So, I’m not too sure on how to answer this

Whatever has the most unprotected land.

Explanation:

I cannot see which country is the lightest color/shade of grey on your paper in the picture, but if you see, its given you a meter of 'greatest percentage of protected land.' The darker color being more protected than the lighter. this corresponds with the map. Find the country with the lightest color, state it, and say why. (Use the meter as your reasoning)

If this makes sense, I hope it helps! :)
