Answer:
She painted her ideas and thoughts.
Step-by-step explanation:
When you think about it, and really read the passage, don't think too hard. Ok what are my facts, she can't speak, and she draws and "dabbles" paint to express herself. It doesn't say anything about her writing songs. Her mother did, but she didn't. And its says nothing about studying as a teenager. So it must be the last answer,
She painted her ideas and thoughts.
