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?

Passage: The term "Gadget" was a laboratory euphemism for a bomb, from which the laboratory's weapon physics division, "G Division", took its name in August 1944. At that time it did not refer specifically to the Trinity Test device as it had yet to be developed, but once it was, it became the laboratory code name. The Trinity Gadget was officially a Y-1561 device, as was the Fat Man used a few weeks later in the bombing of Nagasaki. The two were very similar, with only minor differences, the most obvious being the absence of fuzing and the external ballistic casing. The bombs were still under development, and small changes continued to be made to the Fat Man design.To keep the design as simple as possible, a near solid spherical core was chosen rather than a hollow one, although calculations showed that a hollow core would be more efficient in its use of plutonium. The core was compressed to prompt super-criticality by the implosion generated by the high explosive lens. This design became known as a "Christy Core" or "Christy pit" after physicist Robert F. Christy, who made the solid pit design a reality after it was initially proposed by Edward Teller. Along with the pit, the whole physics package was also informally nicknamed "Christy['s] Gadget".Of the several allotropes of plutonium, the metallurgists preferred the malleable δ phase. This was stabilized at room temperature by alloying it with gallium. Two equal hemispheres of plutonium-gallium alloy were plated with silver, and designated by serial numbers HS-1 and HS-2. The 6.19-kilogram (13.6 lb) radioactive core generated 15 W of heat, which warmed it up to about 100 to 110 °F (38 to 43 °C), and the silver plating developed blisters that had to be filed down and covered with gold foil; later cores were plated with nickel instead. The Trinity core consisted of just these two hemispheres. Later cores also included a ring with a triangular cross-section to prevent jets forming in the gap between them.
What is the code name of the device that was developed after it had a code name?

Passage: Ned Ravine, who is both a police officer and lawyer (who often defends the people he arrests), believes that he knows everything about women, and says that he will throw away his badge if anyone ever proves him wrong. While on a stakeout, he encounters a seductive woman named Lola Cain; the next day, Lola shows up at his law office, saying that she needs him to look over some papers she has come across. Meanwhile, Max Shady, who was just released from prison after seven years, starts stalking Ned, planning to kill him for failing to successfully defend Max in court.
Ned's wife Lana and her car mechanic Frank, with whom she is having an affair, start plotting to kill Ned in order to collect on his accident insurance, which has a triple indemnity rider; if Ned is shot, falls from a northbound train, and drowns in a freshwater stream, Lana will collect nine million dollars.
Lola gets Ned to come to her house to examine the "papers", which are actually a laundry receipt and an expired lottery ticket, and the two of them end up having sex in various wild ways. The next morning, Ned says that they can never do that again because he loves his wife; this drives Lola to start stalking Ned.
A few days later, Ned takes the train to go to a legal symposium; Lana and Frank are also on the train, and so is Max. When the train passes over a lake, Lana shoots Max 36 times with a revolver, mistaking him for Ned, and he backflips through the door to his death; Ned thinks that Lana had acted to save his life. He arrests Lana, and then defends her in court, getting her cleared of all charges. Lana later kills Frank, believing that he was going to abandon her, by pinning him against a wall with his power drill; Lola witnesses this, and starts blackmailing Lana.
