You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Captain Crewe (played by Ian Hunter), called to fight in the Second Boer War, has to leave his daughter Sara with her pony at Miss Minchin's School for Girls. With all the money Captain Crewe can offer, Miss Minchin gives Sara a fancy, private room.
Although worried about her father, Sara is distracted by riding lessons. It is during these riding lessons that Sara helps contrive meetings between Miss Rose, her teacher, and Mr. Geoffrey, the riding instructor, who is also the grandson of the mean-spirited next door neighbor, Lord Wickham. Sara hears news that Mafeking is free and expects her father will soon come home. Miss Minchin throws Sara a lavish birthday party. During the party, Captain Crewe's solicitor arrives with the sad news that Captain Crewe has died and his real estate, the basis for his wealth, has been confiscated. Miss Minchin ends Sara's party abruptly. Without her father's financial support, Sara becomes a servant, now working at the school she used to attend. Sara gains new solace in a friendship with Ram Dass who lives next door.  She also receives support from Miss Minchin's brother, Hubert, who does not agree with her treatment. Miss Rose and Mr. Geoffrey are found out and fired. Geoffrey joins the military.
Output:
Whose treatment does Hubert object to?
