Help with Roots puzzle (town puzzle)

Could you please help me - i cannot understand how the roots must be connected. I connected them, but it is not the right solution. So how can i see how i can rotate them? And what is wrong in this picture?

I made the same mistake. You need to create a connection in the middle.

Thank  you very much!) But i think it should be better if we have some explanations for this puzzle :) Because the roots are connected pro forma. It is the second time when i connect them wrong :D

You need to create a connection in the middle.

I don't know about that, but there seem to be a more obvious mistake that the C shaped root to the left is connected only one way.

You are right, but you can see this mistake only if you have rotated the root already. The attempts are limited, so you cannot fix it. So it is necessary to connect all the parts of precision - and you do not know which roots mutch up. You can create many 'right solutions' but you will see your mistake only after the move of root... And you cannot  try another connection. may be it is part of 'fun'of course, but it is annnoying :))
