Query: On the connectivity of the realization spaces of line arrangements   We prove that under certain combinatorial conditions, the realization spaces
of line arrangements on the complex projective plane are connected. We also
give several examples of arrangements with eight, nine and ten lines which have
disconnected realization spaces.
