Answer: So from what I've gathered from reading this paragraph it seems that Eliza's nice and willing to help Higgin's to become a proper lady, But it seems that Mr. Pearce is not so nice and will be harsh.
Explanation:
Eliza: You are to live here for the next sixth months, learning how to speak beautifully, like a lady in a florist's shop. If you're good and do whatever you're told, you shall sleep in a proper bedroom, and have lots to eat, and money to buy chocolates and take rides in taxis. If you're naughty and idle you will sleep in the back kitchen among the black beetles, and be walloped by Mr. Pearce with a broomstick. *
I truly hope this helps!! :)
