Mr. Baker is retired at home now. He feels bored every day and he thinks he is growing older quickly. When he watches TV, he has to turn it up. But this often disturbs his neighbors. So he decides to buy a hearing aid. As he is a _ man, he doesn't want to pay much money for a hearing aid. One day, he went to a clinic  and asked the clerk, "How much do these hearing aids cost?" "That depends," said the clerk. "They cost from 2.00 dollars to 2 000 dollars." "Let me see the $2.00 model," he said. The clerk put the device  around Mr Baker's neck. "You just put this button in your ear and run this little string  down to your pocket," he explained. "How does it work?" Mr. Baker asked. "For $2.00 it doesn't work," the clerk answered. "But when people see it on you, they'll talk louder!" Mr. Baker was angry, and he said, "I want a hearing aid that really works!" What do you think would happen in the end of the story?
Mr. Baker left the clinic without the hearing aid. Mr. Baker paid $2 for the hearing aid. Mr. Baker might buy another model of hearing aid. Mr. Baker might buy two hearing aids.
