What i think you did a typo
I believe the answer is A bit I could be wrong

Answer:
1. Margot was a very frail girl who looked as if she had been lost in the rain for years and the rain had washed out the blue from her eyes and the red from her mouth and the yellow from her hair. She was an old photograph dusted from an album, whitened away, and if she spoke at all her voice would be a ghost , this made her the odd one out from the other children and was usually kept away from as because of her weird behavior towards others.
2. Margot was fed up of the rain which kept falling and never stopped,
so she decided to not let even a drop of water on her head for she already had enough of it outside..
