Dress warmly. It takes about two hours to go through all the stops and answer all the questions. But, if you walked along the previous routes, then you will answer many questions faster. All answers are numbers. Each correct answer opens the way to the next stop. You will need ingenuity, a little knowledge, and do not hesitate to ask people, look for answers on the Internet and use any tips. Let's try to find the number - the answer to the question. For example, to go to the next stop, you need to add the number of participants to the start date of the seminar and divide it by two. That is, 36 plus 8 divided by two - we get 22. Enter 22 in the answer field, and you will open the path to the next stop.
