Final answer:
The question requires contrasting Colonel Pickering and Henry Higgins from George Bernard Shaw's play Pygmalion and discussing their treatment of Liza. The provided texts do not correspond to the characters, making it impossible to accurately provide contrasts based on the given references.
Step-by-step explanation:
The question asks to contrast Colonel Pickering and Henry Higgins in terms of manners and behavior and to discuss the implications of their different treatments of Liza. Unfortunately, the provided references do not contain any direct information about Colonel Pickering, Henry Higgins, or Liza to adequately answer this question. It appears there is a mix up with excerpts from texts unrelated to the characters in question, who are from George Bernard Shaw's play Pygmalion.
Typically, Colonel Pickering is portrayed as a gentleman with impeccable manners, treating Liza with kindness and respect. In contrast, Henry Higgins is often seen as more brusque and less concerned with etiquette, treating Liza as an experiment rather than a person. The treatment of Liza by these two characters brings to light themes related to class, gender, and personal transformation.
