Text: the um some buildings do it depends on the location the area i live in right now is is real good as far as crime rate is concerned and we don't have anything at all no burglar alarms no guards some some places do have guard gates that you have to get through or electronic access gates and things like that
Entailment: The crime rate around here is pretty low, so we don't have much need for security systems.
Contradiction: We've had so many burglaries lately that our neighborhood has begun to install high tech home security systems.
