Query: Applications of Level Curves to Some Problems on Algebraic Surfaces   In a previous work of the authors, a result to algorithmically compute the
topology types of the level curves of an algebraic surface, is given. From this
result, here we derive applications based on level curves to determine some
topological features of surfaces (reality, compactness, connectivity) and to
the problem of plotting.
