Answer:
C. He thought reading was important.
Explanation:
After reading the text, we are able to strike out a few answers right off the bat with particular sentences.
Since Louis <em>"played the organ and cello"</em><u>,</u> we know that he didn't have a hard time learning music, so A is out.
There is no mention of Louis' liking of audio books and recordings in the text. It's only mentioned in the sentence: "<em>Even with the invention of audio books and recordings...", </em>which only serves as a conclusion to the passage and doesn't illustrate that Louis likes them. B is out.
The sentence <em>"For ideas, he studied codes used by the military"</em>, rules out letter D, since he didn't create the codes he studied. That would be counterproductive.
Therefore, Louis' creation of the Braille system makes C the correct answer. You can also conclude this just from the statement: <em>"He wanted to be able to read as quickly as people with sight."</em> Why else would Louis want this if he didn't think reading was important?
