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: Dr. Henry Jekyll, a kind English doctor in Victorian London, is certain that within each man lurks impulses for both good and evil. He is desperately in love with his fiancée Muriel Carew and wants to marry her immediately. But her father, Brigadier General Sir Danvers Carew, orders them to wait. One night, while walking home with his colleague, Dr. John Lanyon, Jekyll spots a bar singer, Ivy Pierson, being attacked by a man outside her boarding house. Jekyll drives the man away and carries Ivy up to her room to attend to her. Ivy tries to seduce Jekyll but, though he is tempted, he leaves with Lanyon.
When Sir Danvers takes Muriel to Bath, Jekyll begins to experiment with drugs that he believes will unleash his evil side. After imbibing a concoction of these drugs, he transforms into Edward Hyde—an impulsive, violent, amoral man who indulges his every desire. Hyde finds Ivy in the music hall where she works. He offers to financially support her in return for her company. They stay at her boarding house where Hyde sexually abuses and psychologically manipulates her. When Hyde reads in the paper that Sir Danvers and Muriel are planning to return to London, Hyde leaves Ivy but threatens her that he'll return when she least expects it.
Overcome with guilt, Jekyll sends £50 to Ivy. On the advice of her landlady, Ivy goes to see Dr. Jekyll and recognizes him as the man who saved her from abuse that night. She tearfully tells him about her situation with Hyde, and Jekyll reassures her that she will never see Hyde again. But the next night, while walking to a party at Muriel's where the wedding date is to be announced, Jekyll spontaneously changes into Hyde. Rather than attend the party, Hyde goes to Ivy's room and murders her.
Output:
Who is with Henry Jekyll when he sees a woman needing help?
