Given the task definition and input, reply with output. 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: Jack and Sarah are expecting a baby together, but a complication during the birth leads to the death of Sarah. Jack, grief-stricken, goes on an alcoholic bender, leaving his daughter to be taken care of by his parents and Sarah's mother, until they decide to take drastic action: they return the baby to Jack whilst he is asleep, leaving him to take care of it. Although he struggles initially, he eventually begins to dote on the child and names her Sarah.
Despite this, he nevertheless finds it increasingly difficult to juggle bringing up the baby with his high-powered job, and though both sets of the child's grandparents lend a hand (along with William, a dried out ex-alcoholic who, once sober, proves to be a remarkably efficient babysitter and housekeeper), he needs more help. Amy, an American waitress he meets in a restaurant who takes a shine to Sarah, takes up the role as nanny, moving in with Jack after one meeting.
Although clashing with William and the grandparents, especially Jack's mother, Margaret, Jack and Amy gradually grow closer—but Jack's boss has also taken an interest in him.
Who finds it hard to raise the baby and do his job?
