      Cell phones, a wonder of technology, are used to report emergencies, locate directions, call home,
      message friends, do business from the park or golf course. Life without them is now difficult to
      imagine. But Cellphones have been proven deadly if employed while driving a vehicle or walking down
      the street. The mistakes that cellphone users make are many and varied. It may be as trivial as getting
      off the wrong floor from a lift; or as serious as fatally falling down a flight of stairs. And most common
      of all: people getting knocked down by all kinds of vehicles. We should promote safety by following
      some rules. Never use a cellphone while driving, or while crossing or walking along a road. Always
      stop your vehicle carefully before you answer the phone. If you’re on a busy road where you can’t stop,
      and your phone rings, it is best to miss that call. If you get calls constantly, ask your service provider to
      activate voicemail-which will say that you’ll return the call later. If you have a passenger, place the
      phone where he or she can answer it for you. Whether you are in a taxi, bus, your own car or a friend’s,
      you must stop any driver from speaking on the phone while driving.

      iv) consensus          {       }        d. incapable of getting tired
      v) exonerate           {       }        e. extremely desirous of money
