Answer: Rifah : Hello, Maria! Why are you looking so sad?
Maria : The news of the death of all members of a family made me sad.
Rifah : How pathetic! Really, it's very sad that there's not a single day you'll find without news of road accident.
Maria : Can you tell me the reasons of so many road accidents?
Rifah : Reckless driving, violation of traffic signals, overloaded vehicles and lack of traffic police are the main causes of road accident, I think.
Maria : What can be done to reduce road accident? Do you have any idea?
Rifah : Drivers should be given proper training. Unfit and unlicensed vehicles should be banned. Besides, people should be made aware of traffic rules and signals.
Maria : Thank you for the discussion.
Rifah : You're welcome.
