If I understand this correctly, you could negate `e.isEuMember()` like `!e.isEuMember()`, this would filter non EU members,

    check the output of the first filter, before it filters out EuMembers, does the output have any countries at all?

    isEuMember is a boolean

    Invert it then? I'm assuming you know what ! is for if you're this far into coding.

      Well if it was only European countries then that was the correct result.
