skywrdbound,
i vaguely remember one question like that on form 1. i can't confirm i actually got it right, but i think they make it easy to narrow down.
if you're having trouble, it may help you to remember the prime meridian is in greenwich, england and the long lines move in 15 degree increments. if you come across a quesiton like that, try to gauge where the lat and long lines are in relation to the prime meridian and the equator. you should be able to easily discern between the black sea and baja mexico using that method. taking a quick look at a globe should help too.
