This question seems to be incomplete. However, there is enough information to find the right answer.
Answer: Pearl notices that the scarlet letter on her mother's bosom has paved the way for lack of sunshine in her mother´s lie.
Explanation:
The question refers to The Scarlet Letter: A Romance (1850), by Nathaniel Hawthorne.
In the provided excerpt, Pearl notices that the sun seems to dislike her mother because of the scarlet letter on her bosom. Pearls comment about how that doesn´t happen to her because she doesn't have the scarlet letter yet implies that she thinks she will when she grows up to be an adult woman.
This means that she doesn´t think that the scarlet letter is unique to her mother, but something she will also get when she grows up. And she doesn´t admire her mother for it, as she dislikes how the sun runs away from her.
Pearl´s words imply that she, who is usually aware of things that others can´t see, has realized that the lack of sunshine in her mother’s life is caused by the scarlet letter on her bosom.
