I would say that the answer should be "Helen's challenges with the frustration of learning to communicate".as a blind-deaf person and the excellent analogy with being shrouded in fog and not having how to determine where she was headed but love giving her the light to find her way and eventually get a degree at university.
Can u add and image of the story so we can read it?
The most effective question is what does the character learn. In most every story, the character learns something from their mistakes. The other questions are mostly irrelevant.
