Truth or Lie?
2. People who can't hear can use the telephone.
Sorry! Your answer is incorrect.
With a device called a Text Telephone (TT), people who can't hear can communicate with others who have similar devices through the telephone lines. If a person who is deaf wants to order a pizza from a pizzeria that doesn't have a TT, he or she can call a special number called a Telecommunications Relay System where someone will call the pizzeria and place the order for the person who can't hear.
