Four rows of three circles in a line (1)

Jennie drew six circles on the fence and said to her teacher :

- now we can see two rows of three-in-a-line.

So what you have to do now is move one (and one only) of these circles in order to obtain four rows of three-in-a-line.

Look at the circles very carefully before you start.
