Quiz

A “lying” rectangle is divided in half by a horizontal line segment. The lower half is, in turn, divided in half by a vertical line segment, and the upper half is divided into 3 equal parts by two more vertical line segments. You need to draw a curve without lifting the pencil from the paper, crossing all the line segments of the resulting figure (two or more line segments lying on the same line are not counted as one line segment; intersection means "inside the line segment") exactly once. How?

P.S. A well-reasoned "It's impossible" is also an answer.
