My mother used to ask me what was the most important part of the body.Through the years I would   36  the correct answer.When I was younger, I thought   37   was very important to us as humans, so I said, "My ears, Mommy." She said, "No.Many people are    38 .But you keep thinking about it and I will ask you again soon."
Several years passed before she asked me again.Since    39 my first attempt, I had often thought over the correct answer.So this time I told her, "Mommy, sight is very important to everybody, so it   40_  be our eyes." She looked at me and told me, "You are learning fast, but the answer is not   41 because there are many people who are blind."
