Looking at the world via Google Earth offers striking images of the diversity of our planet and the impact that humans have on it. Today's entry is a puzzle -- part 2 in a series (part 1 here), in which we challenge you to figure out where in the world each of the images below was taken. (Unlike part 1, we're making this one multiple choice.) Note that north is not always up in these pictures. Also, be assured that, apart from a bit of contrast, these images are unaltered; they are exactly what Google and its mapping partners provide. So have a look at the images below, make your guesses, and see your score at the end. Good luck!
