(2). [5 points] Consider the arrangement A of 7 black lines L = {li, l2, ..., l7} below. The arrangement is almost simple: there are no two parallel lines, and the only place where 3 or more lines pass through a common point is the highlighted vertex labelled v, which has 3 black lines passing through it. (a). What is the complexity of the zone (within the arrangement of the 7 black lines of the red line? (The red line exactly passes through the two highlighted vertices.) (2).
