Final answer:
Dot's response to Sophie is not explicitly mentioned in the given references, but she would likely assert her own worthiness without comparing herself to others.
Step-by-step explanation:
Dot's response to Sophie when she told Hester and Anadil to look at themselves and look at her for proof she belonged in the School of Good is not explicitly mentioned in the given references. Therefore, we can't provide a direct quote or statement from Dot. However, based on the context and the characters involved, we can assume that Dot would likely respond in a calm and confident manner, asserting her own worthiness to be in the School of Good. She might say something like, 'I don't need to compare myself to anyone else to prove that I belong here. My actions and intentions speak for themselves.'
