Since all four hints have been given already, a correct solution submitted now would be worth one point.

You may submit your solution as an individual, as a school group, or as a non-student. If you are under the age of 18, please make sure you have the permission of a parent or teacher before entering personal information on this website. If you are submitting as an individual, we require you to submit your first name, your last initial, your email address, your grade level, and your home state. We ask for this information in order to know who is playing our game and to help ensure that each participant is a real person. A valid email address is required so that we can get in touch with you to tell you whether your solution is correct or not—but we will never give out your email address or personal information to anybody. If you make it onto our list of top performers, we will post only your first name. If you are submitting as a class, we require you to submit your school name, your city, your state, your grade level, and your teacher’s first name and last initial. If your class makes it onto our list of top performers, we will post only your school name, home state, and grade level. If multiple classes from the same school are submitting separately, please add in something to distinguish them on the submission form (for example, “5th period” or “AP Human Geography class”).

When you give your solution to this week’s map, please be as precise as possible. A one-sentence explanation is sufficient, but you would be welcome to give a more detailed answer if you so chose. If you explain why you came up with the answer that you did, then we can do a better job of giving you tips for future solutions when we reply to your submission. This is especially important if your submission is incorrect and you wish to figure out where you went astray.
