I was telling simplr jnr that I had no new ideas for a puzzle, so she came to the rescue with a couple. Here is one of them. My immediate reaction is that it looked too difficult, a 4 at least, but she said no, it's easy, just a 1.5.
I had her explain the strange aspects of the drawing to me. She tells me that the double arrows show that the three lines so marked all point in the same direction and that the drawing is not to scale on purpose so that I cannot cheat by using a protractor. With those questions answered, we agreed on a difficulty of 2.
