Answer: The sentence provided is describing Clara.
Explanation: The sentence provided belongs to George Bernard Shaw's play Pygmalion and it is describing Miss Clara Eynsford Hill. In the play, Clara is Freddy's sister and, as well as his brother, she is presented as an ignorant snob at the beginning, but as a well-dressed woman. Moreover, she is always spending time with his mother, Mrs. Hill. For that reason, the sentence provided starts with "the daughter".
