three things has in common. As you guess each answer correctly, it will be drawn in to create a work of art.

Upon answering the first question, all subsequent questions will refer to the previous answer. Better not miss any!
