Answer:
Doolittle's motivation is to trade his daughter in Act II for money.
Explanation:
"Pygmalion" is a drama written by George Bernard Shaw. The drama is about Professor Higgins, Colonel Pickering, and Eliza Doolittle, a flower girl. Professor Higgins bets with Colonel Pickering that he will change the ascent of Eliza and make her suitable for upper class.
In Act II, after accepting the bet, when Mrs. Pearce is making Eliza ready, Mr. Doolittle, Eliza's father, come knocking at Higgins door. The motivation with which he comes at his doorstep is to trade his daughter for money. Alfred Doolittle is a selfish and greedy father, who is ready to leave his daughter with Higgins and Pickering in exchange for some money. This reveals his true motivation of coming to Higgins house.
