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.

Ex Input:
Passage: Wedge Donovan is a tough construction boss, building airstrips in the Pacific for the U.S. Navy during World War II. He clashes with his liaison officer, Lieutenant Commander Robert Yarrow, over the fact that his men are not allowed to arm themselves against the Japanese. When the enemy lands in force on the island, he finally takes matters into his own hands, leading his men into the fray. This prevents Yarrow from springing a carefully devised trap that would have wiped out the invaders in a murderous machinegun crossfire, with minimal American losses. Instead, many of Donovan's men are killed unnecessarily.
As a result of this tragedy, Yarrow finally convinces the US Navy to form Construction Battalions (CBs, or the more familiar "Seabees") with Donovan's assistance, despite their mutual romantic interest in war correspondent Constance Chesley. Donovan and many of his men enlist and receive formal military training.
The two men are teamed together on yet another island. The Japanese launch a major attack, which the Seabees barely manage to hold off, sometimes using heavy construction machinery such as bulldozers and a clamshell bucket. When word reaches Donovan of another approaching enemy column, there are no sailors left to oppose this new threat. In desperation, he rigs a bulldozer with explosives on its blade, intending to ram it into a petroleum storage tank. The plan works, sending a cascade of burning liquid into the path of the Japanese, who retreat in panic, right into the sights of waiting machine guns.  However, Wedge is shot in the process and dies in the explosion.

Ex Output:
Whose men were unarmed against the Japanese?

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.

Ex Output:
Who finds it hard to raise the baby and do his job?

Passage: Vaughan Williams conducted a handful of recordings for gramophone and radio. His studio recordings are the overture to The Wasps, and the ballet Old King Cole (both made in 1925), Dona Nobis Pacem (1936), and the Fourth Symphony (1937). Live concert tapings include the Serenade to Music, and the Fifth Symphony, recorded in 1951 and 1952, respectively. There is a recording of Vaughan Williams conducting the St Matthew Passion with his Leith Hill Festival forces. In the early days of LP in the 1950s Vaughan Williams was better represented in the record catalogues than most British composers. The Record Guide (1955) contained nine pages of listings of his music on disc, compared with five for Walton, and four apiece for Elgar and Britten.All the composer's major works and many of the minor ones have been recorded. There have been numerous complete LP and CD sets of the nine symphonies, beginning with Boult's Decca cycle of the 1950s, most of which was recorded in the composer's presence. Although rarely staged, the operas have fared well on disc. The earliest recording of a Vaughan Williams opera was Hugh the Drover, in an abridged version conducted by Sargent in 1924. Since the 1960s there have been stereophonic recordings of Hugh the Drover, Sir John in Love, Riders to the Sea, The Poisoned Kiss, and The Pilgrim's Progress. Most of the orchestral recordings have been by British orchestras and conductors, but notable non-British conductors who have made recordings of Vaughan Williams's works include Herbert von Karajan, Leonard Bernstein, Leopold Stokowski, and, most frequently, André Previn, who conducted the London Symphony Orchestra in the first complete stereo cycle of the symphonies, recorded between 1967 and 1972. Among the British conductors most closely associated with Vaughan Williams's music on disc and in concert in the generations after Boult, Sargent and Barbirolli are Vernon Handley, Richard Hickox, Sir Mark Elder and Sir Andrew Davis. Record companies with extensive lists of Vaughan Williams recordings include EMI, Decca, Chandos, Hyperion and Naxos.
