sentences:  A skilled fisherman can methodically explore many possible hiding places for fish by continually casting and retrieving a plug.Theoretically, any plug design will catch fish (most anglers use them to catch bass) — fish will, out of anger, hunger, territorial protection or simple curiosity, occasionally strike at any small object moving or falling through the water.But some plugs have become famous for their high degree of effectiveness in the hands of a good fisherman, while others come and go from the market quickly when found to have limited success.
