Given the question: I'm taking a test and have to guess the right answer to the question after the article. Article: At thirteen, I was diagnosed with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not. In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, "Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it." She glanced down at me through her glasses, "you are no different from your classmates, young man." I tried, but I didn't finish the reading when the bell rang. I had to take it home. In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots , which opened up a whole new world of knowledge to the blind. Wasn't I the "blind" in my class, being made to learn like the "sighted" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up? I didn't expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day with an "A" on it. At the bottom of the paper were these words: " See what you can do when you keep trying?" Question: What is the main idea of the passage? Options: A: The disabled should be treated with respect. B: A teacher can open up a new world to students. C: Everyone needs a hand when faced with challenges. D: One can find his way out of difficulties with efforts.
The answer is:
D
